In 2017, the United States consumed 97 quadrillion Btu of energy (97 Quad=97x10^15 Btu).
Visualize the number of humans that could be fed with 97 quad of energy. Assume each human eats 10 MJ (megajoules) of energy per day. Compare your answer to the number of people on earth (7.5 billion).

1. According to the U.S. Energy Information Administration (www.eia.gov) the United States consumed 4.151 trillion kWh (kilowatt-hours) of electric energy in 2010. Write this number in correct scientific notation in terms of kWh. 4.151 X 10^12 2. Of this electric energy, 260.2 billion kWh were produced by hydroelectric sources (think water over dams – like Snoqualmie Falls) in 2010. a) Write this number in correct scientific notation in terms of kWh. 2.602 x 10^11 b) What percent of the total...

Q1 According to United Nations, human population reached 7 billion on October 31, 2011. Using this benchmark and an estimated increase of 3 new persons added to the human population every second (i.e., births – deaths = net increase of 3 p/s), calculate the following: a. On what date (day, month, year) in the future will we reach 8 billion? b. What the population was on the day you were born? c. How long it took for our population to...
Case One: Cloud Helps Fight Cancer Each minute one person in the United States dies from cancer—over half a million deaths per year. Thousands of scientists and physicians are working around the clock to fight cancer where it starts—in our DNA. DNA is a molecule present in our cells that carries most of the genetic instructions used in the development, functioning, and reproduction of all known living organisms. The information in DNA is stored as a code made up of...
