The force experienced by the foot is 1000 N
Explanation:
We can solve the question by applying Newton's third law, which states that:
<em>"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
</em>
In this situation, we can identify the foot as object A, and the ball as object B.
We are told that the ball experiences a 1000 N force, so the foot exerts a force of 1000 N on the ball (action). As a consequence of Newton's third law, therefore, the ball also exerts an equal and opposite force of 1000 N (reaction) on the foot.
It is important to remember that action and reaction do not act on the same object, so they never appear at the same time in the same free-body diagram (which shows only the forces acting on one object).

If two charges are moved so that the distance between them is reduced
by half, then the forces between them become 4 times as strong.
Ok so if each side is 4.53 cm, we can multiply 4.53 x 4.53 x 4.53 to get the volume (since v= l x w x h). Density equals mass/volume, so
519 g/4.53 cm
114.57 g/cm^3 (since none of the units cancel)
Answer: C) heat
Explanation: As law of conservation of energy applies to all the systems, which says the energy cannot be created nor destroyed, it can only be converted from one form to another.
The light bulb converts electrical energy into light and heat energy.
A) chemical energy is stored in the bonds.
B) Light is a form of electromagnetic radiation.
D) nuclear energy is stored in the nucleus of the atom.
Answer:
speed is defined as distance travelled per unit time
