<h3><u>Answer;</u></h3>
4. the material the object is made of and the color of light that strikes it
<h3><u>Explanation;</u></h3>
- The color of an object is the wavelength of light that the object reflects, which is determined by the arrangement of electrons in the atoms of the material making the object.
- <em><u>We could therefore say that the color of object depends on or is determined by the material making up the object as this determines the the wavelengths of light the object reflects. Lastly, the color of light source also determines the color of the object.</u></em>

Explanation:
We are given that two particles collide and stick together.
If there is no external force act on the two particles then ,it is inelastic collision.
Inelastic collision: There is some loss of kinetic energy but the momentum is conserved.
According to law of conservation of momentum
Initial momentum=Final momentum
Change in momentum=Final momentum-Initial momentum=0
Change in momentum=
Initial kinetic energy is greater than final kinetic energy.
Change in kinetic energy=Final kinetic energy-kinetic energy=- negative

Hence, option c is true.
c.
=0 and 
Answer:
The two planetary movements are revolution and rotation.
Explanation:
In the vast solar system, planets traverse while also remaining fixated within the system because of gravity. Each planet is unique and so is its movement, but, at the same time, there are two common types of movements.
