The answer is A
Hope that helps!
Answer:
True
Explanation:
Bohr proposed an atomic model in which;
- the electrons found in an atom can only occupy orbits for which the angular momentum is quantized, which results in discrete values of energy level.
- the electrons in such stationary state or ground state emits no light, but
- if an electron jumps to a lower state, it emits a photon whose energy equals the difference in energy between the two states.
Answer:
The voltage is ![V_c = 9.92 \ V](https://tex.z-dn.net/?f=V_c%20%20%3D%209.92%20%5C%20V)
Explanation:
From the question we are told that
The voltage of the battery is ![V_b = 24 \ V](https://tex.z-dn.net/?f=V_b%20%20%3D%20%2024%20%5C%20V)
The capacitance of the capacitor is ![C = 3.0 mF = 3.0 *10^{-3} \ F](https://tex.z-dn.net/?f=C%20%20%3D%20%203.0%20mF%20%20%3D%20%203.0%20%2A10%5E%7B-3%7D%20%5C%20%20F)
The resistance of the resistor is ![R = 100\ \Omega](https://tex.z-dn.net/?f=R%20%20%20%3D%20%20100%5C%20%20%5COmega)
The time taken is
Generally the voltage of a charging charging capacitor after time t is mathematically represented as
![V_c = V_o (1 - e^{- \frac{t}{RC} })](https://tex.z-dn.net/?f=V_c%20%20%3D%20%20V_o%20%281%20-%20%20e%5E%7B-%20%5Cfrac%7Bt%7D%7BRC%7D%20%7D%29)
Here
is the voltage of the capacitor when it is fully charged which in the case of this question is equivalent to the voltage of the battery so
![V_c = 24 (1 - e^{- \frac{0.16}{100 * 3.0 *10^{-1}} })](https://tex.z-dn.net/?f=V_c%20%20%3D%20%2024%20%281%20-%20%20e%5E%7B-%20%5Cfrac%7B0.16%7D%7B100%20%2A%203.0%20%2A10%5E%7B-1%7D%7D%20%7D%29)
![V_c = 9.92 \ V](https://tex.z-dn.net/?f=V_c%20%20%3D%209.92%20%5C%20V)
