Planetary rings are ice crystals or particles. These particles are numerous and they are small. Jupiter, Saturn, Uranus and Neptune all have rings and are all Jovian planets.

Saturn has big and numerous rings and are visible from Earth. Jupiter's rings are almost invisible and are dusty. Uranus and Neptune have narrow rings but they are very bright and dense and have very thin dust rings in between. Neptune's rings however are more dense than Uranus' and they seem to make arcs rather than complete circles around the planet. 

Gap moons are small moons that orbit within the rings. They cause gaps in the rings because of the gravity of the moons. They push through the ring particles and move them away from each other.

Moons that are further away also affect the rings through resonances. Resonances can launch waves within the rings. Resonances also causes gaps in rings when the moons push on the ring particles repeatedly.

Answer:

<u>radius</u><u> </u><u>is</u><u> </u><u>C</u><u>:</u><u> </u><u>5</u><u>.</u><u>0</u><u> </u><u>m</u>

Explanation:

formular for centripetal acceleration:

a =  \frac{ {V}^{2} }{r}

a is acceleration

V is velocity

r is radius

24 =  \frac{ {11}^{2} }{r}  \\  \\ r =  \frac{ {11}^{2} }{24}  \\  \\ r = 5.0 \: m

When the government sets a price for wheat that is above the equilibrium price, it is imposing a _____.
nalin [4]
<h3><u>Answer</u>;</h3>

Price floor

When the government sets a price for wheat that is above the equilibrium price, it is imposing a<u> price floor</u>.

<h3><u>Explanation</u>;</h3>
  • <u>Price floors prevent a price from falling below a certain level. When a price floor is set above the equilibrium price, quantity supplied will exceed quantity demanded, and excess supply. </u>
  • <u>Price control </u>occurs when the government laws regulate prices instead of letting market forces determine prices.
  • <u>Price ceilings</u> prevent a price from rising above a certain level.

Gwar [14]

Answer:

2. A force of 50 N is applied to the object for a distance of 2.0 m. Assume that object(the mass of the object is 3kg)

was at rest at the beginning, what speed did it achieved because of the work done on it? (Hint:

Calculate the works performed by the force first.)

I figured that is 8.2m/S,I am just not sure can anyone help me i much appreciate it.

A force vector has a magnitude of 599 newtons and points at an angle of 40.8° below the positive x axis. What is the x scalar co
ASHA 777 [7]

Answer:

F_{x}=453.44N

Explanation:

Given data

Force F=599 N

Angle α=40.8°

To find

x scalar component

Solution

The Scalar x component can be found by

F_{x}=FCos\alpha  \\F_{x}=599Cos(40.8)\\F_{x}=453.44N

The Scalar y component can be found by

F_{y}=-FSin\alpha  \\F_{y}=-599Sin(40.8)\\F_{y}=-391.4N
