Understanding Hooke's Law: The Foundation of Elasticity| Chapter 5 Physics 9th

HOOKE'S LAW   Introduction In physics, Hooke's Law is one of the fundamental principles governing how objects deform under external forces . Named after the 17th-century British physicist Robert Hooke, this law provides a crucial understanding of the behavior of elastic materials, such as springs and rubber bands. Whether stretching a rubber band or compressing a spring, Hooke's Law helps explain what happens when forces act on these materials. What is Hooke's Law: Hooke's Law states that the force F needed to extend or compress a spring by some distance x is proportional to that distance. Mathematically, it is expressed as: F= -kx Here k represents the spring constant, which is the measure of the stiffness of the spring, and x is the displacement from the displacement position.  The negative sign indicates that the force exerted by the spring is in the opposite direction of the displacement.  Understanding the Spring Constant: The spring constant k is a critical co

                   FORMING HABIT

How long  it take to form a habit? I looked for an answer, the same way most people do now a days. I asked Google. The  answer I got was 21 days. It seemed  that if you repeat the behavior everyday for 21 days you can  form a brand-new habit. Then I  asked can  one change all type of behaviors in 21 or some types. I was not able to find an answer. All I could find out was that, if it was exercise, smoking writing diary or turning cartwheels; you could do 21 days. The important thing was to maintain a chain of f21 days  without breaking it.

One psychologist Mr.  Mohan decided to do some research to find out if all new habits could be formed in just 21 days. About 100 people from the Multan University participated in research.  They were asked to choose behavior that they wanted to turn into habit. They all had to choose something they didn’t already do that would be repeat every day. What do you think the result was ?

The result showed that on average it took 66 days until a habit was formed. However this does not mean that people weren’t able to form new habits in 21 days. According to the study, findings some habits could be formed in 21 days while some could take as long as 254 days. So 21 days to form a habit probably right as long as you want to do is drink a glass of water after breakfast.. Anything harder is likely to take longer to become a  really strong habit and in the case of some activities much longer.

EDITING

    THE WISE KING

Rich man was on his death bed. He told his sons to dig the ground under his cot and share the buried wealth after his death. When he died the sons started digging. One of them found a vessel full of jewels and pearls, other a vessel full of gold and silver coins, the third one a vessel full of bones, and fourth a vessel full of dust. The last two quarreled with first two and said that the richest should be shared equally amongst them.  The first two did not agree.

Actually all four decided to put there case before the king. The King listen to their story and decided that the one who got jewels should kept them  and the one who got the coins should also keep them. The other two  brothers  felt very sad when they heard this.

Then the king looked to another two sons and said that the one who has vessel full  of bones was to be owner of the cattle left by his father and one with vessel full of dust was to be owner of land owned by rich man.

The decision by the king was liked by all the brothers. They were amazed at the king’s wisdom. They were satisfied and content with the decision.

                             FOUR SEASONS

There was a man who had four sons, he wanted his sons to learn not to judge things too quickly then he send each of them one by one to go and look at pear tree that was a great distance away.

The first son went in winter, the second in spring, the third in summer and the youngest son in autumn. When they all had gone and come back he called them together to describe what they had seen. The first son saw that the tree was ugly, bent and twisted. The second son said, “No, it was covered with green buds and full of promise.” The third son disagreed; he said that it was laden with blossoms that smell so sweet looking so beautiful. It was most graceful thing, he had ever seen. The last son disagreed all of them; he said it was dropping with ripe fruits., full of life  and fulfillments.

The man then explained to all his sons, that they were all right, because they had all seen but only one season in tree’s life. He told them that you cannot judge a tree or a person by only one season or on the basis of knowing about only one aspect of his life. So don’t let the pain of one season destroy the joy of all the remaining. Don’t judge life by one difficult season or people on the basis of one bad example.

 READING COMPREHENSION-II TEST 02 PASSAGE 01:               A team of researchers has found that immunizing patients with bee venom rather than the crushed bodies of bees can better prevent serious and sometime fatal sting reaction in more than one million Americans who are hypersensitive to bee stings. The crushed body treatment has been standard for fifty year, but a report released recently is said that it was ineffective. The serum made from crashed bodies of bees produced more adverse reaction than the injection of venom did.     The research compared the results of crushed body treatment with the results of immunotherapy, that uses insect venom and also compared with the results of placebo. After six or ten months of immunization, allergic reactions to stings occur in seven of twelve patients treated with the placebo, seven of ten with crushed body  extract and one of the eighteen treated with the venom. 1. What is the main topic of the passage     a. A new treatment for people
