Pressure can be defined as a continuous physical force exerted on or against an object by something in contact with it. Thrust is the force acting perpendicularly on any area.

The uses of pressure are various as:

• Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn.
• When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.
• Skis have a large area to reduce the pressure on the snow. This ensures that the skis do not sink into the snow too far.

Unit of thrust = Newton(N)

Pressure(P)= Thrust(f)/Area(A)

Unit of pressure = {Newton(N)/ meter²(m²)} Pascal

                                = Nm^-2

                                = dyne/cm²

Other units of pressure are barometric pressure

• Mm Hg (1 torr) (ii) cm Hg (iii) m Hg

1 atmospheric pressure = 0.76 m of hg column

The calculation of pressure is = Pressure(P)= {(Area*height) density of liquid*Acceleration due to gravity}/Area

= (A*h) d*g/A

=h*d*g

Height of Hg column to measure atmospheric pressure in standard condition = 76 cm of hg 

P=hdg

= 0.76*13.6*10³*10 Nm^-2

Acceleration due to gravity = 9.8ms^-2

What height of water will be required to measure atmospheric pressure instead of hg

ANS- H * D_(water) * G = 0.76*13.6*10³

              ⁼ H*D_(water)= 0.76*13.6*10³

         = H*1000= 0.76*13.6 * 10³               (Density of water = 1000 kg m-3)

          = H= 10.336

                        Water                                               30 cm

                          Hg                                               20 cm

                  P                                                                

Calculate pressure at P

P= H*d*g

P= (0.3*1000*10) + (0.2*13.6*10³*10)

  = (0.3+0.2+13.6) *10³*10

  = (0.3+2.72) *10³

 = 3.02*10³ * 10 Pa

Anytime have you have been given a task to complete, but thy feel that you are running out of time.You look at clock then again do work,again look at clock. Let’s face it,this is majorly due to lack of time management or not doing your things on time. How does time management help you.I will tell 6 points on benefits of time management

Reason#1

It improves your self-discipline Let’s face it, if you have good time management skills, the chances are that you’re highly self-disciplined. You’re the kind of person who stops procrastination dead in its tracks and drives forward to achieve your goals. This self-discipline improves other areas of your life too, from your career to your relationships. In other words, the better you get at time management, the better your self-discipline will be. This will make you more successful at meeting goals in all areas of your life. Before , when I had no idea of time management , I always did my work at last moment some time even got delayed in work and even missed the submission date many times. Got quite marks cut, felt like I had no discipline. Only till when I started applying time management in my life, I made fix routines of work, did a bit of the assignment everyday and on final day of submission, I felt relaxed and more confident.

Reason#2

It improves the quality of your work Having good time management skills doesn’t mean that you pull all-nighters to meet a deadline. It means that you manage your time effectively and space out your work while keeping your regular sleeping routine. According to research, almost half of Americans regularly get insufficient or low-quality sleep and report that this interferes with their daily lives. You need a good night’s sleep if you want to produce quality work; good time management skills will help you get the rest you need. During fourth standard I always got my exam schedule 2 weeks before the start of exam I completely relaxed till eve of the exam.That night I always took out my book first time to get ready for the exam of next day. I woke up till late night. Then, I started using different method . I started studying everyday and at evening before exam I did final revision , I felt relax, confident ,got more sleep ,Overall I felt great for next day.

Reason#3

Winding down is essential Between work, family commitments and running errands, most of us don’t get enough time to relax. If you want to have enough time to unwind, relax and prepare for the following day, good time management skills are essential. You need to know how to organize your work times and your break times to recuperate mentally and physically after a long day’s work. My friend studies a lot, he does many other stuffs like drawing, singing and many more things. He never got time to relax himself ,he used to sit at 9 and get up at 5.He got stressed and irritated, then I suggested him to take 10 mins break after every 2 hours. might be walk in home.He did that and now he feels better then ever eventhough he did not shift his time of 9am to 5pm

Reason#4

It reduces stress Take a few moments to reflect on your day: Do you feel as though you’re always busy, but accomplish little? Is there something that’s been keeping you up at night with worry? Are you unable to complete your work? If you answered “yes” to one or more of those questions, you’re likely feeling stressed. When you don’t feel as though you have control of your time and are always frantically working to meet deadlines, it’s highly likely that your health is suffering. Time management skills can help to reduce or even eliminate stress. Good time management skills will make you more productive, helping you to meet your deadlines and lowering your stress levels.

