Answer #1

volume of sphere = 4r3/3

                          = 4*3.14*(1*10-13)3/3

                         = 4.18*10-39cm3

density = mass/volume

            = 1.67*10-34/4.18*10-39

              = 3.99*104 gm/cm3

                           =

Subtract the mass of the atom from the total mass of the individual particles and convert from atomic mass units to eV. The result is the binding energy of the atom. (We speak of the proton and electron in the atom as still being individual particles, but they are actually not. They form a quantum state that differs from the individual particles.)

Quarks and gluons are fundamental particles that will be discussed in Chapter 44. A proton, which is a bound state of two up quarks and a down quark, has a rest mass of mp=1.67×10−27 kg.mp=1.67×10−27 kg. This is significantly greater than the sum of the rest mass of the up quarks, which is mu=4.12×10−30 kgmu=4.12×10−30 kg each, and the rest mass of the down quark, which is md=8.59×10−30 kg.md=8.59×10−30 kg.
