Describe How the frequency of a wave changed s as it's wavelength changes

Suppose you have two cars, and the larger one is twice as massive as the smaller one. If you and a friend push on them so that their acceleration are equal, how must the forces applied to the cars compared?

A boat has a mass of 4040 kg. Its engines generate a drive force of 4660 N due west, while the wind exerts a force of 880 N due east and the water exerts a resistive force of 1400 N due east. Take west to be the positive direction.

Calculate the wavelength and frequency of the radiation emitted by the electronic transition from the 10th to the 9th excited state of hydrogen.

Why do the positions of stars change in the universe?

A hockey player uses a leaf blower to apply a constant force on a hockey puck. The puck accelerates in a straight line across the ice. Then another player applies an equally strong, constant force on the puck in the opposite direction.
