A lump of putty with a mass of 0.550 kg and a speed of 0.750c collides head-on and sticks to an identical lump of putty moving with the same speed. After the collision the system is at rest. What is the mass of the system after the collision?
A 4 cm diameter loop with resistance 0.18 Omega surrounds a 2 cm diameter solenoid. The solenoid is 15 cm long, has 100 turns, and carries the current shown in the graph. A positive current is cw when seen from the left.
