Respuesta :

The speed of water waves in the sea, which have wavelength 300 m is 21 m/s.

What is speed?

Speed is the distance travelled by an object in per unit time.

Given that, the wavelength of the waves is 300 m

The frequency of the waves is 0.07 hz

To find the speed

By the formula of speed

Speed = frequency × Wavelength

Putting the value in the equation

Speed = 300  × 0.07 = 21

   

Thus, the speed of these waves is 21 m/s
