A capacitance C and an inductance L are operated at the same angular frequency. (a) At what angular frequency will they have the same reactance? (b) If L = 5.00 mH and $C=3.50 \mu F$, what is the numerical value of the angular frequency in part (a), and what is the reactance of each element?

What is the relationship between the lines that have $(3,8)$ and $(-6,-16)$ for direction vectors?

An FM radio station has a frequency of $107.9 \mathrm{MHz}$ and uses two identical antennas mounted ut the same elevation, $12.0 \mathrm{~m}$ apart. The antennas radiate in phase. The resulting radiation pattern has a maximum intensity along a horizontal line perpendicular to the line joining the antennas and midway between them. Assume that the intensity is observed at distances from the antennas that are much greater than $12.0 \mathrm{~m}$. (a) At which other angles (measured from the line of maximum intensity) is the intensity maximum? (b) At which angles is it zero?

(a) When you blow across the opening of a partially filled 2 - L plastic bottle, you hear a tone. After pouring some water out of the bottle, you blow across the opening again. Does this tone have a higher frequency, a lower frequency, or the same frequency as the first tone? (b) Choose the best explanation from among the following: A. The same bottle produces the same frequency. B. The greater distance from the top of the bottle to the level of the water results in a higher frequency. C. A lower level of water results in a longer column of air and hence a lower frequency.
