Below, BIO indicates a problem with a biological or medical focus. Problems labeled EST ask you to estimate the answer to a quantitative problem rather than derive a specific answer. Asterisks indicate the level of difficulty of the problem. Problems with no * are considered to be the least difficult a single * marks moderately difficult problems. Two & indicate more difficult problems.
* For the following processes, choose the Initial and final states and describe the process using the physical quantities Internal energy, work, and heating. Explain why the process is irreversible.

- Championship swimmers take about 22 s and about 30 arm strokes to move through the water in a 50 m freestyle race.a. As shown, a swimmer’s metabolic power is 800 W. If the efficiency for swimming is 25%, how much energy is expended moving through the water in a 50 m race?b. If half the energy is used in arm motion and half in leg motion, what is the energy expenditure per arm stroke?c. Model the swimmer’s hand as a paddle. During one arm stroke, the paddle moves halfway around a 90-cm-radius circle. If all the swimmer’s forward propulsion during an arm stroke comes from the hand pushing on the water and none from the arm (somewhat of an oversimplification), what is the average force of the hand on the water?arrow_forwardProblem 1 A rectangular tank that is 4 feet long, 7 feet wide, and 9 feet deep is filled with a heavy liquid that weighs 60 pounds per cubic foot. In each part below, assume that the tank is initially full. Include correct units. c) How much work is done pumping two-thirds of the liquid out over the top of the tank? d) How much work is done pumping two-thirds of the liquid out of a spout 2 feet above the top of the tank? Note: C does not equal 60,480 lb-ft and D does not equal 80,640 lb-ftarrow_forward55 J of heat energy are transferred to an ideal gas and the gas does 40 J of work. What is the change in thermal energy, in Joules? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed.

How much energy, in joules, do you require from food in a year? Counting all forms of energy (such as gasoline, electricity, and energy for heating), the average person consumes about 350 billion joules of energy each year. Compare this value to the energy needed from food alone. a. What is your average power, in watts? Approximately 121 watts (Round to the nearest whole number as needed.) b. The energy required from food is approximately billion joules per year. (Round to the nearest tenth as needed.)arrow_forwardUsing Thermodynamics and Work, Energy and Power A rubberized sphere contains carbon dioxide. If the initial radius of the sphere is 15cm:a.
