The answer is:
All the above
The explanation:
The volume and the temperature and the number of particles will affect the pressure of an enclosed gas.
because according to boyle's law when the temperature constant so the pressure and volume of a gas have an inverse relationship, when temperature is constant.
when:
PV = nRT
when p is the pressure
V is the volume
n is number of moles
T is temperature
from this law we can know that there is a relation between P and V and when n has a relation with the number of particles so:
volume , temperature and number of particles affect the pressure of an enclosed gas.
Quantity of electrical charge is measured in Coulombs.
The symbol is C.
b. C
Answer:
Explanation:
Check the attachment.
By the definition of the simple harmonic motion,
The motion of a particle whose acceleration is
1. Always directed towards the center of the motion.
2. Proportional to the distance from center of the motion.
We get, a ∝ -x
where
a = acceleration
x = distance of the particle from center of the motion
- sign says acceleration is in opposite direction of motion
Check the other attachment for proof of a = -ω²x (or a = -ω²y)
x and y are both use to denote distance from center of the motion

The forces acting on the book (Fn and Fg) are equal. Therefore, the netforce is zero and it is an unbalanced force.
A hammer pounding a nail into a board is an example of Newton’s Third law.
Newton’s third law states that for every action there is an equal and opposite reaction. Meaning, when you hit the hammer on the board the same amount of energy that is going into the board, is going into the hammer. Causing the hammer to bounce off the board.
Hope this helps!
