Explain how the law of conversation of energy can be resolved with the fact that machines allow large object (resistance) to be moved with very little force (effort) pick the best answer

the answers are a and c

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

i think the answer is c hope this
