The top of a tin can is removed and the empty can is inverted over a pair of billiard balls on a table, as shown in figure 5. for certain combinations of sizes and weights, the configuration shown is stable, but for other combinations, the can tips over when released. it is proposed to set up a demonstration for a temperance lecture by using in sequence a frozen-orange-juice can and a beer can with the same pair of billiard balls. investigate whether tipping will occur for the following sizes and weights: diameter of ball weight of ball diameter of can weight of can with lid removed 0.57 n assume that all the contacts are frictionless orange juice beer 45 mm 2.0n 70 mm 1.0n 45 mm 2.0n 50 mm figure 5

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

Abatter hits a 0.140-kg baseball that was approaching him at 30 m/s and, as a result, the ball leaves the bat at 40 m/s in the reverse of its original direction. the ball remains in contact with the bat for 2.0 ms. what is the magnitude of the average force exerted by the bat on the ball?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
