If the quantum number (n, l, ml) for an electron are (5, 3, 0) what orbital is the electron in
spayn [35]

Answer:

orbital 3 also called orbital f

Explanation:

In the resolution of the Schrödinger equation for the three-dimensional hydrogen atom with spherical coordinates three constants appear, which are related, these constants are called quantum numbers.

The first one is the number n called the main quantum number and its value ranges from to infinity

The second number is called the orbital quantum number (l) and has values ​​from zero to n-1

The third number corresponds to the magnetic orbital quantum number and thymus values ​​from –l to l

Let us apply to our case, state (5, 3, 0) corresponds to a state in period 5 of

the quantum number, with orbital 3 also called orbital f and with magnetic number 0 that e spherical

The electric potential difference of a 150 µF capacitor is measured across the terminals of the capacitor and found to be 5 volt
Lapatulllka [165]
The potential energy stored in a capacitor is given by:
U= \frac{1}{2}CV^2
where
C is the capacitance of the capacitor
V is the potential difference across the plates of the capacitor

In our problem,
C=150 \mu F= 150 \cdot 10^{-6} F
V=5 V
Therefore, the potential energy of the capacitor is
U= \frac{1}{2}(150 \cdot 10^{-6}F)(5 V)^2 = 1.88 \cdot 10^{-3}J
