Answer:
The Answer is B because the material the object is made of, the position, or the color have absolutely nothing to do with gravitational potential energy
The centripetal acceleration a is 4.32
10^-4 m/s^2.
<u>Explanation:</u>
The speed is constant and computing the speed from the distance and time for one full lap.
Given, distance = 400 mm = 0.4 m, Time = 100 s.
Computing the v = 0.4 m / 100 s
v = 4
10^-3 m/s.
radius of the circular end r = 37 mm = 0.037 m.
centripetal acceleration a = v^2 / r
= (4
10^-3)^2 / 0.037
a = 4.32
10^-4 m/s^2.

charcoal is the correct answer
hope it helps , pls mark me as brainliest
Answer:
Magnetic activity and sunspots are in a proportional relationship.
Explanation:
From the graph, as one increases, so does the other, thus we describe the relationship as proportional.
Other than that, all of your other answers seem correct.
