Kirsin is learning about the outer planets what else would she know about a planet that is the second largest gas giant and has
the largest rings?
1 answer:
Answer: <u>Saturn is the second largest gas giant and has the largest rings.</u>
Explanation:
- Saturn is the 2nd largest planet in the solar system after Jupiter.
- It is the 6th planet from the Sun and located between Jupiter and Uranus.
- Saturn was named after "Saturnus", the roman god of agriculture.
- Saturn orbital period to move around sun is 29 and half earth years
- Saturn is called gas giant because it is not made of any solid material but light gases (hydrogen and helium).
- Saturn has largest rings. These are made up of pieces of ice, rocks and dust.
- The diagram is attached below:

Answer:
a)
b) I =
c) N*m
d) a =
e) W= 0.25 rad/s
Explanation:
a) we know that:
where is the ubicaton of the center of mass,
the mass of the first rocket,
its distances with the rocket 1,
the mass of the second rocket and
its distance with the rocket 1. So, replacing values, we get:
So, the center of mass is at 60m from the rocket 1.
b) we know that:
where I is the moment of inertia, is the mass of the rocket 1,
its distance from the center of mass,
the mass of the second rocket and
the distance between the rocket 2 and the center of mass. So, replacing values, we get:
I =
c) We know that:
T = Fr
where T is the net torque, F is the force and r is the distance between the rocket and the radius. Then:
Replacing values, we get:
50,000N(60m)+50,000N(30m) = T
N*m
d) We know that:
T = Ia
where T is the net torque, I the moment of inertia and a is the angular aceleration. So, replacing values, we get:
solving for a:
a =
e) Finally, using:
W = at
where W is the angular velocity, a is the angular aceleration and t is the time.
Then, replacing values. we get:
W = ()(30s)
W = 0.25 rad/s
