Answer:

Option D

N • m2/C2

Explanation:

The Cuolomb force constant also known as electric force constant, 1/4πε0

is given as a product of force acting in a unit area per square cuolomb hence its unit is Newton squared metre per square cuolomb as represented by N • m2/C2

1. State Newton's third law of motion and write any three applications of it​
Scrat [10]

Answer:

1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun. 2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

An object is attached to a vertical spring and bobs up and down between points A and B. Where is the object located when its kin
gtnhenbr [62]

Answer:

a. at either A or B

Explanation:

Kinetic energy may be defined as the energy of the system or an object which is due to its velocity of the object it possess.

In the context, an object having mass  is attached to spring which is vertical and the object moves up and down due to spring effect between points A and B. Now these points A and B are the extreme points after which the object bounces back.

At point A and B, the velocity of the object becomes zero and hence the kinetic energy of a body varies directly proportional to its velocity.

                  i.e. Kinetic energy $= \frac{1}{2} \text{mass} \times (\text{ velocity})^2$

A polo player hits a ball with a mass of 0.42 kg with a force of 7.35 Newtons.
Serga [27]
Due to the law of conservation of momentum, the force exerted on the mallet is equal and opposite to the force exerted on the ball, so the answer is C.

Which statements accurately describe Ernest Rutherford’s experiment? Check all that apply.
Dimas [21]

Answer:

Option (1), option (4) and option (5)

Explanation:

The main observations of Ernest Rutherford's experiment are given below:

1. most of the positively charged particles pass straight, it means there is an empty space in the atom.

2. Very few positively charged particles retraces their path.

So,

The positively charged particles were deflected because like charges repel, that means they are deflected by protons.

Almost all the positively charge concentrate in a very small part which is called nucleus.
