FFinal answer:
The work done by a patient riding a stationary bicycle with a load of 30 W for 3 minutes is calculated using the equation Work = Power × Time, which results in 5400 J.
Step-by-step explanation:
The question involves the calculation of the work done by a patient riding a stationary bicycle, which is a concept in physics, specifically related to energy transfer and power. To determine the work done during exercise, we need to use the formula Work (W) = Power (P) × Time (t). The power output can be calculated by the provided load of 30 W (watts). Since the patient is exercising for 3 minutes, we need to convert the time into seconds because the standard unit of time in physics for these calculations is seconds.
In this case, 3 minutes equals 180 seconds (3 minutes × 60 seconds/minute = 180 seconds). Therefore, the total work done by the patient while exercising on the bicycle is calculated through the equation W = P × t, which equals 30 W × 180 s, giving us a result of 5400 J (joules). This means that the correct answer for the work done by the patient during a 3-minute exercise on a stationary bicycle at a load of 30 W is 5400 J.
