The term crest refers to which of the following?
a. the top part of a wave
b. the lowest part of a wave
c. the distance from the top of one wave to the top of the next wave
d. the distance from the rest position of a wave to the top of the wave

The answer is A, the highest part of the wave. I hope my answer helped.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
