4. The ice fish lives under the polar ice cap where the water temperature is -4┬░C. This fish doesn't freeze at that temperature due to the solutes in its blood. The solute concentration of the fish's blood can be related to a sodium chloride solution that would have the same freezing point. What is the minimum concentration of sodium chloride solution that would not freeze at -4┬░C Assume idela behavior and complete dissociation of NaCl.

If the effects of atmospheric resistance are accounted for, a freely falling body has an acceleration defined by the equation $a=9.81\left[1-v^{2}\left(10^{-4}\right)\right] \mathrm{m} / \mathrm{s}^{2}$ where $v$ is in $\mathrm{m} / \mathrm{s}$ and the positive direction is downward. If the body is released from rest at a very high altitude, determine (a) the velocity when $t=5 \mathrm{s}$, and (b) the body's terminal or maximum attainable velocity $(\text { as } t \rightarrow \infty)$

A machine at a post office sends packages out a chute and down a ramp to be loaded into delivery vehicles. (a) Calculate the acceleration of a box heading down a $10.0^{\circ}$ slope, assuming the coefficient of friction for a parcel on waxed wood is $0.100 .$ (b) Find the angle of the slope down which this box could move at a constant velocity. You can neglect air resistance in both parts.
