Question

Write about Joules law of heating??⚡​

Answer 1

1. When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. This is known as Joule's law.the principle that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.

Answer 2

ANSWER−

Force is push or pull acting on a body which tends to change its state of rest or of motion.

It is denoted by "F".

______________________________________

Additional information-

SI unit of force is Newton(N).

C.G.S (centimetre gram second) unit of force is dyne.

The direction in Which the body is pushed or pulled is called direction of the force.

Effects of force -

A force can change the direction of a moving object.

A force can change the shape and size of an object.

A force can change the speed of a moving object.
