The rms current in the transmission lines is I = 487.18 A.
The root-imply-rectangular (rms) voltage of a sinusoidal supply of electromotive force  is used to represent the source. it is the rectangular root of the time average of the voltage squared.
Alternating-present day circuits. the root-imply-square (rms) voltage of a sinusoidal source of electromotive force is used to symbolize the supply. it's far the square root of the time average of the voltage squared.
Electric power is  by using present day or the waft of electric fee and voltage or the capacity of rate to deliver electricity. A given cost of power can be produced by using any combination of contemporary and voltage values
power = 38 M watt
rms voltage = 78 K v
power = IV
I = power/V
I = (38 * 1000000)/78*1000
I = 487.18 A.

Answer:
  N = 23.4 N
Explanation:
After reading that long sentence, let's solve the question
The contact force is the so-called normal in this case we can find it by writing the translational equilibrium equation for the y axis
             N - w₁ -w₂ =
             N = m₁ g + m₂ g
             N = g (m₁ + m₂)
let's calculate
             N = 9.8 (0.760 + 1.630)
             N = 23.4 N
This is the force of the support of the two blocks on the surface.
 
        
             
        
        
        
No,because a Kevin is 7.242971666663E+22 times Smaller than a Joule.
        
                    
             
        
        
        
Since it was dropped, it should be the speed of gravity which is 9.8 meters/second
        
             
        
        
        
Fk = μK N
N = m a
N = 4 × a 
N = 4a
Fk = μK N
17 = 5 × 4a
17 = 20 a
a = ¹⁷/₂₀ = 0.85 m/s²
