A 9-volt battery is connected to a capacitor that stores 4.5 * 10-3 joules of energy. Calculate the amount of charge on the capacitor.

Alpha radiation is another type of radiation. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. They have much less energy than either beta particles of gamma waves.

Why is there always some waste heat in a heat engine?

Rigel has an apparent magnitude of 0.18 and betelgeuse an apparent magnitude of 0.45. what can you conclude from this?

What unit is used for acceleration

Calculate the hang time of an athlete who jumps a vertical distance of 0.75 meter

A car rounds a 75-m radius curve at a constant speed of 18 m/s. a ball is suspended by a string from the ceiling the car and moves with the car. the angle between the string and the vertical is:

Emission of light from an atom occurs when an electron

Which is an example of transfroming potential energy to kinetic

Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that's above the ball.
