Bismuth-210 (20bi) (mass = 209.9841049u) has a half life of 5.013 days. this nucleus might decay by either beta-minus or beta-plus processes. some possible products with masses are polonium-209(208.9824158u), polonium-210(209.9828574u), polonium-211(210.9866369u), lead-209(208.9810748u) lead-210(209.984173 lu), lead-211(210.9887315u). polonium has z-84 and lead has z=82 a.) what is the binding energy of the bismuth nucleus? b.) explain which of the listed nuclei are possible decay products. show all products of the reaction that releases the most energy c.) what is the possible range of energies associated with the b- or b* particle that is emitted? (it is one or the other, not both.) how is a range of energies consistent with conservation of energy?

In a steady-flow steam power plant system, two adiabatic high-pressure and low-pressure turbines ane used to generate power. superheated steam enters the high-pressure turbine at 8 mpa and 550°c. the steam expands in the high-pressure turbine to a saturated vapor at 3 mpa. in order to increase the powe generation of the power plant, another steam turbine working in a lower pressure ranges is deployed. the outlet vapor from the first turbine is heated up at a boiler to the temperature of 500 c at the constant pressure of first turbine's outlet (3 mpa). then, the vapor enters the second turbine and produces extra work. the exit conditions of the second turbine are 5o kpa and 90 percent quality. if the total power output of the power plant is 25 mw, determine a) the mass flow rate of the water (kg/s). b) heat transfer rate in the boiler (mw).
