At an altitude of 3 times the radius of the Earth, the acceleration due to gravity is
a. g/3.
c. g/27.
b. g/9.
d. not given.
Question 2
Two objects are in circular orbits of different radii around the Sun. Which object has the lowest orbital speed?
a. The one closest to the Sun.
b. The one farthest from the Sun.
c. Once in orbit around the Sun, all objects have the same orbital speed regardless of distance from the Sun. It is the greater radius and greater resulting circumference that causes the object farther from the Sun to take longer to complete an orbit.
d. This cannot be found without knowing the relative masses of the objects.
The open ocean is the most extensive biome on earth.

Atmospheric pressure decreases with increase in altitude.
Normal oxygen sensor frequency is from about one to five times per second.
