Answer #1

Hope this helps.Thank You.

Astronomers are constantly discovering new planets orbiting
nearby stars. In the following scenario, compare the gravitational
force between the planet and its star to the gravitational force
between the Earth and the Sun and enter your result as a decimal
with no units. (For instance, if the gravitational force between
the planet and the star is 1/4 the gravitational force between the
Earth and the Sun, enter 0.250)

a) Your cosmic journey brought you into the vicinity of a
neutron star. In fact, you are orbiting this neutron star at an
orbital distance of 2,184 kilometers. The neutron star has mass of
1.6 solar masses (MSun = 1.99 × 1030
kg).

1. A satellite orbits a planet. The distance between the
satellite and the center of the planet is r. The time it takes the
satellite to complete one orbit is T.
a. Find the speed of the satellite in its orbit, in terms of the
quantities given above. Do not use the law of gravity in part
a.!
b. Find the acceleration of the satellite in its orbit, in terms
of the quantities given above. Do not use the law...

7. Two satellites are moving
around Earth following orbits of the same radius. Satellite 1 has
mass equal to half of mass of satellite 2. We can conclude
that:
Speed of satellite 1 is twice as big as speed of satellite
2.
Speed of satellite 1 is half of speed of satellite 2.
Speed of satellite 1 is the same as speed of satellite 2.
Speed of satellite 1 in fours times speed of satellite 2.
Speed of satellite 1...

Kepler’s Laws of Planetary Motion:
1. A newly discovered exoplanetary system has a planet orbiting
its host star at 50 times the distance from the Earth to the sun.
If the orbital period of the planet is 40 Earth years, what is the
mass of the host star?
2. The mass of the Earth is approximately 6 × 1026
kg. If the moon takes 27 days to orbit the Earth, how far is the
moon from the Earth?
3. A...

The gravitational force of a star on an orbiting planet 1 is
F1. Planet 2, which is four times as massive as planet 1
and orbits at twice the distance from the star, experiences
gravitational force F2.What is the ratio
F2F1? You can ignore the gravitational force
between the two planets.

QUESTION 1
Part 1
Engineers wish to launch a satellite from the surface of the
Moon. What is the minimum speed the satellite must have to escape
the Moon’s gravity – that is, what is the escape velocity at the
surface of the Moon? The Moon has a mass of 7.3x10^22 kg and a
radius of 1.7x10^6 m.
a.
1700 m/s
b.
5.7x10^6 m/s
c.
It depends on the mass of the satellite.
d.
2400 m/s
Part 2
The satellite...

Consider a satellite of mass m in a circular orbit of radius r
around the Earth of mass ME and radius RE.
1.
What is the gravitational force (magnitude and direction) on
the satellite from Earth?
2.
If we define g(r) to be the force of gravity on a mass m at a
radial distance r from the center of the Earth, divided by the mass
m, then evaluate the ratio g(r)/g(RE)to see how g varies with
radial distance. If...
