please answer asap <3

The data from the electromagnet experiment suggest some relationships between a cause (the construction of the electromagnet) and an effect (the number of paperclips lifted).

Think about the differences between Magnets A, B, and C. Now, select a question that you could ask to help you understand how the construction of an electromagnet affects its strength.

1) What effect does increasing the number of wraps of wire have on the strength of the electromagnet?

2) Will the magnet pick up other objects?

3) Does the battery need to have energy left in it?

4) Why does the nail pick up paper clips?

1) Compared to a ball thrown at 10 meters per second, which statement describes the change in kinetic energy of a ball of the same mass thrown at 20 meters per second?

2) The kinetic energy of the ball thrown at 20 meters per second is half (½×) the kinetic energy of the ball thrown at 10 meters per second.

3) The kinetic energy of the ball thrown at 20 meters per second is two times (2×) the kinetic energy of the ball thrown at 10 meters per second.

4) The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second.

Answer:

D. 4x as much

Explanation:

The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.

You can also prove this mathematically. The formula for kinetic energy is

[tex]\frac{1}{2}mv^2[/tex]

The question says: constant mass so we can ignore that for now.

(1/2) * 10^2 is (1/2) * 100 = 50

for the 20m/s ball it would be

(1/2) * 20^2 = 400 * 1/2 = 200

Once again, you see that it is 4x

Answer:

It is weird that you put this the computer and tech. But it's (D. The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second. !!
