An l-c circuit has an inductance of 0.450 h and a capacitance of 0.200 nf . during the current oscillations, the maximum current in the inductor is 1.40 a. part a what is the maximum energy e max stored in the capacitor at any time during the current oscillations?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
