Question

An undiscovered planet, many light-years from Earth, has one moon, which has a nearly circular periodic orbit. If the distance from the center of the moon to the surface of the planet is 2.090×10^5 km and the planet has a radius of 3.600×10^3 km and a mass of 7.00×10^22 kg , how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67×10^−11N·m^2/kg^2.

T=___________days

Answer #1

An undiscovered planet, many light-years from Earth, has one
moon which has a nearly circular periodic orbit. If the distance
from the center of the moon to the surface of the planet is 2.07500
× 105 km and the planet has a radius of 3775 km and a mass of 6.40
× 1022 kg, how long (in days) does it take the moon to make one
revolution around the planet. The gravitational constant is 6.67 ×
10-11 N·m2/kg2.

An undiscovered planet, many light-years from Earth, has one
moon, which has a nearly circular periodic orbit. If the distance
from the center of the moon to the surface of the planet is
2.225×105 km and the planet has a radius of 3.150×103 km and a mass
of 7.90×1022 kg , how long (in days) does it take the moon to make
one revolution around the planet? The gravitational constant is
6.67×10−11N·m2/kg2.

An undiscovered planet, many lightyears from Earth, has one moon
in a periodic orbit. This moon takes time TT on average to complete
one nearly circular revolution around the unnamed planet. If the
diameter of the moon's orbit is d,d, calculate the moon's radial
(or centripetal) acceleration ac.
ac=?

a). An asteroid is discovered in a nearly circular orbit around
the Sun, with an orbital radius that is 2.83 times Earth's. What is
the asteroid's orbital period ?, its "year," in terms of Earth
years?
b). An artificial satellite is in a circular orbit ?=390.0 km

1.Zero, a hypothetical planet, has a mass of 4.9 x 1023 kg, a
radius of 3.3 x 106 m, and no atmosphere. A 10 kg space probe is to
be launched vertically from its surface. (a) If the probe is
launched with an initial kinetic energy of 5.0 x 107 J, what will
be its kinetic energy when it is 4.0 x 106 m from the center of
Zero? (b) If the probe is to achieve a maximum distance of...

In
