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.
The coefficient of kinetic friction between a 20 Kg box and the floor is 0.40. How much work does a pulling force do on the box in pulling it 8.0 m at the constant speed? The pulling force is directed 390 above the horizontal.
What is the velocity of the beam of electrons that go undeflected when passing during perpendicular electric and magnetic fields of magnitude 4700 V/m and 3.6×10-3 T, correspondingly.
An electron is released from rest in a uniform electric field and accelerates to the north at a rate of 199m/s2. What is the magnitude of the electric field?
A rookie quarterback throws a football with an initial upward velocity component of 15.33 and a horizontal velocity component of 20.4. Overlook air resistance.
Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration, thereby simulating Earth's surface gravity. This is accomplished using two small rockets, each with 130 thrust that are mounte..

Standing at a crosswalk, you hear a frequency of 520 Hz from the siren of an approaching police car. After the police car passes, observed frequency of the siren is 455 Hz. Establish the car's speeds from these observations.
Find an average magnitude of the induced emf . A bungee jumper, who's mass is 79 kg, jumps from a tall building. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 8.2 s.
The gravitational force between two masses M and m separated by a distance r is 40 N. What is the new force when this distance is halved?
A farmer planted a field of Bt 123 corn and wants to estimate the yield in terms of bushels per acre. He counts 22 ears in 1/1000 of an acre. He determines that each ear has about 700 kernels on average. He also knows that the bushel contains abou..
