Problem 4: If Darin were to experience equilibrium in problem #3, how much force would have to be acting against him and in what direction?

A woman exerts a horizontal force of 145 N on a box with a mass of 37.2 kg If the box doesn't move, what's the magnitude of the static friction force (in N)?

A loop of wire sits in a uniform magnetic field, everywhere pointing toward you. Due to a changing magnetic flux through the loop, an induced current flows in the wire, clockwise as shown. The area of the loop is 0.660 m^2, and the magnetic field initially has magnitude 0.540 T. Suppose that, over a time period of 1.91 s, the magnetic field changes from its initial value, producing an average induced voltage of 0.149 V. What is the final value of the magnetic field after this time period? 0.680 T 1.262 T 0.971 T 0.194 T

This time the magnetic field maintains a constant value of 0.520 T, and we achieve an induced voltage of 0.176 V over a time period of 1.26 s by keeping the magnetic field fixed but changing the area of the wire loop from its initial value of 0.710 m^2. What is the final value of the loop s area after this time period? 1.136 m^2 0.454 m^2 0.909 m^2 1.704 m^2 JL
