If you dropped a ball while standing on the surface of mars at what rate would it accelerate toward the ground

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Acamcorder has a power rating of 20 watts. if the output voltage from its battery is 9 volts, what current does it use?
