An airplane is flying 1200 m above the ground at a speed of 200 m/s. It drops a package carrying vaccines for a local community that hits the ground after
traveling a horizontal distance of 3130 m.

As the third plane comes by to make the drop, it has a catastrophic engine failure and the pilot has to eject, throwing him straight up from the plane. Assuming that he undergoes free-fall acceleration until he lands describe what would happen to how far the pilot travels(in relation to 3130 m) and briefly explain your answer.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.

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.)
