Answer:
d. equal to one-fourth the acceleration at the surface of the asteroid.
Explanation:
The explanation is attached as a picture with this answer
Newton's law of universal gravitation is being used to compare the accelerations at the surface and at the top of the ball's path.
as it can be seen in the explanation that the proportional form of the equation is used because we do not need to necessarily use to final form with "G" for comparison calculations.
As per the given scenario only difference between the two points in the gravitational field is the distance from center of the spherical asteroid, i.e. r.
It is taken 2r for the top is the path. hence we obtain (1/4)g as our answer.

We use only one variable at a time to find the accurate result. We want to see how the result of experiment changes everytime with a single variable.
Answer:
2nd no. positive.... 3rd no. negitive......
Green. This is because chlorophyll reflects the color green, which is why we see it as this color.
