That's some crazy equations...is there more to the question?
One of the most popular best sensitive teeth whitening toothpaste are those that contain active whitening ingredients such as carbamide peroxide.
<h3>How does a teeth whitening toothpaste work?</h3>
A teeth whitening toothpaste works by removing plaque from the teeth gently and ensures the the teeth is protected from germs that can cause aches and decay.
This is a contrast to traditional toothpastes that only clean for fresh breath.
<h3>What are the constituents of a teeth whitening toothpaste?</h3>
Basically, extrinsic stains are removed by traditional whitening toothpaste's abrasives and bleaching ingredients, such as:
- Silica
- Pyrophosphates
- Hydrogen peroxide, or carbamide peroxide, which also brighten the color of the teeth.
<h3>How does teeth whitening paste or gels work?
</h3>
All whitening gels contain carbamide peroxide, which breaks down into hydrogen peroxide once applied to the teeth.
The stains and any severe discoloration on your teeth interact chemically with hydrogen peroxide.
Thus, it is important to note that any toothpaste that contains the above ingredients will most likely be able to carry out teeth whitening.

The tension in the string an instant before it broke is; T = 0.86 N
<h3>What is the Tension in the string?</h3>
We are given;
mass of ball; m = 60 g = 0.06 kg
Length of string; L = 70 cm = 0.7 m
Height the ball reaches; h = 150 cm = 1.5 m
From Newton's equation of motion;
v² - u² = 2as
where v = 0 m/s Thus;
-u² = 2(-9.81 * (1.5 - 0.7)
u² = 15.696
u = √15.696
u = 3.17 m/s
Thus, tension is;
T = mu²/L
T = (0.06 * 3.17²)/0.7
T = 0.86 N
