Transformers: A transformer is an electrical device that is used to transfer electrical energy from one circuit to another through electromagnetic induction. A transformer is made up of two coils of wire, the primary and secondary, which are wrapped around a common iron core.

When stress and strain were covered in Newton’s Third Law of Motion, the name was given to this relationship between force and displacement was Hooke’s law: (16.1.1) F = − k x. Here, F is the restoring force, x is the displacement from equilibrium or deformation, and k is a constant related to the difficulty in deforming the system.

Stress is of various types as follows: Tensile Stress – When forces pull an object and cause its elongation such as the stretching of a rubber band Compressive Stress – When the forces result in the compression of an object Bulk Stress – When an object is squeezed from all sides like the submarine in the depth of the ocean

Hooke’s law describes the elastic properties of materials only in the range in which the force and displacement are proportional. ( See deformation and flow .) Sometimes Hooke’s law is formulated as F = − kx. In this expression F no longer means the applied force but rather means the equal and oppositely directed restoring force that.

This is the true death of the universe, dubbed the "heat death". The idea comes from the second law of thermodynamics, which states that entropy – a measure of "disorder" or the number of ways a.

EXPERIMENT 1 AIM Use of Vernier Callipers to measure diameter of a small spherical/cylindrical body, measure the dimensions of a given regular body of known massand hence to determine its density; and measure the internal diameter and depth of a given cylindrical objectlike beaker/glass/calorimeter and hence to calculate its volume.

Announcing the winners, the Nobel Prize committee said: “The 2022 physics laureates’ development of experimental tools has laid the foundation for a new era of quantum technology. “Being able to manipulate and manage quantum states and all their layers of properties gives us access to tools with unexpected potential.”
