Is the most intensely studied celestial feature. It has also help revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. It is also the closest large star-forming region to Earth. The Orion Nebula is an enormous cloud of gas and dust, is located in our galaxy (Milky Way).
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



Answer:
designing a solution
Explanation:
after knowing & identifying a problem we start putting a solution
Answer:
Explanation:
Given
initial speed of Launch
=53.7 m/s
Range of Projectile =Maximum height of Projectile
Range is given by R
Maximum height is given by 



![\frac{u^2\sin \theta }{g}\cdot \left [ 2\cos \theta -\frac{1}{2}\right ]=0](https://tex.z-dn.net/?f=%5Cfrac%7Bu%5E2%5Csin%20%5Ctheta%20%7D%7Bg%7D%5Ccdot%20%5Cleft%20%5B%202%5Ccos%20%5Ctheta%20-%5Cfrac%7B1%7D%7B2%7D%5Cright%20%5D%3D0)
as u cannot be zero therefore
