Brutus Buckeye is driving East on I-70 at 29.0 m/s when he sees the Nittany Lion mascot driving West on I-70 at 30.5 m/s and waves at him. The Nittany Lion honks his 500 Hz horn as they pass. Assume all travel in this problem happens in a straight line. a. As they travel towards each other, what frequency does Brutus hear.
b. After they pass each other (maintaining their original speeds), what frequency does Brutus hear?
c. All of this honking causes a traffic jam and both cars come to a complete stop 200 m apart. What frequency does Brutus hear now?

Chapter 23, problem 075 the figure shows a geiger counter, a device used to detect ionizing radiation (radiation that causes ionization of atoms). the counter consists of a thin, positively charged central wire surrounded by a concentric, circular, conducting cylindrical shell with an equal negative charge. thus, a strong radial electric field is set up inside the shell. the shell contains a low-pressure inert gas. a particle of radiation entering the device through the shell wall ionizes a few of the gas atoms. the resulting free electrons (e) are drawn to the positive wire. however, the electric field is so intense that, between collisions with gas atoms, the free electrons gain energy sufficient to ionize these atoms also. more free electrons are thereby created, and the process is repeated until the electrons reach the wire. the resulting "avalanche" of electrons is collected by the wire, generating a signal that is used to record the passage of the original particle of radiation. suppose the radius of the central wire is 24 âµm, the inner radius of the shell 2.3 cm, and the length of the shell 14 cm. if the electric field at the shell's inner wall is 2.8 ă— 104 n/c, what is the total positive charge on the central wire?
