Kepler's first law - sometimes referred to as the law of ellipses - explains that planets are orbiting the sun in a path described as an ellipse. ... The resulting shape will be an ellipse. An ellipse is a special curve in which the sum of the distances from every point on the curve to two other points is a constan
Answer:
The orbital velocity 
The period is 
Explanation:
Generally centripetal force acting ring particle is equal to the gravitational force between the ring particle and the planet , this is mathematically represented as

=> 
Here G is the gravitational constant with value 
is the mass of with value 
r is the is distance from the center of the to the outer edge of the A ring
i.e r = R + D
Here R is the radius of the planet with value 
D is the distance from the equator to the outer edge of the A ring with value 
So

=> 
So
=> ![w = \sqrt{ \frac{ 6.67*10^{-11}* 5.683*10^{26}}{[1.4*10^{8}]^3} }](https://tex.z-dn.net/?f=w%20%3D%20%5Csqrt%7B%20%5Cfrac%7B%206.67%2A10%5E%7B-11%7D%2A%20%205.683%2A10%5E%7B26%7D%7D%7B%5B1.4%2A10%5E%7B8%7D%5D%5E3%7D%20%7D)

The period is 
Explanation:
Generally centripetal force acting ring particle is equal to the gravitational force between the ring particle and the , this is mathematically represented as

To solve this problem we will apply the Newtonian concept of gravitational acceleration produced by a planet. This relationship is given by:

Where,
G = Gravitational Universal Constant
M = Mass of Earth
r = Radius
The values given are based on the constants of the earth, so they can be expressed as


The relationship of gravity would then be given:

The relationship with the new planet, from the gravity of the earth would be given





The relationship with the weight of the earth would be given as:





Therefore the weigh on this planet would be 96N
We use these objects during day will be actually hands nose eyes