Reason#5

It opens up new possibilities One of the hidden dangers of poor time management is that it kills your chances of broadening your horizons and trying out new things. If you go through life rushing from one task to the next, you never have the chance to explore different opportunities. With more free time, you may be able to volunteer at a local charity or help someone in need. It’s hard to put a dollar value on these types of tasks but they are innately fulfilling and enriching. My friend, who was quite busy everyday felt sad. He wanted to learn new stuffs, wanted to  learn new things but did not have time to he always felt he wanted to learn but lack of time was the reason. But when he arranged or managed his time ,he saw how much time he had left.He started to learn new things in that time 

Reason #6
. It helps your personal relationships Good time management skills are essential to having strong and productive relationships. The more free time you have to spend with your friends and family, the better your relationships will be. You’ll make better decisions, have better ideas, and people around you will notice. Stronger personal relationships will enhance all aspects of your life.   

Now also do you really feel that you should not manage your time. Which would help you even more. That's up to you I would like to end with a quote “

One reason so few of us achieve what we truly want is that we never direct our focus; we never concentrate our power. Most people dabble their way through life, never deciding to master anything in particular.” – Tony Robbins

Is Ramayana an mere epic on Lord Ram or a lesson for all of us. I think, it is a lesson for me. Why? How? When I read for first time I learnt many things I will be telling 4 of them

Honour Your Word

One of the basic but strong messages given by Ramayana and the life of Lord Rama is rendering value to your own word. No matter what price you need to pay, but honouring your word is equivalent to worshipping the God within you. In Ramayana, King Dasharatha sent his eldest son, Lord Rama on exile to honour the promise he gave to his wife Kaikeyi without knowing that she would make such a demand in a bid to pronounce her son Bharath as the next King of Ayodhya. But a man of principles like Lord Rama didn’t question his father and without any second thought, he left the empire and his princely life to live life like an ordinary man for the next 14 years in forests. We learnt that it is not only our word but are parents too that we need to respect,no mater what hardship we need to suffer.

Pertinence of righteousness

Following the path of dharma, Maryada Purushottam Lord Rama took every step in his life to be truthful and righteous. He left the kingdom of Ayodhya when he was the true successor to the throne just to honour his father’s word. On the quest one of his subjects, he even asked Sita to go through Agni Pariksha (an ordeal of fire) to prove her sanctity. It is said that Lord Rama was in grief to have asked Sita to undergo this terrible test but to protect her respect and to prove her purity in front of his whole kingdom, he had to take this action, which he thought ,was right. We learn that no matter what you need to do always be truthful and righteouss .

Adhere To Your Dharma

The Survanshi dynasty of which Lord Rama belonged was known to give birth to kings of great valour. The event when his subjects objected on Sita’s purity, Lord Rama asked her to leave the kingdom while being disheartened, shows that Lord Rama believed in following his dharma of keeping his subjects happy. He sacrificed his marital life for the sake of his subjects. Though many people won’t consider this right but no matter what, we must train our minds to follow good principles that is advantageous for everyone concerned. We must stop letting our mind dwindle and be biased to situations .

Always follow dharm Be A Gentle and compassionate human being

Being in the mortal form, Lord Rama lived a princely life till he grew up but this king of Suryavanshi clan did not hesitate while eating fruits (ber), which were already tasted by a poor old woman named Shabri. In another instance, when his whole Vanarsena was busy building a bridge towards Lanka, he saw a squirrel putting in his best efforts too. To recognise his immense contribution in finding Sita, Lord Rama picked the tiny being from his hands and gently patted it with compassion. In our life, we too must never discriminate between people or judge them by their looks. Also the cruelty we show towards animals is far away from act of compassion. To conclude.

I would say that ramayan is a manual for human life. It teaches us the way to live and is applicable to everyone whether be a king or a commoner . As it teaches the concept of service leadership. I recommend everyone, to not only read ramayan but to study it, analysed it and understand it.

