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)

Thanks I got it now. =)

Oh these were the atomic masses given: 141Ba 140.914406 u 144Ba 143.92294 u 139Te 138.93473 u 141Cs 140.91963 u 90Kr 90.9234424 u 91Kr 89.9195238 u 92Kr 91.9261528 u 94Zr 93.9063158 u 93Rb 92.92157 u 235U 235.04392 u proton 1.00728 u...

How do you know how many electrons to subtract?

Thank you. I got it now.

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...

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...
