Radius of Mercury = =
Mass of Mercury =
Distance Satellite above the surface of the Mercury = d = 265,000m
Gravitational Constant =
<h2>_____________________________________</h2><h3>SOLUTION:</h3>
Since the Satellite is orbiting around the Planet Mercury, due to the centripetal force, and Centripetal force is the force that acts towards the center of the circle, Whereas The gravitational force also acts towards the center of the circle thus we can say that Centripetal force is equal or same as centripetal force. So,
Fg is Given by,
Fc is Given by,
Where,
G is Gravitational Constant
is mass of Planet Mercury
is Mass of Satellite
r(small letter) is the distance between the center of the Planet Mercury and the satellite.
V is velocity of satellite
<h2>_____________________________________</h2>
Now,
r can also be written as,
Substitute the variables,
Simplify the equation,
V = 2814
Approximately,
V = 2800

Answer: M = 42.553· kg
Explanation: A orbit where a body remains traveling around a gravitating mass at constant radius is called Circular Orbit. Although in reality the orbit is more like an ellipse, the circular orbit is a good approximation to the real one.
In that system, it is possible to determine the velocity needed to maintain the orbit. The formula is: v = , where:
v is velocity;
G is the gravitational constant( = 6.67·)
M is the mass of the gravitating mass;
r is the distance between the center of the massive object and the orbiting object;
But, this question is asking for the mass M, so, rearraging:
Transforming light-years in metres and dividing by 2 to find the radius:
r = (15.9.461 x 10¹⁵)· = 70.9575
M =
M = 42.553.kg
The mass of the massive object at the center of the ring is 42.553.kg.
Answer:
Taking water and oxygen from Earth is rather expensive and hard to do.
Explanation:
Without water and oxygen, travel to other planets is basically impossible
