A baseball player hits a pop up that launches 45m vertically in the air. If a baseball has a mass of 0.145kg. What would be the Gravitational Potential Energy (GPE) of this baseball? 31.04 J
65.25 J
310.35 J
6.53 J

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.

The smallest particle of an element that retains its identity in a chemical reaction. true or false

If 130 j of energy were added to 1 kg of each of the samples listed in the answer choices, which would experience the greatest temperature increase
