Detergents are special, powerful cleansers that can break up dirt, oils, and grease in clothing or on dishes.
Cleaning solvents are used to remove oil, grease, solder flux, and other contaminants.
Acid cleaners are generally used to remove mineral deposits and are useful for descaling dishwashers or removing rust from restroom facilities.
Abrasive uses
* Buffing.

* Sanding.
* Polishing.
* Cutting.
* Sharpening.
It'd be an unbalanced force
Well, the acceleration is the difference of speeds divided by the time period.
![\frac{32.4}{0.5}=64.8rev/s^2](https://tex.z-dn.net/?f=%5Cfrac%7B32.4%7D%7B0.5%7D%3D64.8rev%2Fs%5E2)
.
One rev/s is
![2\pi rad/s^2](https://tex.z-dn.net/?f=2%5Cpi%20rad%2Fs%5E2)
, so our final result is
![64.8*2\pi=407.15rad/s^2](https://tex.z-dn.net/?f=64.8%2A2%5Cpi%3D407.15rad%2Fs%5E2)
.
If one of two interacting charges is doubled, the force between the charges will double.
Explanation:
The force between two charges is given by Coulomb's law
![F=\frac{k q1 q2}{r^{2}}](https://tex.z-dn.net/?f=%20F%3D%5Cfrac%7Bk%20q1%20q2%7D%7Br%5E%7B2%7D%7D%20%20%20)
K=constant= 9 x 10⁹ N m²/C²
q1= charge on first particle
q2= charge on second particle
r= distance between the two charges
Now if the first charge is doubled,
we get ![F'=\frac{k (2q1) q2}{r^{2}}](https://tex.z-dn.net/?f=%20%20F%27%3D%5Cfrac%7Bk%20%282q1%29%20q2%7D%7Br%5E%7B2%7D%7D%20%20%20%20)
F'= 2 F
Thus the force gets doubled.
