Aneutron at rest decays (breaks up) to a proton and an electron. energy is released in the decay and appears as kinetic energy of the proton and electron. the mass of a proton is 1836 times the mass of an electron.1. what fraction of the total energy released goes into the kinetic energy of the proton? express your answer as a percentage. kp/ktot= %i have already tried these answers and they're incorrecta.1/1836b.1/1837c.1873d.99 e.5.44x10^(-4)all are in %, so maybe that's where i'm making my mistake, but i only have one attempt left so be sure of your answer. you very much!

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
