Answer:
Frequency, f = 15 Hz
Explanation:
We have,
Speed of an ocean wave is 45 m/s
Wavelength of a wave is 3 m
It is required to find the frequency of an ocean wave.
Speed of a wave,
, f = frequency of ocean wave

So, the frequency of an ocean wave is 15 Hz.
The force of the air resistance is 4 N.
The given parameters;
- mass of the flower pot, m = 2 kg
- weight of the flower pot, W = 20 N
Let the air resistance = F
Apply Newton's second law of motion to determine the force of the air resistance acting upward to oppose the motion of the pot falling downwards.

Thus, the force of the air resistance is 4 N.
