Answer:
option B
Explanation:
Given,
Refractive index of the glass, n₂ = 1.50
Refractive index of plastic, n₁ = 1.30
critical angle = ?
![\theta_{critical}=\sin^{-1} (\dfrac{n_1}{n_2})](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D%5Csin%5E%7B-1%7D%20%28%5Cdfrac%7Bn_1%7D%7Bn_2%7D%29)
n₁ is the refractive index of the rare medium
n₂ is the refractive index of the denser medium.
![\theta_{critical}=\sin^{-1} (\dfrac{1.30}{1.50})](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D%5Csin%5E%7B-1%7D%20%28%5Cdfrac%7B1.30%7D%7B1.50%7D%29)
![\theta_{critical}=\sin^{-1} (0.8667)](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D%5Csin%5E%7B-1%7D%20%280.8667%29)
![\theta_{critical}=60.1^\circ](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D60.1%5E%5Ccirc)
The correct answer is option B
Answer:
b. The voltage across the resistor is equal to the terminal voltage of the battery, and the voltage across the capacitor is zero.
Explanation:
<em>When the system reaches its steady state the current tends to zero, then</em>
<em>in the resistor</em>
<em>V=IR</em>
<em>I=0, then </em><em>V=0</em>
<em>the capacitor charged is like an interruption in the circuit. </em><em>If we mesure voltage on both sides of the battery and if we mesure both sides of the capacitor, we will get the same value</em><em>, as its not any component between them in one side, and, in the other, the only component is the resistor that, without any courrent doesn't discipates any energy.</em>
Answer:
It becomes a giant or supergiant.
Explanation:
Once all the hydrogen supply is gone, fusion of hydrogen into helium stops. The core starts to contract and liberates energy, which heats the superior layer until it becomes hot enough to start the fusion of hydrogen into helium.
