Answer from: kratose

d.Forces are either attractive or repulsive.

Explanation:

Gravitational force is the attraction force between two point masses which is given by the formula

$F = \frac{Gm_1m_2}{r^2}$

now similarly we know that electrostatic force is the force between two charges which is given as

$F = \frac{kq_1q_2}{r^2}$

now from above equation we can say that

1) Both type of forces will follow inverse square law

2) Both forces have potential energy which will inversely depends on the distance between two particles

3) Both forces depends on either the product of two charges or the product of two masses

So the only difference between two forces is that the gravitational force is only attraction type of force while electrostatic force is attraction and repulsion both type of force.

Answer from: Quest

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this. hope that you like the video and that it explains more in detail to you.

that is the link.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
