The angular quantum number

can be any integer (whole number) between 0 and one less than the principal quantum number

.

cannot be -3, -2, or -1. The other solutions depending on what the principal quantum number is.
Answer:
This formula:
Cylinder Volume = π • r² • height
Volume = PI * 4 ^2 * 5
Volume = PI * 16 * 5
Volume = 251.327412 cubic inches
Step-by-step explanation:
Answer:
9 seconds
Step-by-step explanation:
d=-16t²+vt+h
The water level will be at 0 level (distance = 0)
0 = 16t² - 90t - 486
8t² - 45t - 243 = 0
(t - 9) (8t + 27) = 0
t = 9 or t = -27
since time should be a positive number, so t = 9 second
