Q1. A space station, in the form of a wheel 131 m in diameter, rotates to provide an "artificial gravity" of 4.00 m/s2 for persons who walk around on the inner wall of the outer rim. Find out the rate of the wheel's rotation in revolutions per minute that will produce this effect.

Q2. A solenoid in MRI is 2.40 m long, 94 cm in diameter, and 1200 turns of superconducting wire. Find a) inductance, b) induced emf in the solenoid while the current in the wire is changing from 0 to 2.5 kA in 30 s.
