The equipotential lines round the infinitely long line of charge are concentric circles round the line of charge.
Equipotential lineAn equipotential line is a line in which the electric potential is constant
Since the electric field of an infinitely long line of charge is perpendicular to the line of charge. At a given distance from the infinitely long line of charge, the electric field is constant. The electric field is constant within a circle round the line of charge. This circle round the line of charge is an equipotential line.So, equipotential lines round the infinitely long line of charge are concentric circles round the line of charge.

Determine the electric potential energy for the array of three charges in the drawing, relative to its value when the charges are infinitely far away and infinitely far apart.
Although we do not have the diagram needed to answer this question, we can provide general information in that electrical potential energy is calculated based on the charges and the distance between them.
How do we calculate electric potential energy?This energy can be calculated using the value of the charges along with the distance between them with the formula Energy = [tex]k\frac{q1q2}{r}[/tex] in which q represents the charges whilst r represents the distance of separation. As we can see these values are inversely proportional to one another.
Therefore, we can confirm that we can calculate electric potential energy using the charges and the distance between them, which will be inversely proportional to one another.

A car that weighs 40,000 N is driving down a hill at a constant velocity. If the car’s momentum is 80,000 kg∙m/s, how fast is the car moving?
The velocity of the car is equal to 20 m/s.
Given the following data:
Weight of car = 40,000 Newton.Car’s momentum = 80,000 kg∙m/s.Scientific data:
Acceleration due to gravity = 10 [tex]m/s^2[/tex].To determine the velocity of the car:
How to determine the car's velocity.First of all, we would calculate the mass of the car by using this formula:
[tex]Weight = mg\\\\40000=m \times 10\\\\m=\frac{40000}{10}[/tex]
Mass, m = 4,000 kg.
For the velocity:
Mathematically, momentum is giving by this formula;
[tex]Momentum = mass \times velocity[/tex]
Making velocity the subject of formula, we have:
[tex]Velocity = \frac{Momentum}{Mass}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Velocity = \frac{80000}{4000}[/tex]
Velocity = 20 m/s.

Which phenomenon do solar panels rely on to produce electricity from sunlight?
Answer:
When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.

Answer: If the cue ball strikes a stationary billiard ball straight on, then the cue ball will stop moving after the collision. It will have transferred all of its kinetic energy to the other ball, which will move forward with the same velocity that the cue ball had before the collision.
Explanation:
Box is kicked (given an initial speed), causing it to slide along a level floor. There is friction acting between the box and floor surfaces. What is true about this motion
Answer:
I would assume that the box slows down due to the frictional force between the floor and the box. In addition, the frictional force points opposite of the boxes motion. As we know, the box was given an initial speed, therefore, having an applied force. Hence, we can conclude that the frictional force opposing the motion of the crate is equal to the applied force but acting in the opposite direction. This frictional force is called static friction. When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value.

On average, how many lunar eclipses are there every year?.
Answer:
Three lunar eclipses every year.
Explanation:
A lunar eclipse only occurs during a full Moon, when the Sun, Earth and Moon are all aligned. But despite the Moon only taking 29.5 days to orbit Earth and complete a cycle from full Moon to full Moon, there are only on average about three lunar eclipses every year.

if you are riding on a train that speed past another train moving in a same direction on an adjacent track ti appears that the other train is moving backward why?
Answer:
If you are traveling with a relativity constant velocity, then you will interpret your reference frame as being at rest. Since you are moving faster than the other train, the other train is moving backwards relative to you. Seeing the other train go past your window from front to rear makes it look like the train is going backwards
