Find the velocity of a water wave in meters per second with frequency 0.87 Hertz and wavelength 6.1 meters.

Velocity of a water wave is 5.307 meters per second.

Explanation:

The velocity of a water wave is found by the product of frequency and wavelength.

Frequency is defined as the rate at which a particular number pf wave oscillations travel per second. It is represented by 'f'.

Wavelength is defined by the distance between two points in between two crests or troughs. It is represented by 'λ'.

Velocity(v) = frequency(f) × wavelength(λ)

From the given data

frequency(f) = 0.87 Hertz per second

wavelength(λ) = 6.1 meters

Substituting the given values

velocity(v) = 0.87 × 6.1

velocity(v) = 5.307 Hertz per second.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
