2) $14:21:35=10:x:25\phantom{\rule{0ex}{0ex}}2:3:5=2:\frac{x}{5}:5\phantom{\rule{0ex}{0ex}}\Rightarrow 3=\frac{x}{5}\phantom{\rule{0ex}{0ex}}\Rightarrow x=3\times 5=15$

3) 2 hours pharmacist packed = 840 pills

1 mint pharmacist packed =$\frac{840}{120}$ pills

=7 pills

47 mints, he packed = $7\times 47$ =329 pills

As part of your work out, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when u push the platform, you compress the springs. You do 80.0G of work when u compress the springs 0.200m from their uncompressed length.

a) What magnitude of force must u apply to hold the platform in this position?

b) How much additional work must you do to move the platform 0.200m farther, and what maximum force must you apply?

A flexible balloon contains 0.375 mol$\mathrm{m}\mathrm{o}\mathrm{l}$ of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7350 cm3$\mathrm{c}{\mathrm{m}}^{3}$ and a temperature of 22.0 ∘C${}^{\circ}\mathrm{C}$. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K${C}_{p}=33.26\phantom{\rule{thickmathspace}{0ex}}\mathrm{J}/\mathrm{m}\mathrm{o}\mathrm{l}\cdot \mathrm{K}$ and γ=4/3$\gamma =4/3$.

What is the total heat Q$Q\text{Q}$ supplied to the gas in the process?

Dayton Power and Light, Inc., has a power plant on the Miami Riverwhere the river is 800 ft wide. To lay a new cable from the plantto a location in the city 2 mi downstream on the opposite sidecosts $180 per foot across the river and $100 per foot along theland.

(a) Suppose that the cable goes from the plant to a point Q on theopposite side that is x ft from the point P directly opposite theplant. Write a function C(x) that gives the cost of laying thecable in terms of the distance x.

(b) Generate a table of values to determin if the least expensivelocation for point Q is less than 2000 ft or greater than 2000 ftfrom point P.
