Explanation:
(a)   Formula to calculate the density is as follows.
             
                        = 
                      = 
Now, calculate the charge as follows.
             
                       = 
                       =  C
 C
or,                   = 101.06 nC
(b)  For r = 6.50 cm, the value of charge will be calculated as follows.
                 
                           = 
                           = 7.454 
 
        
             
        
        
        
Answer:
c
Explanation:
i would think c would be correct because 
blood temperature IS affected by muscles
digestion IS affected by muscles 
speech IS affected by muscles
so therefore <em>hair growth</em> IS NOT affected by muscles

The frequency, f, of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz (Hz), since one hertz is equal to one wave per second.
