Calculate Machine Power
Power is defined as the rate at which work is done or energy is transferred.
Power Formula
The formula to calculate power (\(P\)) is:
\(P = \frac{W}{t}\)
Where:
- \(P\) = Power (in Watts, W)
- \(W\) = Work done (in Joules, J)
- \(t\) = Time taken (in seconds, s)
Given Information
From the question, we have:
- Work done (\(W\)) = 1000 J
- Time taken (\(t\)) = 5 s
Calculation
Substitute the given values into the power formula:
\(P = \frac{1000 \text{ J}}{5 \text{ s}}\)
\(P = 200 \text{ J/s}\)
Since 1 J/s is equal to 1 Watt (W), the power is:
\(P = 200 \text{ W}\)
Conclusion
The machine's power is 200 W, which corresponds to Option D.
