Chapter 3 Fossil Fuel Resources and Use 3.1 A person's primary energy needs are supplied exclusively by burning oil (with an energy content of 3.85 × 107 J/L). If a person's average power consumption is 12 kW, how long would it take that person to use one barrel of oil (158.97 liters)? Solution The power 12 kW is the same as energy consumed at a rate of 12,000 J/s. Thus the amount of oil required per second is (12,000 J/s)/(3.85 × 107 J/L) = 3.12 × 10–4 L/s. Thus to consume...

Question 1 Correct 6.00 points out of 6.00 What is the internal energy of 7.91 x 1022 gas molecules at a temperature of 300 K? Select one: a. 164 J b. 109 J c. 44.2 J d. 492 J Question 2 Correct 6.00 points out of 6.00 Because the energy in SHM alternates between kinetic and potential, at some position x, the kinetic energy must be equal to the potential energy. For the general case, an object undergoing SHM with an amplitude A, which of the following is this position? Select on...
