I think the answer is B but the problem in this part is that the South American plate has moved over time. You see the difference?
It is a hammer because hammers are not examples of a simple machine
Hmmmm...I’m not sure but you will will get the right answer don’t give up!
The answer would be:
The comb gains electrons.
The hair loses electrons.
In chemistry, the charge depends on the electrons and protons. The electron will give negative charge and proton will give the positive charge. Proton is located in the nucleus of the atoms so it won't easily move like electron which located in the orbit in the atoms perimeter. So, ignore the option with the proton.
If the combs become negatively charged, that means it gain some electron. Since something gain electron, that means another thing is losing an electron. That electron comes from the hair.
Answer:
Mechanics is the branch of physics which deals with the motion of objects its causes and effects.
Sub branches
kinematics(deals with motion of objects without studying the cause of its motion)
dynamic(deals with the motion and cause of motion of objects)
