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...

                          CRITICAL SUMMARY

Jameel entered his house in a gloomy mood. His father asked about his sad look. But he didn’t respond. As the family had finished the dinner, his mother again asked if there is any problem with him.  He replied the results of him and his sister Sara had been announced and they had passed with flying colors and now he is worried about his future studies. He told that as there was not any college in their village and the nearest one was in the city about 50 miles away, so he was upset about getting admission in any college.  He intended to become a doctor to serve the suffering humanity. Her mother suggested him that they could hire a horse cart for him and Sara to take them to the college. Their family friend Aunt Sadoori offered them to stay with her as far  as their studies ended in the city. His father didn’t agree this for Sara but her brother Khalid favored the idea. Thus they both started their college studies in the city with zeal and efforts. The family supported them with great difficulties and they also  gave tuitions to meet the expenses.

Twelve years later, they had chased their dreams by  becoming doctors  and setting up a hospital in the village  in order to treat the sick people.  They had their families with full of life and happiness.

EXERCISE #05: (USE BOOK FOR QUESTION)

In a poor zoo of Pakistan, a lion was very sad as he was given only 1kg of meat a day. The lion though was the luckiest lion on earth when one day the manager of the Dubai Zoo visited the zoo where the lion was, and requested the zoo management to shift the lion to the Dubai Zoo. The lion was very happy and started thinking of having an air conditioned cage and a goat to eat every day.

On its first day of arrival the lion was offered a big bag, sealed nicely, for breakfast.  The lion opened it quickly, but was shocked to see that the bag contained a few bananas only. The lion thought that since he had recently came from Pakistan the zoo management were worried about upsetting his stomach, so they had given him bananas.

Next day the same thing happened. On the third day again when the same food bag of bananas was given him the lion stopped the delivery boy and shouted at him, “Don’t you know I am a lion, the King of the jungle”? What’s  wrong with the management of the zoo? What nonsense is this? Why are you delivering bananas to me? The management boy politely said, “Sir I know you are the king of the jungle”, but you have been brought here on the monkey’s visa!!!

The moral of the story is, better to be a lion in your own country than a monkey elsewhere.

ECAT/MDCAT English Reading Comprehension-II For NED,Mehran UET, GIKI, PIAS, NUST universities of Pakistan

 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.

Difference between Translatory, Rotatory and Vibratory Motion And Some basic Concept that define Motion

 Difference Between Translatory, Rotatory and Vibratory Motion Some Basic Concepts that Define Motion Distance:    The total length covered by a body without mentioning the direction, is called Distance. Its unit is Meter. It is Scalar Quantity. Displacement: The distance measured in a particular direction is said to be Displacement. Its Unit is Meter. It is a vector quantity. Speed: Speed of an object determines how fast the object is moving. The rate of change of the position of an object is called Speed. It is a Scalar quantity. Its Unit is meters/seconds. It can be calculated as: If the body covers equal distance in equal interval of time its speed is said to be Uniform Speed. If a body doesn't cover equal distance in equal interval of time, then its speed is said to be Variable Speed. Velocity: Velocity means the speed of an object in an specified direction. It is the rate of change of displacement with respect to time. It is a vector quantity. Its unit is meters/sec...
