1) waves produced by a motorboat sailing in water has transverse/logitudional waves. plz.....explain?&&&&&&&&&2) if liqiuds do not posess tranvesrse waves then how are they produced after dipping a stone in it?

transverse waves

L?ongitudional waves?.?  ??B??ecause the wave of water propogates paralelly to the medium with the help of the pressure? ?a?n?d? ???d?e?n?s?i?t?y difference and caused compressions and rarefactions inthe medium.....

Transvers and Longitudinal waves both. Just concentrate on the boat motion. A propeller is used to draw the water back. So a longitudinal wave is generated <------> Again it goes laterally deep in to water, causing transverse wave ~~~~~~. Hope this will be clear by now.

Because transverse waves are generated on the surface of water. Inside the water, longitudinal waves are produced due to the vibrations of the rudder.
