Question

Which of the following photons have the greatest energy?
A. blue light
B. yellow light
C. green light
D. red light
E. ultraviolet

Answer 1

the higher the freq the higher the energy so UV would have the highest energy as it has a higher freq than visible light :)

Answer 2

isnt it ultraviolet right?

Answer 3

yeah it is ultraviolet

Answer 4

can you help me with one more.
Deuterium
A. can become part of a molecule called heavy water.
B. is an isotope of hydrogen.
C. consists of one proton and one neutron.
D. is stable.
E. all of the above

Answer 5

E

Answer 6

thank you

Answer 7

welcome

Answer 8

ONE MORE LOL

Answer 9

If carbon were used as a nuclear fuel, it would best be

well fission is more efficient than fusion

Answer 11

OK WHAT ABOUT THIS ONE I GOT THIS ONE WRONG.

Answer 12

CAN YOU HELP ME WITH THESE ONES I GOT THEM WRONG

A graph of nuclear mass per nucleon for all the elements
A. starts low, peaks, and then slowly decreases.
B. starts high, dips, and then slowly increases.

D. is a straight line.

Answer 13

doesnt it depend on their frequency - for the first one

Answer 17

WHICH ONE?

Answer 18

for the thorium one - but did u say D was wrong?

Answer 19

FOR THE FIRST ONE YAH

Answer 20

well for the graph for the nuclear mass.. it is B

Answer 21

and for the thorium one it is E bcoz there should be 91 protons :)
