Answer:
The Height is H = 70.02 m
Explanation:
We are given that the
Initial length is =
= 
from what we are told in the question the circumference of the circle is =
This means that the Radius would be :
Let C denote the circumference
So

=> 

We are told that 1-meter bar of steel that increases its temperature by 1 degree C will expand
meters
Hence
The final length would be

Where T is the change in temperature
is the Coefficient of linear expansion for steel
let
denote the final length
So
![L_{final} =40000*10^{6} *[1+ 11*10^{-6}]](https://tex.z-dn.net/?f=L_%7Bfinal%7D%20%3D40000%2A10%5E%7B6%7D%20%2A%5B1%2B%2011%2A10%5E%7B-6%7D%5D)

Now the Height is mathematically represented as



To solve this problem it is necessary to use the concepts related to the Gravitational Force and Newton's Second Law, as far as we know:

Where,
G = Gravitational constant
M = Mass of earth (in this case)
m = mass of satellite
r = radius
In the other hand we have the second's newton law:

Where,
m = mass
a = acceleration
Equation both equations we have,

For the problem we have that,
<em>Satellite A:</em>

<em>Satellite B:</em>

The ratio between the two satellites would be,

Solving for a_B,

Therefore the centripetal acceleration of
is a quarter of 
The planets move eastward against the background of fixed stars with the exception of Venus, Uranus and Pluto moving westward as seen in Earth's sky . This apparent retreating movement is called Retrograde motion. It is illusion created by Earth's movement going by outer planets in their respective orbits.
Answer:
t=v/a
Explanation:
Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;
Acceleration =
The change in velocity per unit of time is the acceleration
From this equation;
time =
This expression is analogous to the expression chosen.
Answer:
Planetesimals (Ex, Mercury, Venus , Mars & Earth)
Explanation:
They are known as Planetesimals , They are small in size and have rocky surface. The examples of Planetesimals are Mercury, Venus Mars and Earth.
They are small early planets , which also has gravitational attraction.
