Which type of telescope would perform better on a mountaintop than at a lower elevation?

marishachu [46]

when an optical telescope located on the ground is used to view the sky the image has to surpass through the earth's atmosphere which is polluted. so the resolution wont be clear. When viewed on a mountain top both optical and infrared telescopes would perform better as the air above the atmosphere is less depth and cleaner.

A resting adult requires about 240 ml of pure oxygen/mind and breathes about 12 times every minute. if inhaled air contains 20 p

Dmitry_Shevchenko [17]

12 times breathe give 240 ml of pure $O_{2}$ . Each breathe gives 20 ml of $O_{2}$ .

Let us consider, volume of air per breathe= x ml.

Pure $O_{2}$ from inhaled air= $\frac{20}{100}x$ ml and Pure $O_{2}$ from exhaled air= $\frac{16}{100}x$ ml.

Pure $O_{2}$ from inhaled and exhaled air= 20 ml

So, $\frac{20}{100}x$ + $\frac{16}{100}x$ = 20

Therefore, x = 55.5 ml

So, volume of air per breath= 55.5 ml.

In principle, the equilibrium in the dehydration of an alcohol could be shifted to the right be removal of water. Why is this ta

Trava [24]

Answer:

See explanation

Explanation:

In this case, we have to remember that if we want to remove water from the reaction vessel we have to heat the vessel. So, we can convert the liquid water into gas water and we can remove it from the vessel. In this case, the products of dehydration for both molecules are (E)-4-methylpent-2-ene and cyclohexene with boiling points of 59.2 ºC and 89 ºC respectively. The boiling point of water is 100 ºC, therefore if we heat the vessel the products and water would leave the system, and the products would be lost.

See figure 1

I hope it helps!
