Explanation:
It's the definition of "Cognitive Dissonance".
Explanation:
In washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into thermal (heat) energy.
20855 turns of wire are on the coil.
<h3>What do you mean by a magnet?</h3>
A substance or thing that creates a magnetic field is called a magnet. The most noteworthy characteristic of a magnet—a force that pulls on other ferromagnetic elements, such as iron, steel, nickel, cobalt, etc.—as well as the ability to attract or repel other magnets—is caused by this invisible magnetic field. An object made of a substance that has been magnetized and produces its own persistent magnetic field is referred to as a permanent magnet. A common example is a refrigerator magnet used to keep notes on the door of the refrigerator. Ferromagnetic materials are those that can be magnetized and are also those that are powerfully drawn to a magnet (or ferrimagnetic).

Answer:
Change in internal energy AU = 40 J
Explanation:
Given:
Amount of heat added = 70 J
Work done = 30 J
Find:
Change in internal energy AU
Computation:
The net thermal conductivity into a process less the net work performed by the system represents the shift in internal energy.
Change in internal energy AU = Q - W
Change in internal energy AU = 70 J - 30J
Change in internal energy AU = 40 J
