B. Closed, because you can't call it isolated because your not isolating the jar, plus the jar is nether connected or opened. Hope that helps!
<span>The amount of solar energy available varies by location on earth, the time of the day at that location, the season and weather conditions. Rain, fog, and clouds will lower the amount of solar power available to gather and there are fewer hours of sun available in different seasons (winter for North America). To gather solar power, you also need a large area. This can be lessened by conditions such as snow, so that even on a sunny day, covered panels will collect less energy.</span>
<span>The reason why the shapes of the continents as of
today do not perfectly fi into to super continent because long time ago the
super continent was scattered into pieces. And as times go by, those smaller
parts of super continents undergo soil erosion caused by the water and other
way that causes their original shapes change.
Thus, if we are going to judge now if those smaller part of super continent,
they’re no longer gonna fit perfectly because through time their original form
changed</span>
Answer:
Word for the first blank: gravity
Word for the second blank: matter
Explanation:
The only way debris from the impact with Earth can be held close to Earth is due to a force. The only force that could be acting from Earth is "the force of gravity".
The gravitational pull of this new object being formed, increases proportional to its mass as more and more "matter" accumulates. And the accretion process is now on its way.
<span>It’s 2/5 MR^2 where M is mass and R is the radius of the bas</span>
