Ocean waves are hitting a beach with a frequency of 0.100 Hz. Their average wavelength is 15.0 m. What is their average speed? What is the frequency of a pendulum that is moving at 30 m/s with a wavelength of 0.32 m?

Average speed=1.5 m/s

Frequency of pendulum=93.75Hz

Explanation:

We are given

Frequency,

Average wavelength =

Speed of pendulum,

Wavelength,

We have to find the average speed and frequency of pendulum.

We know that

Speed,

Using the formula

Average speed,

Hence, the average speed =1.5m/s

Frequency,

Using the formula

Hence, the frequency of a pendulum=93.75Hz
