Suppose you throw a baseball (mass of 145 g) in the air with a force of 300 N. What is its acceleration?

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

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?

Positrons are spontaneously emitted from the nuclei of
