By shining light on other objects.
the objects will attract with each other
when the two objects are rubbed,certain other object are attract to them.

Sound only happens when there is a collision with another object or a vibration from another object, because that is what a sound is. It can only be soft, loud, strong, weak, light, pitched etc. because it was moved by other existing objects. So sound happens when objects collide or become vibrated.
Answer: When you put the balloon on the wall after you rubbed it on the sweater. the balloon would either stick to the wall or repel from the wall depending on what kind of electrons there are on the sweater
when light passes through it you can see the other side. When this happens, we say that the object transmits light
Some of the light is scattered on its journey to the screen. When the light hits the screen, some of it is reflected from the surface. The rest is refracted through the material of the screen. What happens then depends on screen and what is on its other side.
No. A redshift means that the light has lost energy; one way for this to happens is if galaxies or other objects moveaway from us.

collects light from other objects like the moon.

when objects get lighted from other source of light it is known as illumination
The same thing that happens to any other light; some of it is absorbed by the atmospheres and surfaces of the planets while some is reflected back into space. Starlight is too dim to see objects by it.
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
so that any other particle wont interfere in our experiment
