The frequency of a wave becomes higher due to the object moving at a fast pace coming towards you with shorter wavelengths (depending on the speed) aka the Doppler Effect.

1.Momentum is conserved
3.Kinetic energy is conserved
6.Object's bounce apart
In perfectly elastic collision, the momentum and kinetic energy of teh colliding molecule is preserved because there is no loss in energy from the collision.
Explanation:
Ideally most collisions are inelastic meaning some energy is lost in the collision mostly as heat energy. This is why in inelastic collisions, the molecules will have a reduced momentum and kinetic energy. An example of an inelastic collision is a bouncing tennis ball on the tennis court. With every bounce, it loses some energy hence its height of bounce after every bounce reduces until the ball stops bouncing.
