The orbital angular momentum is given by: \[ L = \frac{\sqrt{l(l+1)}h}{2\pi}. \] For an \(s\)-orbital, \(l = 0\). Substituting \(l = 0\): \[ L = \frac{\sqrt{0(0+1)}h}{2\pi} = 0. \]
Final Answer: \( \boxed{0} \).
Regarding the molecular orbital (MO) energy levels for homonuclear diatomic molecules, the INCORRECT statement(s) is (are):
Which one of the following graphs accurately represents the plot of partial pressure of CS₂ vs its mole fraction in a mixture of acetone and CS₂ at constant temperature?

In the given figure, the blocks $A$, $B$ and $C$ weigh $4\,\text{kg}$, $6\,\text{kg}$ and $8\,\text{kg}$ respectively. The coefficient of sliding friction between any two surfaces is $0.5$. The force $\vec{F}$ required to slide the block $C$ with constant speed is ___ N.
