Question

4. A new electric hot water heater claims to have dual 4000W copper heating elements. How long will it take to heat up enough water for your shower? P= 2 X 4000 P= 8,000 W dQ= P \times t \to t= dQ/P

long will it take to heat up enough water for your shower?
P= 2 X 4000
P= 8,000 W
dQ= P \times t \to t= dQ/P
