Answer:
a) Both have same angular speed
b) Mary has larger linear speed
c) Mary has larger radial acceleration
Explanation:
a) Since Tom and Mary are both on the same merry-go-around, all points on the merry-go-around are subjected to a same angular speed. Therefore, they both have the same angular speed.
b) Linear speed, however, is the product of angular speed and their radius or rotation, aka their distance the the center of rotation. In this case Mary has a larger radius since she's sitting at the outer rim.
c) Radical acceleration is the product of angular speed squared and their radius so again, Mary would have a larger radial acceleration because of greater radius.

Explanation:
F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2
That is one answer.
Also, you can use the fact that N = kg*m/s^2
[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)
Answer:
"the plants had already started growing."
Explanation:
I think this is the answer because the definition of a dependent variable is the variable that is being affected by the change. Since the plants had already started growing BECAUSE of "They ran out of the farmer's compost, so
some of the plants received that compost
when the seeds were planted and other
plants got hardware store compost after
the plants had already started growing."
