The entire Earth is influenced by energy from the sun.
Answer:
Dissolved Oxygen and Water. Although water molecules contain an oxygen atom, this oxygen is not what is needed by aquatic organisms living in natural waters. A small amount of oxygen, up to about ten molecules of oxygen per million of water, is actually dissolved in water. Oxygen enters a stream mainly from the atmosphere .
Explanation:
I want to investigate how temperature affect the concentration of oxygen in air as it will affect how much oxygen we inhale per breathe. Oxygen by percent composition in air is 20.95%. However, the oxygen concentration/density in air varies due to the expansion of gas particles and varies inversely wth temperature according to P/RT=n/V.
Answer:
456,881.78 miles
Explanation:
If there is a right angle among the Earth, moon and the sun, so , that mean that the triangle has a hypotenuse that represent the distance among the Earth and the Sun.
Also, there is another data, the adjacent side of this triangle, the distance among Earth and the Moon.
So with the adjacent side, the right angle, and the hypotenuse, we can work with the geometrical calculation that it is called, cosine.
To obtain the hypotenuse will be:
Cos alfa = adjacent angle over the hypotenuse.
So, to obtain the Hypotenuse: Adjacent side divided into the cosene of 45 º (0.5253)
So, Hyp = CA/cos angle
Hyp = 240, 000 miles / 0.5253 = 456, 881.78 miles
