Answer:

Explanation:
Given data:



Let the distance traveled by the object in the second case be 
In the given problem, work done by the forces are same in both the cases.
Thus,





Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
Transverse wave = at right angles to the direction of the motion of the wave
in transverse wave medium particles will move perpendicular to the direction of motion of medium particles
they all are perpendicular to wave always
Longitudinal wave = back and forth in the direction of the motion of the wave
in longitudinal waves medium particles will move in the direction of wave and the motion is always in back and forth type
electromagnetic wave = alternating waves moving at right angles to each other
electromagnetic waves are combination of electric field and magnetic field which oscillates perpendicular to wave as well as they are perpendicular to each other
