Eₖ = √1/2 mv²
Eₖ/v² = 1/2 m
2Eₖ/v² = m
mgh = 1/2 mv²
gh = 1/2 v²
2gh = v²
v = √2gh
= √2 × 10 N/kg × 2 m
= 6.324 ms⁻¹
m = 9.8/(6424)²
= 9.8/39.993
= 0.245 g
I am not sure if it's correct.
i transposed for m in the first equation then to find the velocity I combined the potential and kinetic energy equation. there was no mass because velocity doesn't depend on the mass
Then I used earth's gravitational field strength (g) 10 N/kg and the 2 m was the height provided in the question
you can try working and see if you get the same
The most important economic goal that was associated with
the construction of the Three Gorges Dam the production of the hydroelectric
power. The water was going to be used as clean and renewable resource . Hydroelectric
is very clean since it does not emit any greenhouse gases when producing this
type of energy.
The correct answer for the question that is being presented above is this one: "layers of metamorphic rock that eroded and extruded from deep in the earth's crust. <span>The Columbia Plateau is a geologic and geographic region that lies across parts of the U.S. states of Washington, Oregon, and Idaho. </span>
Answer:
Judaism has not experienced widespread spatial distribution due to colonialism and imperialism.
Explanation:
A is not correct because the English managed to create the biggest empire in history, thus they managed to influence large parts of the world.
B is not correct because Christianity was spreading for several centuries by force and by using empires more often than not.
C is not correct because the Spanish managed to conquer a lot of territories, mostly in the Western Hemisphere, and they had a huge influence there.
D is not correct because the French managed to create an empire spreading on all continents (except Antarctica) and had big influence all over.
E is correct because Judaism has never spread through imperialism and colonialism, it actually spread through the forced migration of its followers.
Herbivores will have less to eat cause more to die off which in turn effects the the predators who eat such herbivores will also have less to eat in the both are be effected negatively
