A cyclotron with a radius of 1.0 m is to accelerate deuterons to an energy of 12 Mev.
a) what is the required magnetic field ?
b) what frequency is needed for the voltage between the dees ?
c) if the potential difference between the dees averages 22 kV, how many revolutions will the particles make before exiting ?
d) how much time does it take for one deuteron to go from start to exit ?
e) estimate how far it travels during this time ?
A 42 kg pole vaulter running at 11 m/s vaults over the bar. Her speed while she is above the bar is 0.7 m/s. Avoid air resistance, as well as any energy absorbed by pole, and determine her altitude as she crosses the bar.
A monatomic ideal gas containing 7.95 moles at a temperature of 235 K are expanded isothermally from a volume of 1.23 L to a volume of 4.44 L. Calculate the heat flow into or out of the gas
