According to the universal law of gravitation everything has a gravitation force because everything has mass not everything has a gravitational force because not everything existed when gravity first existed gravity is uniform across the universe gravity only depends upon the mass of an object

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

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

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above
