so
---> is negative because the airplane is descending
Answer:
n=3, l=1, ml=1ms=+1/2
Step-by-step explanation:
The electron configuration of chlorine atom is; [Ne] 3s² 3p⁵.
This means that the last electron is found in a 3pz orbital.
We can see that the principal quantum number is 3. The electron is in a p orbital so l=1, the electron must be found in a 3pz orbital hence ml=1. The electron is found alone in that orbital hence s= 1/2.
Answer:
DEH & DEJ
Step-by-step explanation:
It a acute and angle so it equal complementary
What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
