Let T be a graph. Suppose there is a unique path between every pair of vertices in T. Prove that T is a tree.

Can I do this using the contraposative? Like Let u,v be in T and since I am assuming T to not be a tree this allows cycles to occur thus the paths must not be unique. Am I on the right track?

Two stationary positive point charges, charge 1 of magnitude 3.20nC and charge 2 of magnitude 2.00nC , are separated by a distance of 42.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed v-final of the electron when it is 10.0cm from charge 1?

A capacitor is connected to an ac generator that has a frequency of 3.2 kHz and produces a rms voltage of 1.3 V. The rms current in the capacitor is 29 mA. When the same capacitor is connected to a second ac generator that has a frequency of 5.1 kHz, the rms current in the capacitor is 86mA. What rms voltage does the second generator produce?
