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

The Wise Caliph



CRITICAL SUMMARY

Caliph Haroon-ur-Rashid was known and respected for his justice and wisdom. He was a great ruler of Abbasid caliphate. He considered his caliphate a big responsibility. He was too much concerned about the Day of Judgment, when he would be asked of his ruled ones.

He wanted to know about the problem of common people, and for this reason, he used to disguise

Himself as a common man and go through the street of Baghdad. He would mingle with the common people, in order to get firsthand knowledge of their difficulties and complaints. Once, city Qazi was able settle the dispute between a rich man and a beggar, over a horse. He presented this case to the Caliph and told him that both the rich and the beggar were claiming the ownership of the horse. The rich man was well-dressed and appeared to be well to do while the other seemed to be a beggar, as he was in rags. The rich man told the wise caliph that he was riding to the city this morning. The beggar begged him to give ride up to the city gate. He was lame and the rich man pulled him up behind him on the horse. When they reached the city gate, the beggar refused to get down and claimed that he was the owner of the horse.

The beggar knew that people would doubt more on him, that how a man in rag could buy such a precious horse. So keeping this in mind; he first gave the justification that because he bought such a precious horse, he became a beggar. Then he changed the whole story of the rich man and told the caliph that it was he, who was riding the horse, and it was the rich man, who asked to lend him the horse but instead of lending, he let him ride his horse and sat behind. But when he reached the city gate, this rich man told him to get down; as such a fine horse should not belong to a beggar and warned him not to mention this to anyone, as no one would believe him.

The Wise Caliph used an excellent technique to judge the truth. He asked first the beggar and then the rich man to place their hand on the horse. When the beggar touched the horse, it winced as if it did not like the touch of his hand but when the rich man touched the horse, the horse snorted and neighed with pleasure.

The caliph decided that the horse belonged to the rich man and told the beggar that he was a liar and a wicked man who tried to rob an honest and respectable man. The Wise Caliph told the beggar that he deserved severe punishment, but he would be merciful and forgive him, if he begged forgiveness of that gentle man there. The beggar had no option other than to ask forgiveness from the rich man. So when he begged his forgiveness, the rich man not only forgave him but also showed his generosity by giving him a handful of gold coins. This noble action of the rich man pleased everybody in the court.

 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

How one can say or decide whether an object is a planet or not?  Major question that can be or usually asked is “Why Pluto is not a planet? Why it is called a Dwarf Planet? What is a Dwarf planet? How much Dwarf Planets are there in our Solar system?” Well after reading this article, you people are going to become aware of everything you need to know about a planet.  So before moving toward the question let’s learn what a planet is?  A Planet is an astronomical body that orbits around the sun. They should be large enough to be made rounded by their gravitational orbit around the sun.  In 1930 Pluto was discovered by an American astronomer named as Clyde Tombaugh and was 9th planet after Neptune in our solar system till 2006. After 2006 the definition of the planet changed and because of th
