If a runner's power is 400 W as she runs, how much chemical energy does she convert into other forms in 10 minutes? (You will need to rearrange the Power Equation.)
e=p*t e=400w*600s e=240000
To determine the amount of chemical energy converted into other forms in 10 minutes, we can rearrange the power equation:
Power = Energy / Time
Rearranging the equation, we have:
Energy = Power * Time
Substituting the given values, where the power is 400 W and the time is 10 minutes (which needs to be converted to seconds):
Energy = 400 W * (10 minutes * 60 seconds/minute)
Energy = 400 W * (600 seconds)
Energy = 240,000 J
Therefore, the runner converts 240,000 J of chemical energy into other forms in 10 minutes.
To calculate the amount of chemical energy converted into other forms, we first need to rearrange the Power equation.
The Power equation is given by:
Power = Energy/time
Rearranging the equation, we have:
Energy = Power × time
Given:
Power = 400 W
time = 10 minutes
To convert the time from minutes to seconds, we multiply by 60 since there are 60 seconds in a minute:
time = 10 × 60 = 600 seconds
Now we can substitute the values into the equation and calculate the energy:
Energy = 400 W × 600 seconds
Energy = 240,000 Joules
Therefore, the runner converts 240,000 Joules of chemical energy into other forms in 10 minutes.
