Given that

Cylinder density = 3.75 g/ cm^3

Mass of cylinder = 12.1 g

Diameter = 8.22 cm

Radius, r = diameter /2 = 8.22 /2 cm = 4.11 cm

Now calculate the volume as follows:

Volume = mass / density

= 12.1 g/ 3.75 g/ cm^3

= 3.23 cm^3

Now with the use of volume of cylinder calculate the height as follows:

Volume of cylinder = πr^2h

3.23 cm^3 = 3.14 * (4.11 cm)^2 *h

h = 3.23 cm^3 / 3.14 * (4.11 cm)^2

=0.061 cm

According to Newton's third law, forces come in pairs. There is_____and an equal and opposite_____.

hichkok12 [17]

According to Newton's third law, forces come in pairs. There is action-reaction force and an equal (in size - action force) and opposite in direction (reaction force).

<u>Explanation:</u>

On the off chance, when item A applies a force on item B, at that point item B must apply a force of equivalent size and inverse bearing back on object A. This Newton's third law speaks to a specific balance in nature: forces consistently happen two by two.

And, one body can't apply a force on another without encountering a force itself. Now and again, allude to this law freely as activity response, where the force applied is the activity and the force experienced as a result is the response.

Which element is used for the shiny trim on cars

galben [10]

<span>The correct answer is either Chrome (Chromium), or Aluminum. Unlike steel, these two don't rust easily and can be polished to be quite shiny, especially Chromium, which is why you'll always hear people who like cars talking about chrome wheels and chrome spoilers and things like that. They are not that good for bumpy or roads that are full of holes because they can bend much easier than steel so it can be expensive to maintain.</span>

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pr

Delvig [45]

<h2>Hello!</h2>

The answer is: Charle's Law.

The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.

The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:

$\frac{V}{T}=k$

Where,

$V=Volume\\T=Temperature\\k=constant$

Also, to describe the relationship between two differents volumes at different temperatures, we have:

$\frac{V_{i}}{T_{i}}=\frac{V_{f}}{T_{f}}$

Where,

$V_{i}=InitialVolume\\T_{i}=InitialTemperature\\V_{f}=FinalVolume\\T_{f}=FinalTemperature$

Have a nice day!
