The four distinct charges' combined potentials make up the potential in the square's center. The amount of the charge and the distance from the charge both affect the potential caused by a point charge.

Therefore, the center's total potential is V=4V1=ks4 q.

<h3>What is a charge?</h3>

Due to the physical characteristic of electric charge, charged material experiences a force when it is exposed to an electromagnetic field. An object that has no net charge is said to be neutral. Classical electrodynamics is the name given to an earlier theory of the interactions of charged particles.

You can have positive or negative electric charges (commonly carried by protons and electrons respectively). opposing charges attract one another whereas similar charges repel one another.

In a basketball game, a player shoots a jump shot. What force actually causes the player to jump into the air? Question 3 option
Julli [10]

Option B is the correct answer.

In a basketball game, a player shoots a jump shot then the floor pushes up on the player.

<h3>Newton's Third Law</h3>

Newton's third law states that when two bodies interact with each other, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

In the given situation, a player shoots a jump shot. It means that the player pushes the floor downward direction.

Newton's third law is applicable in this situation where the player pushes the floor downward direction, at the same time the floor pushes the player upward. The amount of force applied to the floor by the player is equal in magnitude and opposite in direction as compared to the force applied to the player by the floor.

Hence the option B is the correct answer.

To know more about Newton's third law, follow the link given below.

Sonbull [250]
A boy shooting a rubber band across the classroom --> 
Elastic potential energy transformed into kinetic energy 
<span>The initial energy is the energy stored in the muscles of the boy's arm, which is elastic potential energy. This is converted into motion of the rubber, therefore kinetic energy

A child going down a slide on a playground --> </span>Gravitational potential energy transformed into kinetic energy 
On top of the slide, all the energy of the child is gravitational potential energy due to its height with respect to the ground (E=mgh). when it moves down the slide, this is converted into kinetic energy, because the child acquires a speed v (E=1/2 mv^2)
<span>
Rubbing your hands together to warm them on a cold day --> </span>Kinetic energy being transformed into thermal energy <span>
When rubbing hands, we are moving them (kinetic energy), and this energy raises the temperature of the hand's surface (thermal energy)

Turning on a battery operated light --> </span>
Chemical potential energy transformed into radiant energy <span>
A battery works by mean of chemical reactions (chemical potential energy), producing light (so, emitting energy by radiation, i.e. radiant energy)

Using a dc electric motor --> </span> Electrical energy transformed into kinetic energy<span>
A dc electric motor works using  currents (so, electrical energy), and the energy produced can be used for example to accelerate a car (kinetic energy)

Using a gas power heater to warm a room --> </span>Chemical potential energy transformed into thermal energy 
<span>A gas power heater burns gases (so, chemical reaction, i.e. chemical potential energy) to raise the temperature of the room (thermal energy)

Using a hand crank generator to produce electric current --> Kinetic energy transformed into electrical energy
In a hand-crank generator, the handle is being rotated (kinetic energy) in order to produce an electric current (electrical energy)

Using the light in your room that is plugged into the wall --> </span>Electrical energy transformed into radiant energy  
<span>The lamp works by using electrical current flowing into a resistor (electrical energy) and it produces light, so it emits energy by electromagnetic radiation (radiant energy)

An nfl linebacker can go from 0 m/s to 2.5 m/s in 2.5s. What is his acceleration?
dybincka [34]

Answer:

a= 1 m/s^2

Explanation:

a= (Vf-Vi)/t

a=(2.5m/s - 0m/s)/2.5 s

a=2.5 m/s / 2.5 s

a= 1 m/s^2

An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west. It start
drek231 [11]

The total distance that is traveled is 12 inches.

<h3>What is the distance?</h3>

We know that distance is a scalar quantity. The term distance only has to do with the difference between two points. The direction is not taken into cognizance when we are discussing the distance that has been covered.

As we have said that distance is a scalar quantity, it the follows that the process of obtaining the total distance can only be algebraic given that we could directly add all the distance covered by the ant in order to obtain the total distance of the ant.

Now, we can see that the ant starts at the 17-inch mark, crawls to the 21-inch mark, then moves to the 8-inch mark. The total distance covered is obtained from; (21 - 17) + 8 = 12 inches.
