The electron accelerator uses a potential difference to speed up electrons from rest and inject them into the magnetic field of the Helmholtz coil. Use the Work-Energy Theorem to derive an equation for the speed of the electron as it enters the field of the Helmholtz coil in terms of this potential difference. Use Newton's 2 Law to derive an equation for the radius of the uniform circular motion of the electrons once they are in the magnetic field in terms of the magnetic field, the speed of the electrons, their charge and their mass. Using the previous two equations and the given equation of the magnetic field of the Helmholtz coil, derive an equation that relates the radius of the circular path to the current in the Helmholtz coil. Given the equation you developed in the previous question, propose a linear graph you could make in Excel or Logger Pro that would allow you to find the value of em for an electron.

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).
