Martha was leaning out of the window on the second floor of her house and speaking to steve. suddenly, her glasses slipped from her nose. the glasses hit the ground in 2.2 seconds. neglecting the effects of air resistance, answer the questions below.
what is the height of the window from the ground?

b. what was the impact velocity of the glasses?

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.)
