Answer: 0.33 Hz
Explanation: from the question, the distance between two successive crest is wavelength = 20.9m and the ocean rise and fall through one complete cycle every 3.00s which is the period. Hence T = period = 3.00s
Frequency = 1/ period
Frequency = 1/3 = 0.33 Hz

Answer:
The final speed of the two carts is 1 m/s.
Explanation:
let m = 0.5 kg being the mass of the cart moving at an intial speed of v = 4 m/s and M = 1.5 kg is the mass of the cart at rest V = 0 m/s.
then by conservation of linear momentum, the final speed of the objects Vf is:
m×v + M×V = Vf×(M + m)
Vf = [m×v + M×V]/(M + m)
Vf = [(0.5 kg)×(4 m/s) + (1.5 kg)×(0 m/s)]/(1.5 + 0.5 kg)
= 1 m/s
Therefore, the final speed of the two carts is 1 m/s.
I think the correct answer is A mark has greater gravitational potential energy
