Answer:
Both the third and fifth answers are correct
The amplitude of a wave can be obtained by measuring the distance from the resting position of the wave to its crest. The resting position is half of the distance from the crest to the trough. Given that the distance between the crest and the trough is 3 meters, the amplitude should be half of that, which is 1.5 meters.
Answer:
The constant movement of the soup in the pot is an example of convection.
Explanation:
Convection is the movement of hot and less-hot particles in a gas or liquid, transmitting heat with that motion. Therefore, the movement of soup that heats up the surface is an example of convection.
