You are working as an intern for a meteorological laboratory. you are out in the field taking measurements with a device that measures electric fields. you measure the electric field in the air immediately above the earth's surface to be 119 n/c directed downward. (assume the radius of the earth is 6.37 ✕ 106 m.) (a) determine the surface charge density (in c/m2) on the ground. (b) imagine the surface charge density is uniform over the planet. determine the charge (in c) of the whole surface of the earth. (c) determine the earth's electric potential (in v) due to the charge found in (b). (d) determine the difference in potential (in v) between the head and the feet of a person 1.50 m tall. (ignore any charges in the atmosphere.) v

Alarge truck is moving 22.0 m/s. if it’s momentum is 125,000 kg • m/s, what is the trucks mass

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.
