You are on an airplane traveling with a constant velocity at an altitude of 20,000m. what is the acceleration of gravity at that altitude? the earth's radius is 6.37 x 10^6m.. a) 9.81 m/s^2. b) 9.78 m/s^2. c) 9.75 m/s^2. d) 9.72 m/s^2. e) 9.69 m/s^2.

C)

Explanation:

Acceleration of gravity is calculated with the following formula:

Where It is the universal gravitational constant

and M is the mass of the earth:

is the distance from the center of earth wich will be in this case the earth's radius plus the altitude of the airplane:

thus, the acceleration g is:

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

if they have a finite resultant
