A damped LC circuit consists of a 0.16μF capacitor and a 15mH inductor with resistance 1.3Ω . How many cycles will the circuit oscillate before the peak voltage on the capacitor drops to half its initial value?
A boat moves relative to water with a velocity which is n =2 times less than the river flow velocity. At what angle to the stream direction should the boat move to minimize drifting.
When spiking a volleyball, a player changes the velocity of the ball from 4.2m/s to -24m/s along a certain direction. If the impulse delivered to the ball by the player is -9.3kg . m/s, What is the mass of the volleyball?
It takes 16J of energy to move a 0.30-mC charge from one plate of a 15-?F capacitor to the other, How much charge is on each plat
1. Find the order of magnitude of the density of the nucleus of an atom. What does this result suggest concerning the structure of matter? Model a nucleus as protons and neutrons closely packed together. Each has mass 1.67 x10-27kg and radius on the ..
The entropy of an α-ideal gas changes in the following way as a function of temperature and volume: ΔS = nR ln(Vf/Vi) + αnR ln(Tf/Ti) For an adiabatic process, the change in T is determined by the change in V. In this problem you will compute th..
