1 The pet's remains may be buried in the backyard for free or at a pet cemetery for between $500 and $730. 2  Cats and small dogs cost less and burial for large dogs typically costs more. 3  Caskets range from $90 to $145. 4  The pet's remains may be cremated, either by itself of as part of a group.
Answer: C) Neutron Neutron has approx the same mass as a proton. Remember that Proton+neutron= atomic mass. Each neutral atoms has the same number of proton and electrons, but electron's mass is not included in the overall atomic mass, because is too small. BoxingTiger Â· 5 years ago.
Assuming that the neutron mass was close to that of the proton, Chadwick bombarded hydrogen atoms with his produced neutrons to learn the speed of the protons after the collisions. Then setting the neutron speed equal to those proton speeds, he used the above energy expression to get a neutron mass of 938 +/- 1.8 MeV.
