The axle and Wheel are 2 circles, and they rotate together. Force is usually transferred from the axle to the wheel. The mechanical advantage of the wheel and axle is essentially the ratio of the radius of the wheel over the radius of the axle
MA =Radius of wheel
Radius of Axle
Explanation:
The pH of the solution is 9.63 ± 0.03.
we know that
pH= -log[H+]
⇒[H+] =
= =
Now to find absolute error we use the formula
Absolute error/[H+] =ln10(uncertainity)
Absolute error = ln10×[H+] ×0.03
=
Answer:
Explanation:
