There's a calculator in this planet earth just use that. It's easy
<span>B. God.....................................</span>
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:
The word region: an area or division, especially part of a country or the world having definable characteristics but not always fixed boundaries.
Explanation:
Geographers categorize regions in two basic ways: physical and cultural. Physical regions are defined by landform (continents and mountain ranges), climate, soil, and natural vegetation. Cultural regions are distinguished by such traits as language, politics, religion, economics, and industry.
Answer:
b.They separate markets, thereby increasing transportation costs.
Explanation:
Deserts and tropical forests seem to be opposites, but they all have separate markets, thereby increasing transportation costs.
Hope this helps!
