1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.

1 gram = 1000 mg

10 grams x 1000 mg = 10,000 mg

Divide total mg by mg per can:

10,000 / 24.12 = 414.59 cans

Round to 415 cans

The list of options to answer this question is:

A.kinectic energy is transformed into thermal energy.

B.electrical energy is transformed into potential energy.

C.potential energy is transformed into kinectic energy.

D.mechanical energy is transformed into chemical energy.

The answer is the option A. A.kinectic energy is transformed into thermal energy.

As you know energy cannot be lost but transformed.

When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.

Air has a mass of 1.2g and a volume of 4,555ml. What is the density
coldgirl [10]

Answer:

<h2>Density = 0.00026 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>Density(\rho) =  \frac{mass}{volume}</h3>

From the question

mass of air = 1.2 g

volume = 4,555 mL

Substitute the values into the above formula and solve for the density

That's

<h3>Density =  \frac{1.2}{4555}</h3>

= 0.0002634

We have the final answer as

<h3>Density = 0.00026 g/mL</h3>

Hope this helps you
