A Change of Course. Light travels faster through air than it does through a denser substance, such as water or glass.
So, when light rays travel through air and meet the surface of the denser substance, they are suddenly slowed down.
When this happens, the light rays bend.
An atom is the what makes up elements. It is made up of positive particles (protons), negative particles (electrons), and neutrons (no charged particles).
Protons and neutrons are in the center of the atom while electrons hover around.
You cannot predict an atom. This is because it is not anything to guess about -if you know what I mean.
Happy to help!
The answer is A) Water has surface tension.
This is the correct answer because water allows animals and really light items to rest upon the top of the water.
Hope This Helps! If you could mark me as the brainiest answer, that would be amazing. I want others to read this answer and know it is accurate. If you need help with another question, just ask. :)
