700*.135an inventor claims to have developed a heat engine that receives 700 kj of heat from a source at 500 k and produces 300 kj of net work while rejecting the waste heat to a sink at 290 k. is this a reasonable claim?

output work is not possible to have more than 294 kJ value so this is not reasonable claim

Explanation:

As we know that the efficiency of heat engine is given as

now we will have

now we know that efficiency is defined as

So output work is not possible to have more than 294 kJ value

f is prop to m1xm2 double m1 double force

i think it's 35 meters
