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

 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
