Question

If we have a cylinder of uniform solid material and do experiment on it in the lab, then rotate it full turn exactly about its axis, what will be see in experiments repeated again?

select all that apply

a.		No change in the outcome, other than usual measurement error.
b.		Conservation of angular momemtum if we include the system performing the rotation with the cylinder itself.
c.		Complete rotational symmetry, the same physical laws seen in both cases.
d.		The need to apply a torque to perform the rotation.
