The united states uses 1.4×1019 j of electrical energy per year. assume, that all this energy came from the fission of 235u, which releases 200 mev per fission event. assume that all fission energy is converted into electrical energy. part a how many kilograms of 235u would be used per year? express your answer to two significant figures and include the appropriate units. m m = nothing nothing request answer part b how many kilograms of uranium would have to be mined per year to provide that much 235u? (recall that only 0.70% of naturally occurring uranium is 235u.) express your answer to two significant figures and include the appropriate units.

From the choices given, the most reasonable estimate is 25.

Step-by-step explanation:

5 sections on the spinner means there is a 1/5 chance of landing on any of the sections each spin.

This means landing on a section labeled 5 should happen 1/5(150) = 30 times.  The closest option to this is 25.
