Energy is the ability to do work or cause change. There are basically
two main types of energy, kinetic and potential. Potential energy is
energy that is stored. There are various types of stored, or potential
energy. Chemical energy from a battery is a potential form of energy,
elastic energy in a stretched rubber band is a form of potential energy,
but the most commonly referred to form of potential energy in physics
is that of gravitational potential energy. This is energy that is
stored due to an object's position. It is dependent on the mass of the
object, the height of the object above the ground or Earth, and the acceleration due to gravity.
The correct answer is
<span>C) either the pressure of the gas, the volume of the gas, or both, will increase.
In fact, the ideal gas law can be written as
</span>

<span>where
p is the gas pressure
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
We can see that if the temperature T increases, then the term on the right in the equation increases, therefore the term on the left should increase as well. In order for this to be possible, at least one between p and V should increase, or also both of them. Therefore, the correct answer is C.</span>

Answer:
A) F=-20.16×10⁹N
B) if the distance doubles, force is 4 times smaller.
Explanation:
q1=-28C
q2=5mC=0.005C
d=25cm=0.25m
Electrostatic force between charges: F=k×q1×q2/d², where k is a coefficient that has the value k=9 × 10⁹ N⋅m²⋅C^(-2) for air.
Thus:
F=9×10⁹×(-28)×0.005/0.25²
F=-20.16×10⁹N
The minus sign indicates attraction.
If distance doubles, d1=2×d, then we have 4d² at the denominator and the force is 4 times smaller.
