Q1. A projectile is launched from Earth's surface at a certain initial velocity at an angle above the horizontal, reaching greatest height after time tmax. Another projectile is launched with the same initial velocity and angle from the surface of the Moon, where acceleration of gravity is one-sixth that of Earth. Neglecting 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?

Q2. A single loop of wire with an area of 0.0900 m2 is in a uniform magnetic field that has an initial value of 3.80 T, is vertical to the plane of the loop, and is decreasing at a constant rate of 0.190 T/s.

a. What emf is induced in this loop?

b. If the loop has a resistance of 0.600 Ω, find out the current induced in loop.
