Post em.. I'll see what i can do

Fissioning helium would yeild a net

a.neither absorbiton nor realese of energy

b.release of energy

c.absorption of energy

 

[goofyre 10+ year member]

absorbtion of energy is what i got from google

 

[CarsThatGoBoom 10+ year member]

how do you find these on google?

 

[its_bacon12 10+ year member]

the sun is fusion of hydrogen to helium atoms, and that is exothermic. i would imaging the reverse is endothermic

what goofyre said.

next-

Fusing two helium nuclei yeilds a net

a. neither

b.absorption of energy

c.realese of energy

When U-235 undergoes fission, the two nuclei that result have a total of

a.92 protons

b.91protons

c.94 protons

d.93 protons

e.90 protons

that doesnt make sense //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif the atomic number would be 92 of one of the 2 resulting atoms

when uranium emits a beta particle, the result is a?

a.thorium

b.a transuranic element

c.protactinium

d.depends onthe isotope

a nucleon has more mass when it is

a.outside the nucleus

b.inside the nucleus

c.both the same

 

[CarsThatGoBoom 10+ year member]

if carbon were used as nuclear fuel, it would be best

a.either fused or fissioned

b.fused

c.fissioned

 

[CarsThatGoBoom 10+ year member]

a proton has the greatest mass in the nucleus of
