How much energy will a stock tank heater rated at 1790 Watts use in a 24 hour period? 1. 1790 × 24 × 3600 Joules 2. 1790 × 24 × 60 Joules 3. 1790 Joules

Respuesta :

Option 1 is the correct answer.

Explanation:

Power of heater, P = 1790 W

Time used, t = 24 hours = 24 x 60 x 60 = 24 x 3600 s

We have the equation

               [tex]\texttt{Power}=\frac{\texttt{Energy}}{\texttt{Time}}[/tex]

We need to find energy,

Substituting

                 [tex]\texttt{Power}=\frac{\texttt{Energy}}{\texttt{Time}}\\\\1790=\frac{\texttt{Energy}}{24\times 3600}[/tex]

                  Energy = 1790 x 24 x 3600 J

Option 1 is the correct answer.
