Answer:
505929 AU
Explanation:
As you may know, one light-year is equivalent to approximately 63241.1 Astronomical Units. To get your answer, simply multiply 63241.1 * 8 to get ≈505929 AU
 
        
             
        
        
        
We might have a trouble viewing the general part of galaxy because :   the Milky Way's center is so brilliant and filled with stars, it has been particularly challenging for astronomers to examine it because it is impossible to distinguish individual stars and clusters.
<h3>What is a Milky Way ?</h3>
There are many stars, grains of dust, and gas in the Milky Way. It is known as a spiral galaxy because, from the top or bottom, it would appear to be whirling like a pinwheel. About 25,000 light-years from the galaxy's nucleus, the Sun is situated on one of the spiral arms.
The Milky Way galaxy is made up of billions of stars, as well as gas and dust, which are all drawn to one another by gravitational pull, as well as a significant amount of dark matter. Our galaxy is approximately 100,000 light years [e1] across.

Answer:
a)5.88J
b)-5.88J
c)0.78m
d)0.24m
Explanation:
a) W by the block on spring is given by
W=  kx² =
kx² =  (530)(0.149)² =  5.88 J
(530)(0.149)² =  5.88 J
b)  Workdone by the spring = - Workdone by the block = -5.88J
c) Taking x = 0 at the contact point we have U top = U bottom
So, mg =
 =  kx² - mgx
kx² - mgx
And,  = (
= (  kx² - mgx
)/(mg) =
kx² - mgx
)/(mg) =  ]/(0.645x9.8)
]/(0.645x9.8)     
     =   0.78m
=   0.78m            
d) Now, if the initial initial height of block is 3 
 
  = 3 x 0.78 = 2.34m
 = 3 x 0.78 = 2.34m
then,  kx² - mgx - mg
kx² - mgx - mg =0
 =0 
  
  (530)x²  - [(0.645)(9.8)x] - [(0.645)(9.8)(2.34) = 0
(530)x²  - [(0.645)(9.8)x] - [(0.645)(9.8)(2.34) = 0
265x² - 6.321x - 14.8 = 0  
a=265
b=-6.321
c=-14.8
By using quadratic eq. formula, we'll have the roots
x= 0.24 or x=-0.225
Considering only positive root:
x= 0.24m (maximum  compression of the spring)
