# Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i. e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i. e. include the distance traveled to the first encounter)

As a scuba diver descends under water, the pressure increases. at a total air pressure of 2.51 atm and a temperature of 25.0 ∘c, what is the solubility of n2 in a diver's blood? [use the value of the henry's law constant k calculated in part a, 6.26×10−4mol/(l⋅atm).]assume that the composition of the air in the tank is the same as on land and that all of the dissolved nitrogen remains in the blood. express your answer with the appropriate units.

Air is first compressed adiabatically from 100 kpa and 300 k to 1500 kpa and a specific volume of 0.1m^3/kg. the air is then cooled at constant volume back to 300 k. a) draw and label the processes on a p-v diagram. b) determine the work per unit mass from state 1 to state 2. c) determine the heat per unit mass from state 2 to state 3. d) list the mandatory assumptions to solve this problem.
