Answer:
The answer is
<h2>5.50</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
![volume = \frac{mass}{density} \\](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20%20%5C%5C%20)
From the question
mass = 22 g
density = 4 g/mL
The volume is
![volume = \frac{22}{4} = \frac{11}{2} \\](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B22%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B11%7D%7B2%7D%20%20%5C%5C%20)
We have the final answer as
<h3>5.50 mL</h3>

Answer:
When the red test lead is positive (+) and the black test lead negative (-), the meter will register voltage in the normal direction.
Explanation
Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect radio waves directed into the sky back toward the Earth. Radio waves directed at an angle into the sky can return to Earth beyond the horizon.
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}](https://tex.z-dn.net/?f=Density%28%5Crho%29%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20)
</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}](https://tex.z-dn.net/?f=Density%20%3D%20%20%5Cfrac%7B1.2%7D%7B4555%7D%20)
</h3>
= 0.0002634
We have the final answer as
<h3>Density = 0.00026 g/mL</h3>

Answer:
Go to the bottom-right corner of your taskbar, then click the Volume Control icon. A small window will pop up, and it will offer access to the volume level control. Slide the bar to set the volume to your preferred level. This may be one of the quickest and easiest ways to change the volume level of your computer.
