Aluminum Chloride is written as -> A1C1 or A1C13

B would be Beryllium Sulfide (not monosulfide)

D is not a compound. There is other Selenium or Iodides

Your answer that is correct will be C - > calcium chloride

Convert 11 ppm into a percent

Tanya [424]

To convert ppm to percent, you divide the ppm by 10,000.

x / 10000 = x%

So, 11 ppm is 11/10000 or 0.0011%.

Answer:

Therefore, the revolutions that each tire makes is:

$\Delta \theta=22\: rev$

Explanation:

We can use the following equation:

$\omega_{f}^{2}=\omega_{i}^{2}-2\alpha \Delta \theta$ (1)

The angular acceleration is:

$a_{tan}=\alpha R$

$\alpha=\frac{1.9}{0.325}$

$\alpha=5.85\: rad/s^{2}$

and the initial angular velocity is:

$\omega_{i}=\frac{v}{R}$

$\omega_{i}=\frac{27.2}{0.325}$

$\omega_{i}=83.69\: rad/s$

Now, using equation (1) we can find the revolutions of the tire.

$0=83.69^{2}-2*25.85 \Delta \theta$

$\Delta \theta=135.47\: rad$

Therefore, the revolutions that each tire makes is:

$\Delta \theta=22\: rev$

I hope it helps you!
