In an oscillating LC circuit in which

$$C = 6.00 \mu F$$

, the maximum potential difference across the capacitor during the oscillations is 1.50 V and the maximum current through the inductor is 50.0 mA. What are (a) the inductance L and (b) the frequency of the oscillations? (c) How much time is required for the charge on the capacitor to rise from zero to its maximum value?

For figure, the switch is closed at $t=0$. Given $V_0=0 \mathrm{~V}$. a. Determine the equations for $v_C$ and $i_C$. b. Compute the capacitor voltage at $t=0^{+} 2,4,6,8,10$, and $12 \mathrm{~ms}$. c. Repeat (b) for the capacitor current. d. Why does $225 \mathrm{~V} / 30\ \Omega$ also yield $i\left(0^{+}\right)$?

For the following exercises, condense each expression to a single logarithm using the properties of logarithms. $\log (x)-\frac{1}{2} \log (y)+3 \log (z)$

For this problem, give the exact answer and then an approximation to two decimal places, when appropriate. The length of the hypotenuse of a

$$30 ^ { \circ } - 60 ^ { \circ } - 90 ^ { \circ }$$

triangle is 12 centimeters. Find the length of each leg.

Explain what an antidumping tariff is. What argument might U.S. steelmakers use to get the government to raise the tariff on steel imports?

Consider the following C++ code:

int lowerLimit;

try
{
    cout << "Entering the try block." << endl;
    if (lowerLimit < 100)
        throw exception("Lower limit violation.");

    cout << "Exiting the try block." << endl;
}
catch (exception eObj)
{
    cout << "Exception: " << eObj.what() << endl;
}
cout << "After the catch block" << endl;

What is the output if:

• The value of lowerLimit is 50?

State whether each sentence is true or false. If false, replace the underlined term to make a true sentence. The $\underline{sine}$ of an acute angle in a right triangle is the ratio of the lengths of its opposite leg to the hypotenuse.
