Answer:
Pwave
Explanation:
The P wave can move through solid rocks and fluids, like water or the liquid layers of the earth. So yes, P waves is the right answer. I hope I help.

Answer: 200metres per second
Explanation:
The wavespeed of a wave is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V.
Recall that Velocity (V) = Frequency F x wavelength λ
V = F λ
In this case, wavelength (λ)= 20 m frequency = 10 Hz.
Hence, V = F λ
= 20 metres x 10 hertz
= 200 metres per second
Thus, the wave travels at a speed of 200 metres per second
