Answer:

Action force and reaction force

Explanation:

According to newton's third laws of motion, the action of a body is always associated with the reaction of the other body.

But these two forces don't act on the same body.

For example,

If a man hits on the wooden board with his fist, he exerts a certain amount of force on the surface of the board. Consider it as action force dented by 'Fa'.

The wooden board exerts a similar force that is equal in magnitude but in the direction opposite to the applied force on his fist. Consider it as action force dented by 'Fr'.

In both cases, the force is acting on different bodies. It is mathematically expressed as

Fa = - Fr

Answer:

The required potential difference is $4.95 \times 10^{4}~V$ .

Explanation:

We know, electric field is nothing but the negative gradiant of potential. Mathematically, in three-dimension,

$\vec{E} = -\vec{\nabla}V$

In one dimension, the magnitude of the electric field is

$E = \dfrac{V}{x}$

where ' $V$ ' is the applied voltage and ' $x$ 'is the distance through which the voltage is applied.

Given, $V = 5.78 \times 10^{5}~N~C^{-1}~ and~ x = 8.56~cm = 0.0856~m$ .

So the required potential difference is

$V = E \times x = 5.78 \times 10^{5}~N~C^{-1} \times 0.0856~m = 4.95 \times 10^{4}~V$

An electric current flows out of the page. What is the direction of the magnetic field?

Mademuasel [1]

<span>When the electric current flows out of the page and the direction of the magnetic field is counter-clockwise. The magnetic field that is made by an electric current is said to be always leaning perpendicularly to the direction of the current flow.</span>

What will be the final velocity of a 5.0 g bullet starting from rest, if a net force of 45 N is applied over a time of 0.02s?

Wewaii [24]

We know there’s a change in momentum due to a force applied over a time interval. Ft= m[v(final)-v(initial)]. Now simply plug in know values: (45)(0.02)=.005[v(final)-0]. Remember converting grams to kilograms. Solve for v final
