A steam engine has been measured to produce 8.6x107 J of work. How long does it take this engine to produce 19,000 W of power? Given: Formula: Rework: Work:

bueno lo siguiente es que yo no sé inglés

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
