Sure I can be your friend do you play video games
        
                    
             
        
        
        
The frequency of the wheel is given by:

where N is the number of revolutions and t is the time taken. By using N=100 and t=10 s, we find the frequency of the wheel:

And now we can find the angular speed of the wheel, which is related to the frequency by:
 
 
        
        
        
Force of gravity. Hope this is correct good luck!!
        
                    
             
        
        
        
Answer:

Explanation:
 = Permittivity of free space =
 = Permittivity of free space = 
A = Area = 
d = Thickness = 
k = Dielectric constant = 5.4
V = Voltage = 86.2 mV
Charge is given by
