Centripetal force of satellite = gravitational force between earth and the satellite
(m•v^2)/r = (G•Me•m)/r^2
v^2 = (G•Me)/r
v^2 = 6.67x10^-11 x 5.598x10^24 / 7.5x10^7
v = 2231 m/s
so answer is B
your answer i believe would be c because light waves, mechanical waves, exc. all carry charged particals.
The mechanical advantage of a machine is the ratio of the force produced by the machine to the force applied to it. Therefore, we may calculate the applied force using:
Mechanical advantage = force by machine / force applied
6 = 2 / force applied
Force applied = 1/3
Thus, the distance that the effort must move will be 1/3 inch
