Answer:
C) 350 m/s N
Explanation:
Velocity is measured in miles per hour or metres per second.
Answer: Homogenous mixture.
Explanation:
Explanation:
Given that,
Initial speed of a car, u = 12 m/s
Aceleration, a = -1.6 m/s²
(a) The displacement of car after 6 seconds is :

(b) The displacement of the car after 9 seconds is :

Hence, this is the required solution.
<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
