A superball is dropped and bounces up and down. The height at A is 1 m.

a. What is the mass of the ball if the velocity at B (just before hitting the ground) is 4.43 m/s? Explain, everything!

b. If the height at C is 0.8 m, what happened to the "other" energy?

c. How much is this "other" energy for a 30 g ball?​

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s. t.p.?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
