What is the percentage difference mass loss between a Helium nucleus and 4 protons?
My math came out to 99% but I think I did something wrong (this assumes the mass for of 4 protons is 6.6792 x 10^-27kg and a the mass of a helium nucleus is 6.6892e x 10^-27kg (Units need to be in kilograms to use with e=mc^2)
Which particle has the largest mass? and How do nuclear decay reactions help explain the difference in the mass of the proton and neutron?
A black hole is a blackbody if ever there was one, so it should emit blackbody radiation, called Hawking radiation. A black hole of mass M has a total energy of MC2, a surface area of 16πG2M2 / c4 and a temperature of hc3 /16π2kGM.
Imagine a black hole in empty space, where it emits radiation but absorbs nothing. As it loses energy, its mass must decrease; one could say it "evaporates." Derive a differential equation for the mass as a function of time, and solve this equation to obtain an expression for the lifetime of a black hole in terms of its initial mass.
