Answer:
a) 1.875 volts
b) 5.86 W
Explanation:
Given data:
transmission line resistance = 0.30/cable
power of the generator = 250 kW
if Vt = 80 kV
<u>a) Determine the decrease V along the transmission line </u>
Rms current in cable = P / Vt = 250 / 80 = 3.125 amps
hence the rms voltage drop ( Δrmsvoltage )
Δrmsvoltage = Irms* R = 3.125 * 2 * 0.30 =<em> 1.875 volts </em>
<u>b) Determine the rate Pd at which energy is dissipated in line as thermal energy </u>
Pd = 
= 3.125^2 * 2* 0.30 = <em>5.86 W</em>
Answer:
The answer is "Keep at least a couple of extra digits beyond those needed for determining significant figures."
Explanation:
From equations of motion,
v^2 = u^2 + 2as ----- v = final velocity, u = initial velocity, a = acceleration, s = distance covered.
Using the vales given;
v^2 = 15^2 + 2*4*50 = 625
v = Sqrt (625) = 25 m/s
