A ""zero-net energy"" building: A. is built using only natural raw materials B. can last longer than a traditional building C. produces as much as or more energy than it uses D. produces less than half the solid waste of a traditional building E. all of these answer choices are correct

C

produces as much as or more energy than it uses

Explanation:

This implies that the total energy used by the building is equivalent to the energy generated by the site

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.

would be false hope this out
