A solenoid is wound with a single layer of insulated copper wire (of diameter 2.6 mm) and is 3.2 cm in diameter and 1.6 m long. Assume that adjacent wires touch and that the insulation thickness is negligible. What is the inductance per meter for the solenoid near its center?
A 78-kg base runner begins his slide into second base when he is moving at a speed of 4.2 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches base.
