Aball rolls down from the top of a grassy hill, reaches the bottom of the hill, continues to roll, and then starts to slow down and comes to a stop. what forces caused this ball's motion?

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
