Answer:

Yes, when an apple falls towards the earth, the apple gets accelerated and comes down due to the gravitational force of attraction used by the earth. The apple also exerts an equal and opposite force on the earth but the earth does not move because the mass of the apple is very small, due to which the gravitational force produces a large acceleration in it (a = F/m) but the mass of the earth is very large, the same gravitational force produces very small acceleration in the earth and we don't see the earth rising towards the apple.

Each of the following statements is related to conductors in electrostatic equilibrium. Choose the words that make each statemen
Alexxandr [17]

Answer:

a) interior,  b) inside,   c) minor

Explanation:

In this exercise you are asked to select the correct words so that the statements have been correct

Electric charges always repel each other when they are of the same sign, in conductors this has the consequence that charges accumulate on the surface and the interior remains without electric charges.  with this we analyze the statements

a) interior

b) inside

c) minor

therefore the phrase would be:

(a) The net charge is always zero ---INTERIOR--- the surface of an isolated conductor.

(b) The electric field is always zero ---INSIDE--- a perfect conductor.

(c) The charge density on the surface of an isolated, charged conductor is highest where the surface is ---MINOR---to)

Which physical phenomenon causes the spherical shapes of raindrops
jeyben [28]

Answer:

Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.

The reason a tennis ball and a solid steel ball will accelerate at the same rate in the absence of air resistance is because why
Tasya [4]

The reason a tennis ball and a solid steel ball will accelerate at the same rate in the absence of air resistance is because the net force to mass ratio is the same for both objects.

<h3>What is air resistance?</h3>

Air resistance is described as the forces that are in opposition to the relative motion of an object as it passes through the air.

The units for the force of air resistance are in Newtons (N).

Air resistance can be gotten by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.

So we can conclude that in the absence of air resistance, the horizontal velocity of the body is unaffected by any other external force as the only force which acts on the ball is gravity.
