Flux: A rectangular loop of wire that can rotate about an axis through its center is placed between the poles of a magnet in a magnetic field with a strength of 0.40 T, as shown in the figure. The length of the loop L is 0.16 m and its width w is 0.040 m. What is the magnetic flux through the loop when the plane of the loop is perpendicular to the magnetic field?
A. 13 × 10-3 T ? m2
B. 2.6 × 103 T ? m2
C. 0.80 T ? m2
D. 2.6 × 10-3 T ? m2

Answer the following statement true (T) or false (F)
________ used the extensive records of planetary positions measured by ________ to discover that the orbits of the planets are ________.
A. Kepler; Galileo; elliptical B. Kepler; Tycho; elliptical C. Tycho; Kepler; elliptical D. Tycho; Kepler; circular
Two dogs, Rover and Fido, run on a level frictionless surface. Rover runs eastward with a momentum of 24 kg . m/s, and Fido runs northward with momentum 10 kg . m/s. They make a sudden perfectly inelastic collision
What is the magnitude of their combined momentum after the collision? A) 14 kg . m/s B) 34 kg . m/s C) 26 kg . m/s D) It cannot be determined without knowing the masses and velocities of the dogs.
