</span><span>-A galaxy refers to all existing matter, energy, and space that is held together by gravity</span>
In collision of the steel ball and the steel plate, the collision is an inelastic collision and there is loss in the kinetic energy.
<h3>What are collisions?</h3>
Collisions occur when two objects that are moving in the same directions or in different direction meet each other and collide.
There are two types of collisions:
- elastic collision - the kinetic energy is conserved
- inelastic collision - there is a loss in kinetic energy
In the collision of the steel ball and the steel plate, there is loss in the kinetic energy of the steel ball which is converted to sound energy.
In conclusion, the collision of the steel and steel plate is an inelastic collision.

Helping verbs come before the main verb, the main verb in the sentence is repair therefor the helping verb would be could.
Answer:1.55 times
Explanation:
Given
First wavelength
Second wavelength
According wien's diplacement law
where
T=Temperature
Let be the temperatures corresponding to respectively.
Thus object with is 1.55 times hotter than object with wavelength
