Which describes how radiation moves?

radiation moves from a cooler object to a warmer object

radiation moves from a warmer object to a cooler object

radiation moves from a warm object to an object of the same temperature

radiation moves from a cool object to an object of the same temperature

Radiation happens when heat moves from its source to something else through the form of energy waves, like infrared waves. It is like a heat transfer and the characteristic of heat enables it to move to a cooler object. Hence, radiation moves from a warmer object to a cooler object. 

Radiation moves from a warmer object to a cooler object

Explanation:

Explanation:

Given

Current in the first wire

Current in the second wire

wires are apart

Force per unit length between the current-carrying wires is

Force exerted  by the wires is the same

Put the values

This force will be repulsive in nature as the current is flowing opposite
