Answer:
Explanation:
Given that 
F=ax^3/2. a is a constant 
The force does a work of
W=2.01KJ from x=0 to x=15.2m
We need to find a
Work is give as,
W=∫F.ds
But this is in x direction only then,
W=∫Fdx. from x=0 to x=15.2m
W=∫ax^3/2dx from x=0 to x=15.2m
W=ax^(3/2+1)/(3/2+1). 
W=ax^(5/2)/5/2
W=ax^(2/5)/2.5 from x=0 to x=15.2m
Cross multiply
2.5W=ax^2.5. from x=0 to x=15.2m
2.5W= a (15.2^2.5-0)
W=2.01KJ=2010J
2.5×2010=a×900.76
Therefore,
a=5.56
 
        
             
        
        
        
When a valence electron absorbs energy in the form of heat or light it uses that energy to jump to an excited state (outer level)
        
             
        
        
        
Helium and nitrogen because they are both from the noble gas group.
