Of course, the resistances you chose are just nominal. Given that they are only guaranteed to have resistances within 10% of the nominal value, what is the largest and smallest value that IL may have?

RS (in Ohms):

RL (in Ohms):

ILmax (in Amps):

ILmin (in Amps):

**FLu**, Thursday, March 28, 2013 at 5:15amRS (in Ohms): 100000

RL (in Ohms): 150000

ILmax (in Amps): 4.4e-5

ILmin (in Amps): 3.6e-5

Type all in at once, it does not accept one by one or errors!

Consider a deuteron in a cyclotron with field strength 0.5T. The deuteron is accelerated twice per rotation by a potential of V=25 kV. (a) If the radius of the cyclotron is 2 meter, what is the maximum energy of the deuteron? Express your answer in Joules (the deuteron mass is 3.34×10−27kg) b)Starting from a negligibly small velocity, how many full rotations does the deuteron need before it reaches this maximum energy? c) What is the time it takes for the deuteron to make one complete rotation when its energy is about 500 keV and when it is about 5 MeV? Ignore possible relativistic effect
