A nucleus whose mass is 3.499612×10^(−25) kg undergoes spontaneous alpha decay. The original nucleus disappears and there appear two new particles:
a He-4 nucleus of mass 6.640678×10^(−27) kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.433132×10^(−25) kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons).
When the alpha particle has moved far away from the new nucleus (so the electric interactions are negligible), what is the combined kinetic energy of the alpha particle and new nucleus?

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
