Explanation:
Given that,
Radius in which the satellite orbits, r = 6588 km
Solution,
The centripetal force acting on the satellite is balanced by the gravitational force acting between earth and the satellite. Its expression can be written by :
, M is the mass of earth
v = 7782.53 m/s
Let t is the time required to complete one orbit. It can be calculated as :
t = 5318.78 seconds
or
t = 1.47 hour
Therefore, this is the required solution.
According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red.

A tiltmeter is an object to measure small movements.
Answer:
P = 1471500 [Pa]
Explanation:
We must remember that pressure is defined as the relationship between Force over the area.
where:
P = pressure [Pa] (units of pascals)
F = force [N] (units of Newtons)
A = area of contact = 4 [cm²]
But first we must convert from cm² to m²
A = 0.0004 [m²]
Also, the weight should be calculated as follows:
where:
m = mass = 60 [kg]
g = gravity acceleration = 9.81 [m/s²]
Now replacing:
And the pressure:
Because 1 [Pa] = 1 [N/m²]
Answer:
90
