Q1. A toroidal solenoid has a mean radius of 11.0 cm and a cross-sectional area of 5.00 cm2 and is wound uniformly with 100 turns. A second coil with 500 turns is wound uniformly on top of the first. What is the mutual inductance of these coils?
Q2. A 89-kg fullback moving east with a speed of 5.0 m/s is tackled by a 99-kg opponent running north at 3.0 m/s. If the collision is completely inelastic, compute?
Q3. A projectile is launched from Earth's surface at a certain initial velocity at an angle above the horizontal, reaching maximum height after time tmax. Another projectile is launched with the similar initial velocity and angle from the surface of the Moon, where an acceleration of gravity is one-sixth that of Earth. Neglect air resistance (on Earth) and variations in the acceleration of gravity with height, how long does it take the projectile on the Moon to reach its greatest height?
