a large peopeller on a cruise ship is able to transform 2,500,000 J of mechanical energy into, 2,000,000 of electrical energy every second. How much termal energy does this propeller waste per second
To find the amount of thermal energy wasted per second, we need to determine the difference between the mechanical energy input and the electrical energy output.
Mechanical energy input: 2,500,000 J
Electrical energy output: 2,000,000 J
Therefore, the amount of thermal energy wasted per second can be calculated as:
Thermal energy wasted = Mechanical energy input - Electrical energy output
= 2,500,000 J - 2,000,000 J
= 500,000 J
Therefore, the propeller wastes 500,000 J of thermal energy per second.
