What is the motion of the particles in this kind of wave?

A. The particles will move up and down over large areas.

B. The particles will move up and down over small areas.

C. The particles will move side to side over small areas.

D. The particles will move side to side over large areas

B) The particles will move up and down over small areas

Explanation:

The above wave is an example of a transverse wave troughs and crests). A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.

The particles of the medium move perpendicular to the direction that the pulse moves.Transverse waves are always characterized by particle motion being perpendicular to wave motion.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
