I want to say addition. But I have a tendency to be wrong
Answer:
ARE U STILL GIVING BRAINLIEST?
Explanation:
First, we will get the average pH of the two given values:
average pH = (6.4+8) / (2) = 7.2
At this average pH, the concentration of the acid from the phenol red is equal to the concentration of the base.
pH = 7.2
[H+] = 10^(-7.2) = 6.3 * 10^-8
Phenol red has the general formula HA, this gives us:
HA <.......> H+ + A-
At pH = 7.2, [H+] = [A-]
<span>Ka = [H+][A-]/ [HA]
</span>Ka = [H+] = <span>6.3 x 10^-8</span>
From the information given, the mass of the hammer seems to be 1.36 kg and the velocity by which it is wielded seems to be 22 m/s.
The most suitable formula to be used here is :
f = m × v
where f is force, m is mass and v is velocity.
f = m × v → f = 1.36 × 22 → f = 29.92 kg m/s
Therefore the force generated by the hammer is 29.92 N
( kg m/s is the same as Newton)
