How much time is needed to produce 840 joules of work if 100 watts of power is used?
time = work / power
To determine the time needed to produce 840 joules of work using 100 watts of power, we can use the equation:
Work (in joules) = Power (in watts) * Time (in seconds)
Rearranging the equation to solve for time, we have:
Time (in seconds) = Work (in joules) / Power (in watts)
Plugging in the given values, we get:
Time (in seconds) = 840 joules / 100 watts
Simplifying the expression, we find:
Time (in seconds) = 8.4 seconds
Therefore, it would take approximately 8.4 seconds to produce 840 joules of work using 100 watts of power.
