Answer:
a) heat flows from the warm plate to the cold one
Explanation:
Heat is an expression of energy, the bodies with more heat mean that they have more energy. In this way, they can share or pass this "excess" of energy to the cold body. Both plates are not in total contact but some part are close enough (they are touching) that the heat can pass from one to the other. Also the heat always need a media to travel, in this case, the air that surrounds the plates is also the media that the heat travels from the hot to the cold one.

Explanation:
The third bright fringe will have m = 3.
The distance of the third bright fringe from the central maximum can be calculated by the formula
On substituting the values, the distance can be calculated as
Final Answer: The distance of the third bright fringe from the central maximum is 0.0179 m.
