The early precambrian atmosphere consisted primarily of nitrogen and carbon dioxide with almost no oxygen. 

<span>Today, the atmosphere contains about 20% oxygen, less carbon dioxide and similar amounts of nitrogen. </span>

<span>Photosynthetic green-leaf plants and trees are largely responsible for the change, converting carbon dioxide to oxygen.</span>

2. A 0.5 kg tennis ball has speed of 15m/s. what is the kinetic energy of tennis?
Talja [164]

Explanation:

Given

mass (m) = 0.5 kg

velocity (v) = 15 m/s

Now

Kinetic energy

= 1/2 *m*v²

= 1/2 * 0.5 * 12²

= 0.5 *0.5 * 144

= 36 joule

hope it will help

A gas sample occupies 4.2L at a pressure of 101 kPa. What volume will it occupy if the pressure is increased to 235 kPa
taurus [48]

1.8 L

<h3>Explanation</h3>

The volume of a gas, V, is inversely proportional to the pressure on it, P. That is:

V₁ · T₁ = V₂ · T₂.

Rearranging gives:

V₂ = V₁ · T₁ / T₂ = 4.2 × (101 / 235) = 1.8 L

How does technology limit the future of space exploration? A. Scientists are able to work both with current and future technolog
GREYUIT [131]
The answer is most likely that the answer is B. Because Space is a dangerous place in which you need certain things to explore it. If you want to go to to Jupiter, for example you need lots of Oxygen, fuel, a good rocket, willing people and many more things, but there is a way technology can skip all that. the technology we have now is not capable of doing that though.
