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.

Answer:
Absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave; and, as the wave passes through a substance, its amplitude steadily decreases.
Explanation:
Answer:
a:it speed up
b:it should be positive since final
velocity is larger than initial velocity
c:acceleration is approximately 4.5
m/s^2
Explanation:
initial velocity=u=4.47m/s
Final velocity=v=17.9m/s
Time=t=3 seconds
a:the car speed up since the velocity
increased
b:change in velocity is positive
because final velocity is larger than
initial velocity
17.9-4.47=13.43 m/s
c: acceleration=(v-u)/t
acceleration=(17.9-4.47)/3
acceleration=13.43/3
acceleration=4.5 m/s^2
The radiation of the solar rays of the sun can damage and heat up land closer but at the same time cool because of the atmosphere
