Given these operators A=d/dx and B=x², can you measure the expectation
values of the corresponding observables to infinite precision simultaneously?
A glow worm of mass 5.0 g emits red light (650nm) with a power of 0.10W entirely in the backward
direction. To what speed will it have accelerated after 10y if released into free space and assumed to live?
Energy emitted = P(W)-At(s).
Assume the conservation of linear momentum, which means that the loss of a photon imparts an equivalent
momentum in the opposite direction.

Calculate the momentum of an X-ray photon with a wavelength of 0.17nm. How does
this value compare with the momentum of a free electron that has been accelerated
through a potential difference of 5000 volts? (Hint: electron mass, m, = 9.10938 x 10"
