2. You want to build a solenoid by winding a thin wire around a tube with a diameter of 8.00 cm. You want to be able to store 5.00 J of energy in the solenoid when a current of 1.50 A runs through it. If you wind the wire so that you end up with a coil (or loop) density of 4 coils/min, how long must the solenoid be? a) 98.9 m b)...

3. [1pt] Consider the phase speed of transverse waves on a wire, with the changes listed below. Answer `true' (T), `false' (F), or `cannot tell' (C) to each of the five statements. E.g., if the answer to the first statement is T and to the rest, F, enter TFFFF. If the tension in the wire is doubled, the phase speed of the transverse wave doubles. If the tension is increased and the mass of the wire is decreased (assuming the...
