Suppose that the spin magnetic quantum number ms had three possible values, rather than two. If that were the case, how many electrons would it take to fill the K shell? Explain.
A dipole is formed by point charges +3.8 micro Coulomb and -3.8 micro Coulomb placed on the axis at (0.45 m, 0) and (-0.45m, 0), respectively. At what positions on the axis does the potential have the value 7.7×105 V? There should be an x1 and an ..
Find the first and second derivative with respect to x of f(x) = (exp(x/a)-exp(-x/a))/2, where exp(x)=e^x is the exponential function.
Two students with vibrating 440Hz tuning forks walk away from each other with equal speeds. How fast must they walk so that they each hear the frequency of 433 from the other fork.
A box is placed on a conveyor belt that moves with a constant speed of 1.05. The coefficient of kinetic friction between box and belt is 0.80. How much time does it take for the box to stop sliding relative to belt.
