Answer:
3 820 885 N
Explanation:
Gravitational equation 
    F = G  m1 m2 / r^2     
          G = gravitational constant = 6.6713 x 10^-11 m^3/kg-s^2
F = 6.6713 x 10^-11   *   4.41 x 10^5  * 5.97 x 10^24  / ( 6.78x 10^6)^2 
  = 3820885 .3 N
 
        
             
        
        
        
Answer:
Transferred material is in the same relative position on the disk as on the original sample
Explanation:
The usefulness of blotting techniques in molecular biology is that transferred material is in the same relative position on the disk as on the original sample
 
        
             
        
        
        
At the present time, the only way we know of that light can get shifted 
toward the blue end of the spectrum is the Doppler effect ... wavelengths 
appear shorter than they should be when the source is moving toward us.  
IF that's true in the case of the Andromeda galaxy, it means the galaxy is 
moving toward us.
We use the same reasoning to conclude that all the galaxies whose light is red-shifted are moving away from us.  That includes the vast majority of all galaxies that we can see, and it strongly supports the theory of the big bang 
and the expanding universe.
If somebody ever comes along and discovers a DIFFERENT way that light 
can get shifted to new, longer or shorter wavelengths, then pretty much all 
of modern Cosmology will be out the window.  There's a lot riding on the 
Doppler effect !
