Answer:
290 N
Explanation:
Total downward force = Force applied on the door in bringing it down + weight of the door
Total downward force = 80 + 210
Total downward force = 290N
You are given both the energy level, n = 4, and the subshell, l = 3 on which the electrons reside.
The subshell is given to you by the angular momentum quantum number, l which can take value that ranges from 0 to n − 1
l = 0 → the s-subshell
l = 1 → the p-subshell
l = 2 → the d-subshell
l = 3 → the f-subshell
<u>For n = 4 and l = 3, ml can be -3, -2, -1, 0, +2, +2, and +3. </u>
<u>Each of these can have 2 electrons (+1/2 and -1/2 spin) for a total of 14 electrons.</u>
