Question

B

Answer 1

well done

Answer 2

C

Answer 3

good

Answer 4

Im actually not sure about this one

Answer 5

well judging by this chart, both positrons and electrons have 0 mass so neither A nor B would change the mass

between C and D, between fusion and fission, which one do you think might make the mass number go down?

Answer 6

fission because it splits into smaller

Answer 7

good so D is the better choice

Answer 8

Um A

Answer 9

I did a bit of poking around the web and it seems like the issue is temperature and pressure not the material itself which points us towards B

Answer 10

B

Answer 11

good

Answer 12

B

Answer 13

good

Answer 14

C

Answer 15

close but not quite, in the earlier problem we established some of the issues with fusion, currently we only use fission (B)

Answer 16

C

Answer 17

well done

Answer 18

A

Answer 19

uh
honestly kind of stumped on this one, I know that fusion produces less waste than fission, not sure how they both compare to radioactive decay

Answer 20

its alright

Answer 21

if I have to hazard a guess, radioactive decay is much slower so i'd put it at the bottom, then fusion, then fission (B)

Answer 22

Okay Thanks!!! =)
