To develop this problem it will be necessary to apply the concepts related to the frequency of a spring mass system, for which it is necessary that its mathematical function is described as

Here,
k = Spring constant
m = Mass 
Our values are given as,


Rearranging to find the spring constant we have that,




Therefore the spring constant is 1.38N/m
 
        
             
        
        
        
Well, I think mostly it is oceanic crust well because <span>The scientist noticed a symmetrical pattern of positive and negative magnetic lines as they moved along the ocean floor, and the line of symmetry was at the mid-ocean ridge. that why it is seen as the youngest on our earth</span>
        
                    
             
        
        
        
Helium has only 2 electrons in it's valence shell
So, option D is your answer.
Hope this helps!
        
             
        
        
        
Answer:
Explanation:
Flux Φ = nBA sinωt
t = 0 , flux = 0 
dΦ / dt = nωBA Cosωt
e = nωBA Cosωt
= 100 x 2πx80 x.3 x .003 cos 2πx80 x .014
= 45.21 cos 7.0336
= 33.0668 v 
= 33.1 V
