Two antennas located at points A and B are coherently broadcasting radio waves of frequency, f = 100. MHz. The two antennas are separated by a distance d = 6.00 m, and a person P is initially x = 72 m away from point A along the x-axis. Observer P walks along the x-axis toward antenna A. What is P's distance from A when she first observes fully destructive interference between the two waves? Use units of m.
Name two different groups of people who have been denied their civil rights at some point in U.S. history. Explain what specific types of discrimination they faced and what they did to achieve recognition of their rights. There are more than two such groups, but limit yourself to two.
In reality, the ionosphere-earth capacitor consists of two concentric, spherical surfaces. Assume it is a spherical capacitor consisting of a conducting sphere (the earth) with radius $R_1$, surrounded by a spherical shell (the ionosphere) with inside radius of $R_2$. Following are several possible expressions for the capacitance of this spherical capacitor. Which expression has the correct units for capacitance?\\ $\epsilon_0 \frac{(4\pi R_2^2)(4\pi R_1^2)}{R_2 - R_1}$ \\ $4\pi \epsilon_0 \frac{R_1 R_2}{R_2 - R_1}$ \\ $4\pi \frac{R_1 R_2}{R_2 - R_1}$ \\ $4\pi \epsilon_0 R_1 R_2$ \\ $4\pi R_1 R_2$
