•• P7 A box of mass 40 kg hangs motionless from two ropes, as shown in Figure 5.65. The angle is 38 degrees. Choose the box as the system. The x axis runs to the right, the y axis runs up, and the z axis is out of the page. 38° Rope 2 Rope 1 Figure 5.65 (a) Draw a free-body diagram for the box. (b) Is dp/dt of the box zero or nonzero? (c) What is the y component of the gravitational force acting on the block? (A component can be positive or negative). (d) What is the y component of the force on the block due to rope 2? (e) What is the magnitude of F? (f) What is the x component of the force on the block due to rope 2? (g) What is the x component of the force on the block due to rope 1?

A circular loop of wire lies in a plane perpendicular to a magnetic field. The magnetic field has a magnitude of 1.3 T and points out of the page as shown in the figure. The radius of the loop is 18 cm and it has a resistance of 3.2 Ω. Find the induced emf in the loop of wire if the magnetic field doubles in magnitude in 1 seconds. What is the induced current in the loop? In which direction is the induced current?
