a hairdryer uses 1500 W of power. how much time does it take for the hairdryer to use 250,000 J of energy?(unit=s)PLEASE HELP

Respuesta :

Answer:

The answer to your question is: t = 167 s

Explanation:

Power is defined as a rate at which work is done. Its units are Watts (W). Then the formula to calculate Power is:

                                                        [tex]P = \frac{W}{t}[/tex]

Data

Power = P = 1500 W

time = t = ?

Energy = W = 250000 J

Solve equation for time

                                          [tex]t = W / P[/tex]

Substitution

                                          t = 250000 / 1500

Result

                                          t = 166.67 ≈ 167 s
