In several of the questions you've posted during the past day, we've already said that a wave with larger amplitude carries more energy. That idea is easy to apply to this question.
Answer:
The Moon blocks the suns light from hitting the surface of the earth
the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
Answer:
2 rad/s
Explanation:
For a rotating object, the linear velocity is given by
where 
is the angular velocity and 
is the radius.
The edge has a linear velocity of 10 m/s and the radius at the edge is 5 m.
Answer:
Explanation:
ASSUMING your speed is constant
f₀ = f(v + vo)/(v + vs)
Δf = f approach - f depart
69.5 = (769(343 + vo)/(343 + 0)) - (769(343 - vo)/(343 + 0))
69.5 = 769(2vo/343)
vo = 15.5 m/s
