Q. Why is the surface wind always directed at some angle across the sea-level isobars toward lower pressure? Why is the surface wind directed across the sea-level isobars at a greater angle in Madison than over the middle of Lake Michigan?

Q. One recent study has shown that x rays with a wavelength of 0.0050 nm can produce mutations in human cells.

Calculate the energy in eV of a photon of radiation with this wavelength.
