Suppose that you were selected for a "Survivor"-type TV show. To help keep your group connected, you suggest that long vines can be tied together and used to transmit signals in cases of emergency. To get the signals to travel faster, you should
A) select lighter vines.
B) increase the tension on the vines.
C) hang weights from the vines at evenly spaced intervals.
D) do all of the above.
E) do (a) or (b) above, preferably both.

Question

Quizplus · Accepted Answer

Both A and B are valid options to increase the speed of signal transmission through the vines. Lighter vines will have less mass to move, and increasing tension will help the energy of the signal travel faster through the stretched vine. However, hanging weights from the vines (option C) would actually slow down the transmission speed by adding more mass to the system. Therefore, either A or B (or both) would be the best choices.
