Two bicyclists ride towards each other along a long straight road, each with a constant speed of 10 km/h. when they are 20 km apart, a bee begins flying from the front of one bicycle towards the other at 30 km/h. when the bee reaches the other bicycle, it immediately turns around and starts flying back towards the original bicycle at the same speed. this repeats until the bikes crash into each other and the bee is squished.
a. how many trips does the bee travel before it gets squished?
b. for how long will the bee survive?
c. what is the total distance the bee will travel?

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?
