Answer: The correct answer is C.

2/10 is simplified to 1/5, that is the factor that changes.

Answer:

1/25

Explanation:

Coulombs law states that the force of attraction between two charges q and Q is directly proportional to the product of the charges and inversely proportional to the square of the distance r between them.

It is expressed as;.

F = kqQ/r²

If two point charges, initially 2 cm apart, the force between them will be;

F = kqQ/2²

F = kqQ/4 ... (1)

If the charges are now moved to a distance of 10cm apart, the force between them will then become;

F2 = kqQ/10²

F2 = kqQ/100.. (2)

Dividing equation 2 by 1;

F2/F = (kqQ/4)/kqQ/10)

F2/F = kqQ/100 × 4/kqQ

F2/F = 1/25

F2 = (1/25)F

The resulting electric force

between the changes by 1/25 since that serves as the constant of proportionality between the two forces

2. Using examples to describe each term, differentiate
melisa1 [442]

Answer: find the answer in the explanation

Explanation:

Average velocity is the average value of magnitude of initial velocity and final velocity.

If U = initial velocity and V = final velocity, then average velocity can be expressed as

Average velocity = ( U + V )/2

A vehicle who takes 60 minutes to cover 30 miles north and then 30 miles south and end up at the same place, has an average speed of 60 miles divided by 60 minutes, or 1 mile per minute.

Instantaneous velocity is the distance covered in a specific direction per time taken. Instantaneous velocity can be expressed as

Velocity = displacement/ time.

Uniform velocity occurs when we have a constant velocity. That is, when velocity does not change. When a vehicle travels in equal distances in equal intervals of time.
