I am struggling with getting this question done and need some help solving it, explain and make sure the answer is 100% correct.
When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced; the electron slows down. In the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E� of a photon of radiated light:
Eγ=K−K′��=�−�′,
where K� and K′�′ are the kinetic energies of the electron before and after radiation, respectively.
This kind of radiation is called bremsstrahlung radiation, which in German means "braking radiation" or "deceleration radiation." The highest energy of a radiated photon corresponds to the moment when the electron is completely stopped.
Part A.

1. The universe has a typical temperature of only 3.0 K. If the intensities of light of different frequencies follow a blackbody distribution, then which frequency of light does the universe give off most?
2. A new, extremely precise apparatus has measured momentum (y component) of a certain proton to be: 5 x 10-28 kg m/s with an uncertainty of only 2 x 10-29 kg m/s. If the y-position of the proton is also measured, approximately what is the lowest possible uncertainty with which this measurement can be made?
3. What electrical force does a Uranium nucleus (Z=92) exert on one of its inner electrons, located at a distance of 175 picometers (=1.75 x 10-10m) ?
