Good morning.
We have:

Where 
j is the unitary vector in the direction of the 
y-axis.
We have that 

We add the vector 
-a to both sides:

Therefore, the magnitude of 
b is 
47 units.
 
        
        
        
The answer in Meters is going to to 1265.341
        
                    
             
        
        
        
Answer:
1 m/s
Explanation:
Impulse = Change in momentum
Force × Time = Mass(Final velocity) - Mass(Initial Velocity)
(1.0)(1.0) = (1.0)(Final Velocity) - (1.0)(0)
Final velocity = <u>1 m/s</u>
 
        
             
        
        
        
Answer:
b)  the result we got can be termed approximation because we are neglecting the shear stress acting on the two ends of the cylinder. Here we have considered only the share stress acting on the curved surface area only.

Answer:
4 ohms
Explanation:
Current = Voltage/resistance
2 = 8/R
2R = 8
R = 4
