Why does such a small amount it mass turn into so much energy
Because mass is multiplied by 300,000,000(2)

Could natural radioactivity be used to build a bomb
It doesnât generate enough heat /not strong enough
Which particles were scientists using ti split the uranium atoms

Explain the paradox for obtaining energy for nuclear sources
You have to put a lot of energy in to get little energy out of
Whatâs the prob with alpha particles
