From the earth, the moon subtends an angle of approximately 0.5°. If the distance to the moon is approximately 240,000 miles, fi
2 answers:
The approximation for the diameter of the moon accurate to the nearest hundred miles is s = +- 2100 miles
<h3>Further explanation </h3>Arc Measure definition is, in a circle, arc degree measure is equal to the measure of the central angle that intercepts the arc. Whereas the arc Length definition is, In a circle, the length of an arc is a portion of the circumference. Where the letter "s" is used to represent arc length.
(Radian Measure and Arc of a Circle).
There is a formula which relates the arc length of a circle of radius, r, to the central angle, θ in radians.
The radian measure θ of a central angle is defined as the ratio of the length of the arc the angle subtends s, divided by the radius of the circle r.
where s = the arc length
= angle in radians
or
So the approximation for the diameter of the moon accurate to the nearest hundred miles is s = +- 2100 miles

Answer
given,
mass of satellite = 545 Kg
R = 6.4 x 10⁶ m
H = 2 x 6.4 x 10⁶ m
Mass of earth = 5.972 x 10²⁴ Kg
height above earth is equal to earth's mean radius
a) satellite's orbital velocity
centripetal force acting on satellite =
gravitational force =
equating both the above equation
v = 5578.5 m/s
b)
T = 14416.92 s
T = 4 hr
c) gravitational force acting
F = 5202 N
