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
Unit 05: Healthy Lifestyle Health Problems Caused by Mosquitoes Malaria: Malaria, Dengue and Chikungunya are spread by mosquitoes. Malaria is caused by plasmodium, a single celled parasite, often transmitted by infected mosquitoes. It infects red blood cells. It can also lead to the severe liver infection. Sometimes the infected red blood cells become “Sticker” than usual and clot easily which can lead to the stoppage of blood flow to the brain causing Cerebral Malaria. Malaria is recognized through high fever with chills, constipation, kidney dysfunction and disorientation. Dengue: There are four types of dengue virus. It can be transmitted by infected mosquitoes, infected human, blood used in a blood transfusion, organ transmission and from mother to the child. The virus attack white blood cells and other antibodies thus affecting the immune system. The death of white blood cells results in the leakage of liquids from the cells, leading to the deficiency of
