The height of the ceiling in the school gym from the floor is 11.48m.
HOW TO CALCULATE HEIGHT OF A PROJECTILE:
- Using one of the equations of motion as follows:
v² = u² + 2as
Where;
v = final velocity (m/s)
u = initial velocity (m/s)
a = gravitational acceleration (m/s²)
s = distance traveled (m)
According to this question,
- The final velocity (v) of the volleyball is 15m/s
- The initial velocity is 0m/s
- The acceleration due to gravity is 9.8m/s
Using the formula, v² = u² + 2as, the height of the ceiling (s) can be calculated as follows:
15² = 0² + 2 (9.8) (s)
225 = 0 + 19.6s
225 = 19.6s
s = 225/19.6
s = 11.48m
Therefore, the height of the ceiling in the school gym from the floor is 11.48m

With regard to Neural Permeability, the relationships between the two items listed in each care is as follows:
- A. Resting neuron's permeability to K⁺
- B. Resting neuron's permeability to Na⁺ (Option C)
- A. Neuron's permeability to Na⁺ during the rising phase of an action potential
- B. Neuron's permeability to K⁺ during the rising phase of an action potential (Option F)
- A. Resting neuron's permeability to Na⁺
- B. Neuron's permeability to Na⁺ during the rising phase of an action potential (Option B)
- A. Resting neuron's permeability to K⁺
- B. Neuron's permeability to K⁺ during the falling phase of an action potential (Option A)
- A. Neuron's permeability to Na⁺ during the falling phase of an action potential
- B. Neuron's permeability to K⁺ during the falling phase of an action potential (Option D)
It is to be noted that the grading is as follows:
A) is for when B is greater than A
B) is for when B is greater than A
C) is for when A is greater than B
D) is for when B is greater than A
E) is for when A and B are equal
F) A is greater than B
<h3>What is Neural permeability?</h3>
This (in simple terms) refers to the degree to with neurons allow the transmission of solutes and solvents in and out of them.
