Q. A certain superconducting magnet in the form of a solenoid of length 0.30 m can generate a magnetic field of 13.0 T in its core when its coils carry a current of 105 A. The windings, made of a niobium-titanium alloy, must be cooled to 4.2 K. Find the number of turns in the solenoid.

Q. A rocket is launched at an angle of 53º above the horizontal with an initial speed of 100 m/s. the rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2 . At this time, its engines fail and the rocket proceeds to move as a projectile. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.
