A 50-kg toboggan is coasting on level snow. As it passes beneath a bridge, a 20-kg parcel is dropped straight down and lands in the toboggan. If KE₁ is the original kinetic energy of the toboggan and KE₂ is the kinetic energy after the parcel has been added, what is the ratio KE₂/KE₁?
Why is it important to define one standard anatomical position?

4. The conductivity $\sigma$ is related to the diffusion coefficient $\bar{D}$ and the density of states per unit volume (D/AL) by the relation (a) $\sigma = q^2 \frac{\bar{D}}{AL}$ (b) $\sigma = q^2 \frac{\bar{D}}{AL} \frac{1}{\bar{D}}$ (c) $\sigma = \frac{\bar{D}}{AL} \frac{1}{\bar{D}} \frac{1}{q^2}$ (d) $\sigma = \frac{AL}{q^2 \bar{D} \bar{D}}$ (e) none of the above Explain:
Nitrogen gas, initially at 8 bar, expands isentropically in a turbine at 1.5 bar and 150°C. Assuming that nitrogen is an ideal gas with Cp = 7/2R, calculate the work produced by the turbine in J/mol of nitrogen.

5. (10 points) Guppy Population. A 2000-gallon tank can support no more than 150 guppies.\ Six guppies are introduced into the tank. Assume that the rate of growth of the population is\ $\frac{dP}{dt} = 0.0015P(150 - P)$.\ where t is in weeks.\ (a) Find a formula for the guppy population in terms of t.\ (b) How long will it take for the guppies population to be 100? 125?
