Answer:
11.56521 m/s
Explanation:
 = Area of first section =
 = Area of first section = 
 = Area of second section =
 = Area of second section = 
 = Velocity in first section = 1.9 m/s
 = Velocity in first section = 1.9 m/s
 = Velocity in second section
 = Velocity in second section
From the continuity equation we get

The speed of the river through the section of rapids is 11.56521 m/s
 
        
             
        
        
        
Answer:
The probability for the proportion of apples with diameters less than 3.5 inches is 0.1056.
Explanation:
For a normal distribution, z score is calculated using this formula:  (X-μ)/σx
Where Mean, μ = 4
Standard deviation, σ = 0.400
The probability for the proportion of apples with diameters less than 3.5 inches is expressed below:
Probability =	P(X<3.5)	
                   =	P(Z<-1.25)	
Probability  = 0.1056
 
        
                    
             
        
        
        
Answer:
0.2631 N/C
Explanation:
Given that:
The radius of the wire r = 0.22 mm = 0.22 × 10⁻³ m
The radius of the thick wire  r' = 0.55 mm = 0.55 × 10⁻³ m
The numbers of electrons passing through B, N = 6.0  × 10¹⁸ electrons
Electron mobility  μ =  6.0 x 10-4 (m/s)/(N/C)
= 0.0006 
The number of electron flow per second is calculated as follows:




The magnitude of the electric field is:
E = 
E = 
E = 
E = 0.2631 N/C
