The answer is A because the lighter or heavier the liquid is (in this case it depends) it flows up.
A mechanical wave can only travel through matter.
Answer:
Kinetic energy is energy in motion so therefor if you increase the velocity or in your case speed the kinetic energy also has to increase
Explanation:
Kinetic energy = (1/2)*mass*velocity^2
KE = (1/2)mv^2
KE = (1/2)(478)(15)^2
KE = 53775J
