A 2.80-µF and a 4.50-µF capacitor are connected in series across a 30.0-V battery. A 6.95-µF capacitor is then connected in parallel across the 2.80-µF capacitor. Determine the voltage across the 6.95-µF capacitor.

The change in pitch of a train's horn as it passes while you are standing still can be explained by

The gravitational acceleration on Earth is 9.8 m/s2. A small marble is dropped to the floor, assume that as the marble falls, the only force exerted on the marble is the force of gravity (there is no air resistance).

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.
