The brightness of sunlight at the earth's surface changes over time depending on whether the earth's atmosphere is more or less clear. Sunlight dimmed between 1960 and 1990. After 1990, air pollution dropped in industrial countries. Did sunlight brighten? Here are data and scatterplot from Boulder, Colorado, averaging over only clear days each year. (Other locations show similar trends.) The response variable is solar radiation in watts per square meter. Year 1992 1993 1994 1995 1996 1997 1998 1999 2000...

Nuclear fission and electrical energy Electrical energy currently produced by nuclear reactors is derived from the decay of 235 92U, through a process known as nuclear fission, whereby a slow-moving neutron is captured by the 235 92U nucleus, creating 236 92U. The uranium nucleus 236 92U is very unstable, and it will immediately decay into two lighter elements and release neutrons. Some of the neutrons will go on to destabilize other nuclei, creating a chain reaction. During fission reactions the...

The Earth's magnetic field protects us from cosmic rays, which are extremely-high-energy subatomic particles generated by esoteric processes in interesting parts of the universe. To get an idea of how this protection might happen, pretend the earth's magnetic field has a constant value of 5.0 x 10^-5 T (northward) from the ground up to a height of 50 km. (a) Suppose a high-energy proton (charge +1.6 x 10^-19 C, mass 1.67 x 10^-27 kg) hits the top of the earths...

The lifetime of batteries produced are independent with an exponential distribution having a mean of 90 days of continuous use. Consider a random selection of 250 batteries. (a) Find the exact probability that at least 50 of these batteries have a lifetime between 60 and 120 days using a binomial modeling approach. (b) Find the exact probability that at least 50 of these batteries have a lifetime between 60 and 120 days using a Poisson modeling approach. (c) Approximate your...

The composition of the earth's atmosphere may have changed over time. To try to discover the nature of the atmosphere long ago, we can examine the gas in bubbles inside ancient amber. Amber is tree resin that has hardened and been trapped in rocks. The gas in bubbles within amber should be a sample of the atmosphere at the time the amber was formed. Measurements on specimens of amber from the late Cretaceous era (75 to 95 million years ago)...
