<h3><u>Answer;</u></h3>
= 0.0000001 mol/L
= 0.0000001 mol/L
= 1:1
<h3><u>Explanation;</u></h3>
What is the concentration of H+ ions at a pH = 7?
The formula for ph is given by:
pH=−log10[H+]
In calculating for the concentration of hydrogen ion, the formula is given by:
[H+]=(10)^(-pH)
Therefore; at pH = 7
[H+]=(10)^(-7)
<u>= 0.0000001 mol/L </u>
What is the concentration of OH– ions at a pH = 7?
pH+pOH=14
7+pOH=14
pOH= 7
[OH-]=(10)^(-pOH)
[OH-]=(10)^(-7)
<u>= 0.0000001 mol/L </u>
What is the ratio of H+ ions to OH– ions at a pH = 7?
1:1
The circulation around the cylinder is 0.163Js/kg.
To find the answer, we have to know more about the stream flow.
<h3>
How to find the circulation around the cylinder?</h3>
, where d is the density at the sea level.
- We have the expression for lift per unit circulation as,
- Thus, the circulation around the cylinder is,
Thus, we can conclude that, the circulation around the cylinder is 0.163Js/kg.

Answer:
294.4 N
Explanation:
Since the hose obeys Hooke's law, the force it exerts on the balloon in the pouch is given by:
where
k is the spring constant
x is the stretching
In this problem,
k = 92.0 N/m
x = 3.20 m
Therefore, the force exerted is
Answer:
Explanation:
Given that,
The diameter of a human blood cell is 0.0000062 m. We need to express in scientific notation.
Any no can be written in scientific notation as follows :
n and m are real no and integer respectively
0.0000062 has 5 zeroes before 6. It means its scientific notation is as follows :
