Answer:
E =17,280 J
Explanation:
Since the voltage drops linearly from 6V to 4V, the average is 5V. The energy delivered is .
V is the average of initial and fianl voltage
A is the current passing
t is the time in which current is passed
E=V*A*t = 5*0.015*(64*3600) = 17,280 J
Answer:
A
Explanation:
Because of the convectional currents
The answer is B. An antitussive will help a cough by deterring the cough reflex.
