The 2nd Law says F=ma, where F is the force in Newtons, m is mass and a is acceleration.  Earth's gravity is an acceleration, 9.8m/s^2.  So you can solve the equation for mass, m=F/a, or m=F/9.8 where you've measured the force (weight) in Newtons.
        
                    
             
        
        
        
Answer:
<u>The asteroid was not detected until it was extremely close to Earth. </u>
Explanation:
According to data from NASA, the Asteroid named 'Astriod 2019 OK', was detected when it was extremely close to earth with just about an estimated distance of  73,000 kilometers  (45,000 miles) from the Earth.
Scientists were concerned at the proximity of this space object to the Earth before it was discovered, and it brought about a cause of concern that since it was not extremely large (estimated 57 to 130 meters wide) it creates a potential for other smaller asteroids to escape detection and struck the earth.

Answer:
The approximate number of decays  this represent  is   
  
Explanation:
  From the question we are told that 
     The amount of Radiation received by an average american is 
      The source of the radiation is 
  Generally 
             
    Therefore  
Also  
   Therefore  
            An Average american weighs 88.7 kg
       The total energy received is mathematically evaluated as 
         
 Cross-multiplying and making x the subject 
            
               
Therefore the total  energy  deposited is 
 The approximate number of decays  this represent  is mathematically evaluated as 
             N = 
Where n is the approximate number of decay
    Substituting values 
                               
   
                                    
  
                       
              
 
        
             
        
        
        
I am made of literally THOUSANDS of compounds ... too many to list here.
But the one compound that's most abundant, and actually comprises almost
80% of my entire beautiful body, is the compound DiHydrogen Oxide, with 
the molecular formula H₂O .  This compound is commonly known as "water".
