Question 39
A storm cloud and the ground represent the plates of a capacitor. During a storm, the capacitor has a potential difference v =
between its plates and a charge q =
. A lightning strike delivers 1.00% of the energy of the capacitor to a tree on the ground. How much sap in the tree can be boiled away? Model the sap as water initially at 30.08C. Water has a specific heat of c =
? 8C, a boiling point of 1008C, and a latent heat of vaporization l =
(a) f =
(b) ti =
(c) tf =
