B. What types of energy conversions took place in your body that allowed you to complete the laboratory activity

See the explanation below

Explanation:

Energy can neither be created nor destroyed but can be transformed from one form to another.

When we eat food the chemical energy in the food is transformed to kinetic energy that enables us to do work in the laboratory

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.

c) up
