    Thin Film Interference: Finding m Value

    For thin film interference, I was wondering how you know what the value of m is for the equations: 2nt/λ=m (destructive) 2nt/λ -1/2=m (constructive)

    CALCULATING TEMPERATURE CHANGE FROM THORIUM DECAY

    Homework Statement Thorium (with half-life T1/2 = 1.913 yr. and atomic mass 228.028715 u) undergoes alpha decay and produces radium (atomic mass 224.020186 u) as a daughter nucleus. (Assume the alpha particle has atomic mass 4.002603 u.) (a) What is the decay constant of thorium? (Note that...

    What is the rate of fission events in the reactor core?

    In this problem, we're going get a rough estimate the amount of uranium fuel it would take if the US received all its electrical power from nuclear power plants. The size of a power plant in normally given as the about of electrical power it can produce when running a full capacity. This...
