What is rate of change of displacement called? Velocity is defined as rate of change of displacement. What do you mean by negative displacement? Displacement is quantity which considers magnitude as well as direction. If you move in forward direction with reference to your reference point ( initial position) then the displacement will be positive […]

Which of the following are conservative electric field?
Which of the following are conservative electric field? The conservative nature of electrostatic fields establishes the electrostatic field as a conservative field. This opens the door for conservation of energy and the work-kinetic energy theorem in discussions of electric fields and electric forces. Why is electric field called conservative? The work done to carry a […]

Does rubber hold heat?
Does rubber hold heat? A material that does not let heat and electricity travel through it easily is known as an insulator. In many situations, we want to trap heat and slow down its flow, or stop the flow of electricity and prevent electric shocks. Plastic, rubber, wood, and ceramics are good insulators. What is […]
