Answer: the rider’s pedal force must be greater than friction and the force of gravity

What is a transverse wave? How do the particles in the medium move in relation to the energy of the wave? Does this wave require

Pani-rosa [81]

A transverse wave is a wave where the particles in the medium move perpendicular (at right angles) to the direction of the source or its propagation (think of a snake slithering through grass) an example of a transverse wave could be a light wave. Light waves for instance don’t need a medium in order to propagate but transverse waves in general do need a medium.
