How does Coulomb's law relate to test charges?

Answers

Answer 1

Answer: Coulomb's law relate to test charges whenever the positive charge and the negative charge are placed 1 meters apart inside a vacuum made of air. The force of repulsion between the positive and negative charges are around 9.0x10E9 N.

What is the process by which water dissolves certain minerals in the soil and carries them away?

Answers

The correct answer would be LEACHING. When at first thought, it would seem that it is erosion. Erosion not only eliminates the soil minerals, it also washes everything else and that includes the soil. In a different manner, Leaching can happen when certain minute particles of the minerals are melted and mixes with water. All that is left in the soil will be the bigger particles that are not soluble by water. In this manner, only a soil that cannot properly nourish remains as it is stripped off of minerals.

A boy throws a ball and accidentally breaks a window. The momentum of the ball and all the pieces of glass taken together after the collision is ________ the momentum of the ball before the collision

Answers

A boy throws a ball and accidentally breaks a window. The momentum of the ball and all the pieces of glass taken together after the collision is the same as the momentum of the ball before the collision. I think you forgot to give the choices along with the question. I hope that the answer has come to your great help.

Tyler drives 50km north. Tyler then drives back 30km south. What distance did he cover? What was his displacement?

Answers

When Tyler drives 50 km north and then drives back 30 km south, we have:

1. The distance that he covers is 80 km.

2. Tylor's displacement is 20 km.

1. The distance is a scalar that is given by the sum of the kilometers traveled by Tyler as follows:

$d = d_(1) + d_(2) = 50 km + 30 km = 80 km$

Hence, the distance traveled by Tyler was 80 km.

2. The displacement is a vector that depends on the direction of travel. Takin the north direction as positive we have:

$x = x_(1) + x_(2) = 50 km + (-30 km) = 20 km$

Therefore, Tyler's displacement is 20 km.

I hope it helps you!

Answer:

80 km is distance and 30km north is displacement

Explanation:

distance= 50+30=80km

displacement= 50-20=30

his displacement is 30km north

Suggest why signals to satellites are transmitted as slightly divergent beam and not as a parallel beam.

Answers

I can think of two reasons:

1). EVERY transmitted radio signal is transmitted as
a divergent beam. We don't have the technology to
transmit it as a perfectly parallel beam.
That's a good thing, because ...

2). If it were a perfect pencil-thin parallel beam, then
it would be practically impossible to keep it perfectly
aimed at the satellite.
