You have a 195 Ω resistor, a 0.400 H inductor, and a 5.00 µF capacitor. Suppose you take the resistor and inductor and make a series circuit with a voltage source that has voltage amplitude 30.0 V and an angular frequency of 250 rad/s.

A kid at the junior high cafeteria wants to propel an empty milk carton along a lunch table by hitting it with a 3.0 g spit ball.

A charge, Q2 = -15.00×10-6 C, is 14.00 cm to the right of charge Q1 = 14.00×10-6 C. Where can a third charge be placed, along the line connecting Q1 and Q2, such that it experiences no net force (other than ±∞)? Give distances relative

Does a more massive particle gain less kinetic energy than a lighter particle in traversing a given potential difference?

A wave disturbance is described by the function J=(-36T m^2 s^2 k) / [ (30 s y – 40 s z -4 m t)^2 +500 m^2 s^2]
