Answer:
Population- China
Land area- Russia
Population Density- Japan
Crowded- Japan
Explanation:
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
Answer:
unablity to provide all services for all people
greater poverty and lack of sanitation
greater air pollution with significant impact on human health
The city-states of ancient Mesopotamia were independent cities constructed around temples and entirely self-contained within mighty perimeter walls.<span> City-states were unified with each other only by their shared use of the Sumerian language. They spent most of their time engaged in conflict over resources.</span>
It is false that scientists are able to determine the relative age of rocks in specific years. This is because relative age refers to how much <span>one layer is older or younger than another layer but does not indicate the rock's age in years, but perhaps in centuries at most. Scientists can, however, determine the absolute age of rocks using radiometric dating. </span>
