If a satellite travels at constant speed at all points in its orbit, then its path is
1) a circle.
2) an ellipse.
3) a parabola.
It travels at constant speed because
4) the net force acting on the satellite is zero.
5) it is characteristic for a satellite to travel at constant speed in this type of orbit.
6) gravitational force decreases with increasing distance.
7) there is no component of gravitational pull directed along the satellite's path.
8) of inertia.
Answer: 1, 7

Two parallel wires carry the a current I in the same direction. Midway between these wires is a third wire, also parallel to the other two, which carries a current 0.5 I, but in the direction opposite from the first two wires. In which direction are the net forces on the outer wires?
a. Both forces are toward the center wire. b. Since the net forces are zero, there is no direction. c. Both forces are away from the center wire. d. Both forces on the two wires are in the same direction in space.
