Answer:
Answer is c Heisenberg's uncertainty principle
Explanation:
According to Heisenberg's uncertainty principle there is always an inherent uncertainty in measuring the position and momentum of a particle simultaneously.
Mathematically
![\Delta x\times \Delta \overrightarrow{p}\geq \frac{h}{4\pi }](https://tex.z-dn.net/?f=%5CDelta%20x%5Ctimes%20%5CDelta%20%5Coverrightarrow%7Bp%7D%5Cgeq%20%5Cfrac%7Bh%7D%7B4%5Cpi%20%7D)
here 'h' is planck's constant
Answer:
(a) Calculate the rod base temperature (°C). = 299.86°C
(b) Determine the rod length (mm) for the case where the ratio of the heat transfer from a finite length fin to the heat transfer from a very long fin under the same conditions is 99 percent. = 0.4325m

Answer:
the generator induced voltage is 60.59 kV
Explanation:
Given:
S = 150 MVA
Vline = 24 kV = 24000 V
![X_{s} =1.23(\frac{V_{line}^{2} }{s} )=1.23\frac{24000^{2} }{1500} =4723.2 ohms](https://tex.z-dn.net/?f=X_%7Bs%7D%20%3D1.23%28%5Cfrac%7BV_%7Bline%7D%5E%7B2%7D%20%20%7D%7Bs%7D%20%29%3D1.23%5Cfrac%7B24000%5E%7B2%7D%20%7D%7B1500%7D%20%3D4723.2%20ohms)
the network voltage phase is
![V_{phase} =\frac{V_{nline} }{\sqrt{3} } =\frac{27}{\sqrt{3} } =15.58kV](https://tex.z-dn.net/?f=V_%7Bphase%7D%20%3D%5Cfrac%7BV_%7Bnline%7D%20%7D%7B%5Csqrt%7B3%7D%20%7D%20%3D%5Cfrac%7B27%7D%7B%5Csqrt%7B3%7D%20%7D%20%3D15.58kV)
the power transmitted is equal to:
![|E|=\frac{P*X_{s} }{3*|V_{phase}|sinO } ;if-O=60\\|E|=\frac{300*4.723}{3*15.58*sin60} =34.98kV](https://tex.z-dn.net/?f=%7CE%7C%3D%5Cfrac%7BP%2AX_%7Bs%7D%20%7D%7B3%2A%7CV_%7Bphase%7D%7CsinO%20%7D%20%3Bif-O%3D60%5C%5C%7CE%7C%3D%5Cfrac%7B300%2A4.723%7D%7B3%2A15.58%2Asin60%7D%20%3D34.98kV)
the line induced voltage is
![|E_{line} |=\sqrt{3} *|E|=\sqrt{3} *34.98=60.59kV](https://tex.z-dn.net/?f=%7CE_%7Bline%7D%20%7C%3D%5Csqrt%7B3%7D%20%2A%7CE%7C%3D%5Csqrt%7B3%7D%20%2A34.98%3D60.59kV)
