50 N/cm^2. It is 75+525/4x3. Pls mark me brainliest
Answer:The electrical current through the wires itself causes the home wiring to heat up. This is because as the electrons flow they come across the resistive forces of the medium's material, releasing energy that is expended in the form of heat energy
Explanation:
Answer:
Explanation:
The work-energy theorem states that the work done on the system is equal to its change of kinetic energy: . This refers to the center of mass in the case of a system of particles. To calculate this work, we need to use the net Force on the system and the displacement of its center of mass:
1. It produces heat in various parts which means some useful energy is lost as heat.
<span>2. More power has to be supplied due to the losses.
