h. An expense representing the systematic allocation of an asset's cost over its useful life.

The resolution limit of a microscope is roughly equal to the wavelength of light used in producing the image . Electron microscopes use an electron beam (in place of photons) to produce much higher resolution ima ges, about 0.20 nm in modern instruments. Assuming that the resolution of an electron microscope is equal to the de Broglie wavelength of the electrons used, to what speed must the electrons be accelerated to obtain a resolution of 0.20 nm?

According to the Federal Bureau of Investigation, there is a violent crime in the United States every 22 seconds ( $A B C$ News, September 25, 2007). Assume that the time between successive violent crimes is exponentially distributed.

b. If there has not been a violent crime in the previous minute, what is the probability that there will be a violent crime in the subsequent minute?
