Q
Q: If a machine does 500 J of work in 10 seconds, what is its power output?
Solution:
Power is calculated using the formula P = W/t. Here, W = 500 J and t = 10 s. Thus, P = 500 J / 10 s = 50 W.
Steps: 7
Show Steps
Step 1: Understand the problem. We need to find the power output of a machine that does 500 Joules of work in 10 seconds.
Step 2: Recall the formula for power. Power (P) is calculated using the formula P = W/t, where W is work done and t is time taken.
Step 3: Identify the values given in the problem. Here, W (work) is 500 Joules and t (time) is 10 seconds.
Step 4: Substitute the values into the formula. Replace W with 500 J and t with 10 s in the formula P = W/t.
Step 5: Perform the calculation. Divide 500 J by 10 s to find P: P = 500 J / 10 s.
Step 6: Calculate the result. 500 divided by 10 equals 50.
Step 7: State the final answer. The power output of the machine is 50 Watts.
