With angular momentum quantum number l = 2. in units of ħ, the value of l will be 2.4494 h.
<h3>What is the angular momentum quantum number?</h3>
The total angular momentum quantum number in quantum mechanics parametrizes the total angular momentum of a particular particle by combining its orbital angular momentum and intrinsic angular momentum.
Given the angular momentum quantum number l = 2. in units of ħ. Therefore, the value of L can be written as,
L = √[l (l + 1)]
L = √[2 (2 + 1)]
L = √[2 (3)]
L = √6
L = 2.4494 h
Hence, With angular momentum quantum number l = 2. in units of ħ, the value of l will be 2.4494 h.

Answer:
G. 2s
Explanation:
The period of a pendulum is measured in time. Out of the four options, only one of them is measured in time so it must be G.
A period of a pendulum is how long it takes to swing back to it's original position, and this time (2 seconds) is given in the question as well
Answer:
30.36°
Explanation:
By using linear momentum; linear momentum can be expressed by the relation:
where ;
m= mass
= velocity of components in the x direction
= velocity of components in the y direction
If we consider the east as the positive x and north as positive y which is synonymous to what we usually have on a graph.
Then;
Initial momentum = 
= 
However, the masses stick together after collision and move with a common velocity: 
∴ Final momentum = 
= 
From the foregoing ;
initial momentum = final momentum
So;
Finally;
The required angle θ = 
θ = 
θ = 
θ = 30.36°
Constant acceleration is when the velocity changes the same amount in every equal time period. For example : 9.8 m/s^2
Instantaneous acceleration is the rate at which velocity changes at a specific instant in time. For example: at one point it might be 8m/s^2 and at another point 13m/s^2
