Answer:
6 seconds
Step-by-step explanation:
The computation of the number of second would be
In the case when the ball would hit the ground, the ball height would be zero
So the following equation would be

So the number of seconds is 6
Step-by-step explanation:
Y-0 = 1/4(x-8)
4Y= x-8
4Y-x+8=0
5s subshell represent that n is equal to 5 and l is equal to 0.
2p subshell represent that n is equal to 2 and l is equal to 1.
3d subshell represent that n is equal to 3 and l is equal to 2.
The numbers gives us the value of n and the letter gives us the value of l.
s means l = 0
p means l = 1
d means l = 2
f means l = 3
