A newly discovered solar system is found 600 billion kilometers from the sun. How many AU
Scorpion4ik [409]
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers

1 billion=1,000,000,000
600 billion=600,000,000,000

</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's

the unicellular spores of the fern ceretopteris richardii are about 100 um in diameter.calculate the surface-area-to-volume rati
WINSTONCH [101]
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²

Volume = l³
Volume = (100 x 10⁻⁶)³

Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴

Which statement BEST characterizes the general relationship between air pressure and elevation?
Ad libitum [116K]

Both have an inverse relationship.


Explanation:

The two have an inverse relationship, that is, when elevation increases, atmospheric pressure decreases.

This is due to the amount of air on top of you at your current elevation.

At lower elevations, you have more air above you, and thus more pressure.

At higher elevations, you have less air above you, and thus less pressure.


At high elevation food takes longer time too cook due to low pressure, so at high altitude pressure cooker is used to cook food.


OK, :)
