HSC Physics Induced emf in a generator

A tutorial sheet on the induced emf in a spinning coil is given below.

1. A coil spins at a constant rate in a uniform magnetic field. At what posiion is the magnetic flux through it a maximum value?
2. A coil spins at a constant rate in a uniform magnetic field. At what position is the induced emf in the coil a maximum value?
3. When a coil spins in a uniform magnetic field the induced current produces its own magnetic field. Does this magnetic field affect the current flowing in the coil?
4. A coil spins at a constant rate in a uniform magnetic field. Is the mechanical power supplied to the coil constant?
5. A coil spins in a radial magnetic field of constant magnitude. Is an emf induced in the coil?

IB Physics When is a real gas most like an ideal gas?

A common question is the departure of the behaviour of a real gas from ideal gas behaviour. A tutorial sheet on this concept follows.

1. Can an ideal gas be liquefied?
2. Do the particles of an ideal gas collide with each other?
3. The thermodynamic temperature of an ideal gas is increased. How does this affect the collision frequency of the particles?
4. At which temperature, high or low, are the particles of an ideal gas more likely to be in the vicinity of each other?
5. At which pressure, high or low, are the particles of an ideal gas more likely to be in the near vicinity of each other?
6. For an ideal gas pV/nT has a constant value for all values of p, V and T. Sketch a graph showing pV/nT versus p for oxygen gas.
