The work function of a specific metal is 3.11 eV. Violet light of wavelength 370 nm ejects electrons with a maximum kinetic energy of 0.81 eV from a certain metal. Required:
What is the binding energy of electrons to metal?

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
