The magnitude of the total displacement is 1000 m
Explanation:
Displacement is a vector quantity connecting the initial position and final position of motion of an object.
The magnitude of the displacement is therefore the distance in a straight line between the initial and final position of motion.
The person in the problem has the following motions:
500 meters due east
866 meters due north
The two motions are perpendicular to each other, so they form the sides of a right triangle, of which the hypothenuse corresponds to the magnitude of the total displacement.
Therefore, the magnitude of the displacement can be simply found by using Pythagorean's theorem:

Answer:
The force of gravitational attraction between the satellite and Earth is newtons.
Explanation:
Statement is incorrect. Correct statement is:
<em>A satellite (</em><em>) travels in orbit around the Earth at a distance of </em>
<em> above Earth's surface. What is the force of gravitational attraction between the satellite and Earth?</em>
The gravitational force experimented by the satellite (), in newtons, is calculated by Newton's Law of Gravitation, whose equation is defined by following formula:
(1)
Where:
- Gravitational constant, in cubic meters per kilogram-square second.
- Mass of the satellite, in kilograms.
- Mass of the Earth, in kilograms.
- Distance of the satellite with respect to the center of the Earth, measured in meters.
If we know that ,
,
and
, then the force of gravitational attraction between the satellite and Earth is:
The force of gravitational attraction between the satellite and Earth is newtons.
