Answer: Some conversions from one system of units to another need to be exact, without increasing or decreasing the precision of the first measurement. This is sometimes called soft conversion. It does not involve changing the physical configuration of the item being measured.
Explanation:
Answer:
C. It is the result of diffraction
Explanation:
I just took the test
The mass of a neutron is:
Since we know its speed, we can calculate the neutron's momentum:
The problem says the photon has the same momentum of the neutron, p. The photon momentum is given by
where h is the Planck constant, and
is the photon wavelength. If we re-arrange the equation and we use the momentum we found before, we can calculate the photon's wavelength:
And since we know the photon travels at speed of light c, we can now calculate the photon frequency:
The temperature should be increased, causing the gas to expand and occupy more space.
