Assume: The resistance per length of the wire is 0.096 Ohm/m. The two-loop wire circuit is 77.0043 cm wide and 51.3362 cm high. The wire circuit in the figure is located in a magnetic field whose magnitude varies with time according to the expression B = (0.001 T/s) t and its direction is into the page. When the magnetic field is 0.2 T, find the magnitude of the current through the middle leg PQ of the circuit. Answer in units of μA.

A Federation starship with mass 1.90×10^6 kg) uses its tractor beam to pull a shuttlecraft ( 2.20×10^4 kg) aboard from a distance of 10.0 km away. The tractor beam exerts a constant force of 4.0*10^4 N on the shuttlecraft. Both spacecraft are initially at rest. How far does the starship move as it pulls the shuttlecraft aboard?

A block is placed on the top of a ramp as shown in the figure below. The block is re- leased from rest on the frictionless incline. When the block reaches the flat portion of the table it begins to feel a frictional force with the table characterized by a coefficient of kinetic friction μk.Which of the following statements about the energy and work of the system could NOT be correct? 1. The normal force from the incline does no work on the block. 2. The block’s gravitational potential en- ergy loss is equal to kinetic energy gain as it descends. 3. On the table, friction does work on the block causing it to slow down. 4. Along the incline, the potential energy of the system decreases from its initial value. 5. The sum of the potential energy and the kinetic energy of the block at any point along the entire path of travel is conserved. 6. When the block reaches the bottom of the incline, its kinetic energy reaches a maxi- mum. 7. Along the incline, gravity does work on the block causing it to speed up.
