In a certain series RLC circuit being driven at a frequency of 60.0 Hz, the maximum voltage across the inductor is 2.00 times the maximum voltage across the resistor and 2.00 times the maximum voltage across the capacitor. By what angle does the current lag the generator emf?

The surface area of a pyramid is 57.8 square inches. What is the surface area of a similar pyramid that is twice as large?

Determine whether the statement is true or false. Justify your answer. The set of ordered pairs {(−8, −2), (−6, 0), (−4, 0), (−2, 2), (0, 4), (2, −2)} represents a function.

Find (a) the reference number for each value of t and (b) the terminal point determined by t.

$$t= \frac { 31 \pi } { 6 }$$

A mixture of copper and gold metals that is subjected to electrorefining contains tellurium as an impurity. The standard reduction potential between tellurium and its lowest common oxidation state, $Te^{4+},$ is $\mathrm { Te } ^ { 4 + } ( a q ) + 4 \mathrm { e } ^ { - } \longrightarrow \mathrm { Te } ( s ) \quad E _ { \mathrm { red } } ^ { \mathrm { o } } = 0.57 \mathrm { V }$ Given this information, describe the probable fate of tellurium impurities during electrorefining. Do the impurities fall to the bottom of the refining bath, unchanged, as copper is oxidized, or do they go into solution as ions? If they go into solution, do they plate out on the cathode?

In a random sample of 28 sports cars, the average annual fuel cost was $2929 and the standard deviation was$786. Construct a 90% confidence interval for

$$\mu$$

. Interpret the results. Assune the annual fuel costs are normally distributed.

Simplify. Write answers without negative or zero exponents.

$$\left( u ^ { 4 } + u ^ { 2 } v ^ { 2 } + v ^ { 4 } \right) \div \left( u ^ { 6 } - v ^ { 6 } \right) \cdot \left( u ^ { 2 } - v ^ { 2 } \right)$$

$$\begin{equation*}A=\begin{bmatrix}2&&-3&&1\\4&&0&&-2\end{bmatrix}\end{equation*}$$

Compute

A coal from Texas which has an ultimate analysis (by mass) of 39.25 percent C, 6.93 percent $H_{2},$ 41.11 percent $O_{2},$ 0.72 percent $N_{2},$ 0.79 percent S, and 11.20 percent ash (non-combustibles) is burned steadily with 40 percent excess air in a power plant boiler. The coal and air enter this boiler at standard conditions, and the products of combustion in the smokestack are at $127^{\circ} \mathrm{C}.$ Calculate the heat transfer, in kJ/kg fuel, in this boiler. Include the effect of the sulfur in the energy analysis by noting that sulfur dioxide has an enthalpy of formation of -297,100 kJ/kmol and an average specific heat at constant pressure of $c_{p}=41.7\ \mathrm{kJ} / \mathrm{kmol} \cdot \mathrm{K}.$

In order to gauge the effectiveness of the OHaganBooks.com site, you recently commissioned a survey of online shoppers. According to the results, 2% of online shoppers visited OHaganBooks.com during a one-week period, while 5% of them visited at least one of OHaganBooks.com’s two main competitors: JungleBooks.com and FarmerBooks.com. Use this information to answer. Assuming that visiting OHaganBooks.com was independent of visiting a competitor, what percentage of online shoppers visited OHaganBooks.com but not a competitor?
