How many times a minute does a boat bob up and down on ocean waves that have a wavelength of 40.0 m and a propagation speed of 5.00 m/s?

n = 7.5 times/minute

Explanation:

Given that,

Wavelength of the ocean wave,

The speed of the ocean wave, v = 5 m/s

To find,

Number of times a minute does a boat bob up and down on ocean waves.

Solution,

The relation between the speed of wave, wavelength and frequency is given by :

f = 0.125 Hz

The number of times per minute the bob moves up and down is given by :

n = 7.5 times/minute

So, its will move up and down in 7.5 times/minute. Therefore, this is the required solution.

like poles repel so keep pushing north to north and repels funny to see this

i would say