 Ganesh Chaturthi , also known as Vinayaka Chaturthi (Vinayak Chaturthi), is a Hindu festival celebrating the arrival of Ganesh to earth from Kailash Parvat with his mother Goddess Parvati/Gauri. The festival is marked with the installation of Ganesh clay idols privately in homes, or publicly on elaborate pandals (temporary stages). Observations include chanting of Vedic hymns and Hindu texts such as, prayers and vrat (fasting).[3] Offerings and prasad from the daily prayers,  that  are distributed from the pandal to the community, include sweets such as modak as it is believed to be a favourite of Lord Ganesh. The festival ends on the tenth day after start, when the idol is carried in a public procession with music and group chanting, then immersed in a nearby body of water such as a river or sea. In Mumbai alone, around 150,000 statues are immersed annually. Thereafter the clay idol dissolves and Ganesh is believed to return to Mount Kailash to Parvati and Shiva. The festival celebrates Lord Ganesh as the God of New Beginnings and the Remover of Obstacles as well as the god of wisdom and intelligence and is observed throughout India, especially in the states such as Maharashtra, Goa, Karnataka, Madhya Pradesh, Andhra Pradesh, Kerala, Telangana, Odisha, West Bengal, Gujarat and Chhattisgarh, and is usually celebrated privately at home in Tamil Nadu. Ganesh Chaturthi is also observed in Nepal and by the Hindu people elsewhere such as in Australia, New Zealand, Canada, Singapore, Malaysia, Trinidad and Tobago, Guyana, Suriname, other parts of the Caribbean, Fiji, Mauritius, South Africa[12] United States, and Europe. In the Gregorian calendar Ganesh Chaturthi falls between 22 August and 20 September every year. 
 At public venues, along with the reading of texts and group feasting, athletic and martial arts competitions are also held.[15]
 I like GaneshChaturthi as there are a lot of sweets offered to ganesha and other people, every year there is a function in our apartment with lots of fun and devotion by everyone serving Ganesha. He generally stays here for 3 days after which a group of people go for visarjan to nearby lake. Ganesh Chaturthi is generally on week days because of which we also get 2-3 days  of holiday. 
 
 
 
 
 
 

when you get up in the morning the clean fresh air washes out your sleep. Where as in the night when you go out you just can’t breathe .it is all because of pollution. If I had to define pollution I would say

 Pollution is something introduced into nature that is dirty unclean or has a harmful effect. Toxic waste dumped into water is an example of pollution. It refers to the chemical substances into the environment that is injurious for human, animals and plant life. The water, air noise and other forms of pollution is one terminology is known as the pollution of echo system.
 There are many types of pollution, that are water , visual , thermal , plastic , noise , light and air
 The measures of noise pollution are
 Normal conversation level- 40 – 60 db
 Health hazard- more than 80 db is safe
 If someone just comes and shouts in your ears whaaaa you would become Heebie - jeebies Heebie-jeebies
 These unusual words are used to express a feeling of fear and being uncomfortable
 Few examples are
 Heavy traffic – 90 db
 Sound of aircraft engine – 100 – 200 db
 Now imagine your house being just next to the airport, in midnight when the flight takes off how would it feel and so people don’t generally like to stay near airport. 
 The level of air quality is
 Good 0 – 50 no risk
 Moderate 51 -100 acceptable
 Unhealthy for sensitive group 101 – 150 sensitive group experience health effects normal people don’t get affected
 Unhealthy  151 – 200  everyone may experience health effect
 Very unhealthy  201 – 300  health alert :  everyone may experience health effects
 Hazardous 301 – 500 the entire population is effected
 Impact- Over a million die prematurely every year due to air pollution , according to non profit health effects institute. Over a two million children – half of which in Delhi , have abnormalities in their lung functions , according to Delhi heart & lung institute , over the past decade air pollution has increased in India significantly. Asthma is the most common health problem faced by Indians and its accounts for more than half of health issues caused by air pollution
 After , so much info about pollution . Let’s have some ways to prevent it

 Conserve energy
 Carpool , public transportation , bike or walk wherever possible
 Keep car , boat and other engines properly tuned
 Consider gas logs instead of wood
 Reduce no. Of trips you take in your car
 Conserve electricity  

Since the lockdown kicked off, I could not go out and was getting very bored .

So, we decided to go out to places less visited. We chose places of natural beauty which wasn’t far away as we had to come back in evening.  We wanted to avoid crowded place and to maintain social distancing. We planned basic precautions like wearing mask, carrying sanitizer. We carried even food and tea from home so as to avoid contacts.

