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:
C. Resource partitioning of the seeds reduces competition, and the five different species can live in the same tree
Explanation:
Generally, living organisms tend to compete for resources such as food and water. However, to restrict competition, resource partition is used. Resource partitioning is the breaking down of scarce resources to prevent competition in a niche. Therefore, as a result of resource partition that occurs due to limited resources, the competition among the species is reduced.
The Singapore we know today has a history marked by rapid transformations. Created initially by British political and economic interests, it was the local and world economic changes that proved to be the great spring of transformation of the country and its society.
A Brief Chronology
2nd century. First records of Singapore.14th century. Origins of the name of Singapore, Singapore or "City of the Lion".1819. Sultanate of Johor allows the installation of a British commercial warehouse on the island.Second World War. Japanese invade the British colony.1955. Self-government for Singapore.1958. Birth of the State of Singapore.1963. Singapore integrates Malaya into Malaysia.1965. Singapore is no longer part of Malaysia. The Republic of Singapore is born.The Primors
The earliest records about Singapore are from the second century where it appears on a map created by the mathematician, astrologer and geographer Ptolemy. In the third century there are Chinese accounts in which it is termed "Island at the End", a reference to its location at the extreme end of the Malay Peninsula.
The name Singapore had its origin in the 14th century, when the Prince of Srivijaya when visiting the region would have seen a lion (something very unlikely for the region, which was inhabited by tigers and not lions). After this supposed encounter, the region happened to gain the name of Singapore, that in Sanskrit means City of the Lion (singa = lion and pure = city).
Answer:
D:The rock that shifted to cause earthquake B released more energy
Explanation:
The magnitude of an earthquake is a function of the intensity of the earthquake and energy it releases.
An earthquake is a sudden movement within the earth which causes a release of energy.
- The magnitude of earthquakes is reported by the intensity of the quakes from the source.
- Earthquakes with a high intensity will have a high energy.
