What average power did she supply? 1) 380 W 2) 560 W 3) 620 W 4) 670 W 5) 730 W

To determine the average power she supplied, you can use the formula for average power, which is typically calculated as the total work done divided by the time taken. However, since the question presents options without specific context or additional details, we can analyze these choices. An interesting fun fact: In physics, understanding power is key in various fields. For instance, knowing how power translates into performance can impact everything from engineering decisions for machinery to personal fitness when calculating metabolic power output during exercise! When it comes to common mistakes in power calculations, a frequent error is neglecting to convert units properly, such as watts to kilowatts or failing to account for time correctly. Always double-check the units to keep your calculations spot-on; it can be the difference between running a marathon and running out of energy!
