Suppose you are aboard a rocket that is orbiting Earth in the low, circular orbit shown. If you want to escape from Earth and head to the Moon or Mars along the "escape" path shown, what do you need to do?
A) Fire the rocket engine in your direction of travel, so that you gain speed. B) The only way to end up on the "escape" path is to first return to Earth, then launch your rocket with escape velocity. C) Turn the rocket around, and fire the engine so that you lose speed. D) Throw some excess supplies overboard, so that your rocket becomes less massive.

A battery has an internal resistance Rint. Connecting a wire of negligible resistance between the terminals of the battery draws the maximum current Imax from this battery. If instead a resistor is connected between the terminals, a smaller current is produced. What value resistor placed across the terminals would result in the current produced to be half of Imax?
a. 0.63Rint b. Rint c. 0.50Rint d. 0.37Rint
