Answer:B
Explanation:
Given
Distance of astronaut From asteroid x is 
Distance of astronaut From asteroid Y is 
Suppose M,M_x,M_y be the masses of Astronaut , asteroid X and Y
If the astronaut is in equilibrium then net gravitational force on it is zero


cancel out the common terms we get




 
        
             
        
        
        
Explanation :
Bioinformatics is the science that manages the database, digital tools and software used by both medicine and forensic science to store and analyze DNA.
It involves the use of computers to collect all the data and organize data. It also develops methods and computational tools for understanding biological data. 
It helps in tracing the evolution of organism using DNA and builds a computational model.
 
        
             
        
        
        
A skill set is explicitly taught or an activity is completed
        
             
        
        
        
N2(g)<span> + 3H</span>2(g)<span> → 2NH</span><span>3(g) Is the answer. </span>
        
                    
             
        
        
        
When It begins to drop because that when gravity will have its strongest pull on the object.
