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 2001 2002 Sun 244 246.8 248.3 250.4 250.5 250.5 250.5 248.8 251.3 251.7 250.8 Has sunlight brightened overall? No Yes What is the best word to describe the type of relationship? Curved Linear What is the correlation between the year and sun brightness (round your answer to at least two decimal places.)

The power of sunlight reaching each square meter of the Earth's surface on a clear day...

The power of sunlight reaching each square meter of the Earth's surface on a clear day in the tropics is close to 1 000 W. On a winter day in Manitoba, the power concentration of sunlight can be 100 W/m2. Many human activities are described by a power per unit area on the order of 102 W/m2 or less. (a) Consider, for example, a family of four paying $66 to the electric company every 30 days for 615 kWh of...

A scientist wishes to investigate whether exposure to sunlight reduces the amount of time it takes for a particular chemical reaction to take place. There is natural variability in reaction time. Data are recorded for 20 different experiments, 10 instances of reaction time in bright, and 10 instances of reaction time in shade. These are presented in the following table. Experiment Conditions Time Experiment Conditions Time 1 Bright 7.1 11 Shade 7.4 2 Bright 6.2 12 Shade 7.0 3 Bright...

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)...

By considering the genotypes in a single generation (NOT changes in frequencies over time or changes from one generation to the next), how would you show that natural selection is occurring in the Near-Lethal Homozygote (near-lethal recessive) simulation (Hint: think about Hardy-Weinberg Equilibrium).

On a cloudless day, the sunlight that reaches the surface of the Earth has an intensity of about 1.01×103 W/m2. What is the electromagnetic energy contained in 4.3 m3 of space just above the Earth's surface? c = 3.00×108 m/s

Which UV light hits earth's surface at the greatest intensity?

Chapter 22--- As rule-governed behavior changes to contingency-governed behavior, three outcomes are possible, depending on whether the rules were easy or hard to follow. Name an issue with the education system, the health industry, or a business model, and determine what the contingency breakdown is. Then, determine the performance management contingency that would result in a more effective or optimal outcome.

On a clear day the electric field in the atmosphere near the earth's surface is 100 N/C, directed vertically downward. (a) If we adopt the convention that the potential at the earth's surface is 0, what is the potential 492 m above the surface? (b) What is the potential at the top of Pike's Peak, 14,110 ft above sea level? (Hint: Do not assume that the surface in part (a) is at sea level.) Explain.

The epicenter of an earthquake is the point on Earth's surface directly above the earthquakes origin. A seismograph can be used to determine the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake's epicenter. Find the location of the earthquake's epicenter if it is 3 miles away from A(2,3), 4 miles away from B(-5,3), and 5 miles away from C(-1,-2).
