Anne releases a stone from a height of 2 meters. She measures the kinetic energy of the stone at 9.8 joules at the exact point it hits the ground. What is the mass of the stone?
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

Ground shaking can transform wet sediments into liquid-like slurries in a process known as ________.
The process of liquefaction, which is caused by ground shaking, can turn wet sediments into slurries that resemble liquids.
What does ground shaking mean?The vibrating of the ground caused by an earthquake is referred to as "ground shaking." Body waves and surface waves are responsible for ground trembling. According to a general rule, the severity of ground shaking rises as magnitude rises and falls as distance from the causing fault rises.
Any structures that are in the path of these surface waves may bend or topple over due to the movement. On steeper hills or mountains, the ground shaking may also trigger landslides, mudslides, or avalanches, all of which can harm people and inflict property damage.
The type of building a person is in may transmit the shaking more than another type, which explains why one person close may feel an earthquake while another does not.

what caused the change in the air and soil temperature between 20 and 50 years after the field was abandoned
Industrialization is a process that brought negative influences on the earth's natural environment. One of them is climate change.
Industrialization was a process in which the production processes of different products were improved allowing the manufacture of more units with the following characteristics:
Less time wasted.Lower spending of money.Higher performance.Industrialization influenced most of the countries of the world and caused the great displacement of people from rural areas to cities. This displacement was because the agricultural and manual products produced by artisans and peasants could not compete in the market with the products of large industries.
After several years, humans have shown the negative consequences of this industrialized growth. Well, many of the machines used in these factories work with the combustion of fossil fuels, and the gases produced by them are released into the atmosphere.
On the other hand, the overproduction of products and the effects of marketing has increased the demand for unnecessary products with a very short useful life that increased human waste that pollutes nature.
These environmental damages were intensified by the action of the greenhouse effect because this phenomenon naturally balanced the Earth's temperature, but with the increasing production of gases in factories and other industries, there is a greater concentration of these gases in the atmosphere, which has led to progressive heating of the air and soil.

Why geography does not have unique definition and consensus among Geographers? Write the reason in accordance with the thoughts of geography.
Because geography is such a large and all-encompassing discipline, as you can see from the definitions, it is difficult to define. It is much more than just studying maps and physical elements of the land since humans are impacted by and influence the land.
The reason why geography does not have unique definition and consensus among Geographers is because:
It is too broad.Geography is the study of everything that is on the surface of the earth and they can be classified into:

Which type of rock is pegmatite?
A. Extrusive igneous
B. Sedimentary
C. Metamorphic
D. Intrusive igneous
Answer:
D. Intrusive igneous
Explanation:
Diorite, granite, pegmatite are examples of intrusive igneous rocks. Extrusive igneous rock: These rocks erupt onto the surface resulting in small crystals as the cooling takes place quickly. The cooling rate is for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock.
Answer:
It is in fact D. (Intrusive igneous)
Explanation: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite.
