As 1kg of 235U decays calculate the temp change of the mass.

Assuming no energy escapes, find the approximate temperature rise of 1kg of 235U over 1year from decay. Note: No tables or attachments for this problem.

Rutherford Scattering

I am having trouble deciding which formula to use for this particular problem. A nicket target (Z = 28) is bombarded with fast electrons. The minimum electron kinetic energy needed to produce x-rays in the K series is most nearly what?

Synchrotron for fixed target collisions

To achieve an energy of 20TeV, each of the SSC main rings contains approximately 4000 dipole magnets, each 16m long with a field of 7T. This means that over half of the 60mile SSC tunnel is taken up by dipoles. if you were to build a single synchrotron for use in fixed-target collisions of equivalent energy in the center-of-mass (sqrt(s)=40 TeV) and use a similar magnetic design, how long would your tunnel have to be?

Motion of a charged particle in a magnetic field.

I cannot figure out what equations to use or how to set up the following problem. It just seems like there is some data missing that i need. Any insight as to where to start would really help! A radioactive source emits alpha-particles with kinetic energies of 4MeV. What must be the value of an applied magnetic field so that the radius of curvature of the orbit of the alpha-particle is 10cm? Does the answer depend on the kind of medium it is emitted into?

Pi-Meson Decay

I am confused as to how to apply the 10% accuracy in the attached problem. Also, I am not sure how to set up the problem just to get the minimum value.
