Answer:
0.00712 m
Explanation:
Given:
Charge on first particle (q₁) = 75 nC = 
Charge on second particle (q₂) = 75 nC = 
Force (F) = 1.00 N
Separation (d) = ?
The magnitude of force is given by Coulomb's law which states that, the magnitude of force acting between two charged particles separated by a distance is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
Therefore, the magnitude of force is given as:

Where,
is the coulomb's constant.
Plug in the given values and solve for 'd'. This gives,

Therefore, the distance between the charges is 0.00712 m.

False. A Red Giant evolves from a main sequence star after it commences
Helium fusion and undergoes a great expansion; in the case of our Sun
it would expand to encompass Earth's orbit. Thus, it would have
approximately the same mass (a small amount being expelled in the helium
flash), and vastly greater volume, equating to vastly lower density.
You're welcome :)

It desolves calcium carbonate causing plates to bend and faults to occur. Faults and plates moving cases the formation of caves.

The concept of this problem is the Law of Conservation of Momentum. Momentum is the product of mass and velocity. To obey the law, the momentum before and after collision should be equal:
m₁ v₁ + m₂v₂ = m₁v₁' + m₂v₂', where
m₁ and m₂ are the masses of the proton and the carbon nucleus, respectively,
v₁ and v₂ are the velocities of the proton and the carbon nucleus before collision, respectively,
v₁' and v₂' are the velocities of the proton and the carbon nucleus after collision, respectively,
m(164) + 12m(0) = mv₁' + 12mv₂'
164 = v₁' + 12v₂' --> equation 1
The second equation is the coefficient of restitution, e, which is equal to 1 for perfect collision. The equation is
(v₂' - v₁')/(v₁ - v₂) = 1
(v₂' - v₁')/(164 - 0) = 1
v₂' - v₁'=164 ---> equation 2
Solving equations 1 and 2 simultaneously, v₁' = -138.77 m/s and v₂' = +25.23 m/s. This means that after the collision, the proton bounced to the left at 138.77 m/s, while the stationary carbon nucleus move to the right at 25.23 m/s.
30x30=900
The answer is 900 meters after 30 seconds
