<h3><u>Answer;</u></h3>
pH = 6.34
<h3><u>Explanation;</u></h3>
pH is given as -log{H+]
But;
pH + pOH = 14
However;
pOH = -log [OH-]
[OH-] = 2.20 × 10−8 M
Thus;
pOH = -log (2.20 × 10−8 M)
= 7.66
But;
pH = 14 - pOH
= 14 - 7.66
<u>= 6.34 </u>

The relation between force, mass of an object and its acceleration is given by following equation
F = mass of object X acceleration
The unit of Force is Newton (N)
unit of acceleration is ms⁻²
unit of mass if Kg
[all these are SI units]
Mass of object =
mass of sprinter =