We chose the places which, we assumed, no one else would. If that would be the case, we were to find out.

Planning

5 families planned for the trip. But 2 families dropped out for different reasons, leaving 3 families in the plan.

On the D-day, 1 car tire got punctured and Ankit Uncle was left stranded in Indiranagar. At the end, 2 families went for picnic – Amar Uncle’s and ours.

The first stop – Big Banyan Tree

Imagine a tree,450 years old and spread over almost 3 acres of land – size equivalent to almost 2.5 football fields. It’s a nature’s wonder and also boasts of  open space to run, play and have fun. The tree has so many secondary branches of the tree that no one knows where the primary root is. The tree has many branches which 100 of monkeys have made their habitat. It was fun to watch those monkeys jumping on and off the branches of the gigantic tree.

. 
Alas, to our disappointment, the entrance to the tree park was closed – thanks to COVID-19. Nonetheless, again thanks to the same covid-19, the adjoining restaurant was closed too. The restaurant has lot of open space and the provides a comprehensive view of the tree. We stood there for some time, took snaps and enjoyed the monkey business. The most adoring was the way mummy monkey was taking care of baby monkey.

Off to second pit stop

Having been disappointed by closure of the banyan tree, we decided to go to  Savandurga. Savandurga is  a hill 60 km west of Bangalore off the Magadi road. The hill is considered to be among the largest monolith hills in Asia. The hill rises to 1226 m above mean sea level and forms a part of the Deccan plateau.

Half way through to the monolith, we saw many cars parked on roadside. There was a small hillock nearby. Supercalifragilisticexpialidocius could be the term to describe the view. There was a dam nearby, river all over the place with lots of greenery and hills to rejoice the mind. Seeing the scenery, we decided to stay for a while, so we sat down and had tea, the tea was made tastier by the view we saw. Having enjoying the view for some time, we decided to move on to savandurga.

SAVANDURGA is a monolith approx.50 km away from Bangalore. It was huge. A monolith enough to exhaust a person trekking the wrong way in a min. With my dad I made a plan to go trekking there the coming weekend.

RAMNAGAR made famous by name RAMGAD in Sholay movie was our next destination. Against our expectations, there were many people visiting the place, we roamed and saw few places, sitting there we had our lunch, played football and cricket. The sun was moving towards west, sky turning light blue when we started back to home. We reached around 6.  Believe me this was an amazing trip. You people too should go

Due to COVID-19 there was a complete lockdown in the country which forced all schools to shut down

While we were waiting for news on school opening, which we knew will not come soon, we came to know that the classes will resume but online, rather than in-class.

The school then implemented e-learning for all classes,where the teachers and students entered a world of virtual classes . e-learning is based on formalized teaching methodlogy, with the help of electronic resources .At these times e-learning helps to be at home but still attend school.There are many platforms for this, like Zoom, Google meet and MS teams .On these platforms, the teachers store data ,records , assignments, dues etc. .

This process currently is practiced all over the world

In today’s world of technology,e-learning is less than a boon.It plays a vital role in the development of individual as well as future.The impact of techonology is witnessed in 10-years from school to e-learning

Let me list out a few advantages of online schooling

1.Lectures can be taken any number of times
Unlike classroom teaching,with online teaching you can acess the content multiple no. of times.This is specially useful at times of exam for revision

For me ,I have access to all the recordings and hence I watch it and clear my doubts.Which helps me understand the lessons better. 


2.Quick delivery of lessons
E-learning is a way to provide quick delivery of lessons..As compared to traditional classroom teaching method.

In school thee teacher used to take atleast 7-8 days for completing the chapter .Which was a lot of time.Nowadays we take 3-4 days for completing a chapter.which is ,2 online chapters complete in a span of  1 chapter i school, which is better as learning better in a lesser time.


3.More understandable
E-learning helps in better understanding because it gives space for studying virtually sharing presentation and videos

In school the teacher just came taught byspeaking or writing on the board.But at this time the teachers share few presentations and show some videos on the topic .Explaain the video and make us understand virtually but in a better way.
Eco-Friendly 
Online schooling prevents use of  buses and 90% paper,preventing pollution

When our schools were open and we had to travel to the school, it used to take 30-45 minutes of bus travel. Imagine the amount of pollution created by the bus in that duration. So many buses on the road just added up to the pollution. 

