If, as is typical, each of them breathes about 500 cm3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year? if, as is typical, each of them breathes about 500 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year?

Volume of brethe consumed in a normal breathe is known to be tidal volume. The tidal volume of a person is 500 mL. There are 12 times a person can breathe in a minute.

Number of breathes in a minute

Consumption of air per brethe

Consumption of air per minute =

Consumption of air per year

Thus, 31.53 * 10^5 L of air consumed in a year by an astronaut.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
