You are standing on a street corner with your friend. You then travel 14.0 mm due west across the street and into your apartment building. You travel in the elevator 22.0 mm upward to your floor, walk 12.0 mm north to the door of your apartment, and then walk 6.0 mm due east to your balcony that overlooks the street.

Which of the following list the divisions of the geologic time scale in order from longest to shortest

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.)
