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:
distance = 27.95 [mi]
Explanation:
in order to solve this problem, we must use the appropriate conversion factor, i.e. a conversion factor that relates the kilometers to Miles.
![1 [km] = 0.6214 [mill]\\45[km]*0.6212[\frac{mill}{1km} ]=27.95 [mill]](https://tex.z-dn.net/?f=1%20%5Bkm%5D%20%3D%200.6214%20%5Bmill%5D%5C%5C45%5Bkm%5D%2A0.6212%5B%5Cfrac%7Bmill%7D%7B1km%7D%20%5D%3D27.95%20%5Bmill%5D)
If an object is at rest, then its distance doesn't change as time goes on.
On the graph, the points for each time are all at the same distance. They form a horizontal line.
Well it breaks it away from rain or earthqukes depends but then depostion takes the rocks away and a delta takes it into the ocean
Answer:
B) The car at point C has less kinetic energy than the car at point B.
Explanation:
We have two types of energy involved in this situation:
- Gravitational potential energy: this is the energy related to the heigth of the car, and it is given by 
, where m is the mass of the car, g is the gravitational acceleration, and h is the heigth of the car. The potential energy is higher when the car is located higher above the ground.
- Kinetic energy: this is the energy due to the motion of the car, and it is given by 
, where m is the mass of the car and v is its speed. The kinetic energy is higher when the speed of the car is higher.
- The law of conservation of energy states that the total mechanical energy of the car (sum of potential energy and kinetic energy: 
) is constant). This implies that when the car is at a higher point, the kinetic energy is less (because U is larger, so K must be smaller), while when the car is at a lower point, the kinetic energy is larger.
- Based on what we have written so far, we can conclude that the correct statement is:
B) The car at point C has less kinetic energy than the car at point B.
Because the car at point C is located at a higher point than point B, so the car at point C has larger potential energy than at point B, which implies that car at point C has less kinetic energy than the car at point B.
