The charge flowing through a light bulb attached to a 12.0-V battery in 13.0 s is 30.0 C.What is the average power supplied by the battery during this process?
A)360 W
B)12.0 W
C)27.7 W
D)5.20 W
E)30.0 W

The formula for average power is P = QV/t, where Q is the charge, V is the voltage, and t is the time. Plugging in the given values, we get:

P = (30.0 C)(12.0 V)/(13.0 s) = 27.7 W

Therefore, the answer is C, 27.7 W.
