Asolid 0.6350 kg ball rolls without slipping down a track toward a vertical loop of radius r=0.8950 m.
what minimum translational speed vmin must the ball have when it is a height h=1.329 m above the bottom of the loop in order to complete the loop without falling off the track?
assume that the radius of the ball itself is much smaller than the loop radius r. use g=9.810 m/s2 for the acceleration due to gravity.

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.)
