Question

a piece of cork is floating on water in a small tank because oscillates up and down vertically when small ripples pass over the surface of water the velocity of ripples being 0.21 M per second Wave length 15 M and amplitude 5 M a maximum velocity of piece of copies

Answer 1

For example a fishing float or a cork will simply bob up and down as a water wave passes it – the float does not move along in the direction that the wave is moving. Waves in the sea are quite complicated especially in shallow water. Because of the friction between the water and the sea bed the water particles move in circles and that is why waves 'break' as the depth of the water gets less and less.