In comparison, now, the travel has been cut down, there is less pollution and we can see the impact - the trees are greener and happier. The air is calmer  

  
5.Consistency
E-learning enables educators to get a higher degree of coverage to communicate the message in a consistent way to target their audience.

"We need to bring learning to people not People to learning".

Solar Eclipse: A solar eclipse occurs when the position of the earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight .This occurs when the SUN,MOON and EARTH are aligned. Such alignment coincides with a new moon(syzygy) indicating the moon is closest to the elliptical plane. In a total eclipse, the disk of the sun is fully obscured by the moon.In partial only a part is obscured by the moon

World music day:The idea of the world music day was given by American musician Joel Cohan proposed an all night music celebration to mark the beginning of summer solstice

it is said that there are many more colours other than white and black.It is true for me between white and black were blue, purple, green and four shades of brown. I am talking about my journey from karate white belt to the black belt.

I started karate at age of three and half years of age.it took me 7 years to come to brown 1. Most of my friends,seniors,juniors quit as they felt it was of no use achieving black belt whereas some of them felt it’s better to play.

I didn’t give up even when I kept on facing difficulties my teacher pushing me all the way till the senior most belt before black.At the test I was all alone,I could not take the help of my teacher during the 1 month exam.During this exam I achieved discipline,punctuality and self-dependency in the test. I learnt many new things.I

improved the bad and strengthened my weak.The worst part came when it all came to exercises I somehow with difficulty,pain,hard work. It was the last test the 12 km run in 75 minutes.i did not expect myself to even complete in 90 mins.My father ran with me and pushed, encouraged and did everything he could to make me finish it in 70 mins.I felt it was the work of me,my teacher,parents for past 8 years.

Through my journey I learned how important it is to be disciplined,to be punctual,to withstand pain because after pain comes success.the success was in my hand on 31st January 2020.THE BLACK BELT

Yesterday,I got the opportunity to attend a panel disscusion . There were three panelist Vyom shekar ,Dr.Kirthi Kamath K.S.Anandram.They all put their put their views on advantages of reading books,how important it is to read books and how to develop reading habit.

I heard everything they said.Everyone might have some different opinions.So do I

Why is reading neccesary:Reading books helps us to relax,improves your concentration,it helps you to learn new words,whether you realise it or not it improves your vocabulary and the way of speaking to others sometimes it changes the way of looking at the world.

What to read:It doesn’t matter what you read,you read comics, novel, cartoon books, fiction, biopic, sports book,essay, news paper, essay.First you just need to build up reading habit by keep on reading.You either read on phone,kindle,buy book and read

Every child is different some one loves to read,he/she will read any book.how much ever thick.there are some people who don’t have the habit of reading books but want to develop the habit of reading books.I would suggest start with small books of your interestand develop the habit.Once you develop it no matter how thick the book is.You will love to read it.

NEVER COME INTO PARENT’S PRESSURE AND READ,READ ONLY FOR YOUR GOOD

The world iss reeling under the scare of a virus called Corona Virus. As of now, total number of human beings impacted by this virus has crossed 7 million worldwide. Most effected being US, Russia and Brazil. Even our own country, India, is among the top five impacted countries.

Let’s look at what this virus is, which has scareed whole of the world.

COVID 19 disease is an infectious disease caused by a newly discovered coronavirus.

The virus was first located in WUHAN , CHINA in December 2019.

Most people infected with COVID-19 will experience mild or moderate respiratory illness and recover without special treatment .Older people and those with other disease are most likely to serious illness.

The virus appears to spread easily among people, and more continues to be discovered over time about how it spreads. Data has shown that it spreads from person to person among those in close contact (within about 6 feet, or 2 meters). The virus spreads by respiratory droplets released when someone with the virus coughs, sneezes or talks. These droplets can be inhaled or land in the mouth or nose of a person nearby.

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness.

Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:

• Fever or chills
• Cough
• Shortness of breath or difficulty breathing
• Fatigue
• Muscle or body aches
• Headache
• New loss of taste or smell
• Sore throat
• Congestion or runny nose
• Nausea or vomiting
• Diarrhea

The precautions for this virus is to stay home,come out only when needed wearing a mask and having at least 2 meter distance with others. Wash your hands immediately after coming home.

STAY HOME,STAY SAFE
