So u have to use The gravitational law: F = (GmM)/(r^2) because for the first one they are the same distance apart but both masses are twice as big the bottom force is 4 times larger
But for the second one all masses are the same but the bottom is twice as distant so the top is 4 times larger

The population of oak trees in a forest ecosystem is decreasing. The population of squirrels will most likely _____.
kondor19780726 [428]
The answer should be ''Decrease'' to fill in the blank because squirrels usually live in trees and get food from there so without a place to live when its raining and no food to survive, than they would die and lessen their population so that's why decrease is the answer.

what is the magnitude of the compression forces (assumed to be horizontal) acting on both sides of the center board that is sand
Len [333]

F = normal force by each board on each side

W = weight of the board in between acting in down direction = 95.5 N

f = frictional force in upward direction by each board

\mu = coefficient of friction = 0.663

Using equilibrium of force in Upward direction

f + f = W

f = W/2

f = 95.5/2 = 47.75 N

frictional force is given as

f = \mu F

47.75 = (0.663) F

F = 72.02 N
