The statement “The mechanical advantage of a compound
machine is equal to the one simple machine that has the greatest mechanical
advantage” is TRUE. I am hoping that this answer has satisfied your
query and it will be able to help you in your endeavor, and if you would like,
feel free to ask another question.
Wind<span> is the horizontal movement of air from an area of high pressure to an area of low pressure.</span>
<span>Winds are caused by differences in air pressure. </span>
These differences are caused by the uneven heating of the Earth’s surface.
<span>Winds are named by their direction (where they originate from) and speed.</span>
<span>Wind speed is measured by an anemometer.</span>
<span>v<span> </span></span>Local Winds:<span> winds that blow over short distances-caused by the uneven heating of Earth’s surface within a small area. They form only when large-scale winds are weak.</span>
<span>Ø<span> </span></span>Sea Breeze<span><span>: </span>a local wind that blows from an ocean or a lake.</span>
<span>§<span> </span></span> Occurs because land heats up faster than water – The warm air expands creating an area of low pressure over the land, so the cooler more dense air moves toward the low-pressure land area.
<span>Ø<span> </span></span>Land Breeze<span>: a local wind that blows from the land toward water</span>
<span>§<span> </span></span><span>Occurs because land cools faster than water – The low pressure (less dense) air is now over the water. The warm less dense air rises so the cooler air from the land moves toward that low pressure area by the water.</span>
10^8 just makes it easier to write out big numbers. It makes it so you don't have to keep writing out the really long number over and over.
If you were wondering.
3.0 * 10^8=300,000,000.0
The formula of the volume for a cylinder is pi*r^2*h. Given the diameter of 1 inch and height/length of 2.5 inches, the volume is calculated by:
V = pi*(0.5^2)*2.5 = 1.9625 in^3
the cork density is 0.26 g/mL, since the units of the volume is in^3, convert to cm^3 or mL:
1.9625 in^3 * (2.54cm/1in)^3 = 32.16 cm^3
So, the mass of the cylindrical cork is 0.26 g/mL * 32.16 cm^3 = 8.36 g
Answer:
1.044 g sample contains only vitamin C (C6H8O6) and sucralose (C12H19Cl3O8). When the sample is dissolved in water to a total volume of 33.0 mL, the osmotic pressure of the solution is 3.69 atm at 295 K.
