The images show two culturally significant locations. Jerusalem is a pilgrimage site for adherents of Islam, and Bodh Gaya is a pilgrimage site for followers of Buddhism.
Using the images shown, describe TWO differences between the cultural landscapes of these pilgrimage locations.
The difference in the images is the presence and absence of sculptures and the geometric shapes of the religious temples.
We can arrive at this answer because:
Jerusalem is a holy place for Muslims, Jews, and Christians as they represent a place of worship to the same God.The God of these three religions is not represented by sculptures and for this reason, there are no sculptures in the time shown in the image.Furthermore, it has rectangular and round geometric shapes, emphasizing straight and curved lines.Buddhism, on the other hand, has Buddha as its main representation and so we can see a giant sculpture of it in Bodh Gaya.The temple at Bodh Gaya is triangular and emphasizes slanted, pointed lines.Thus, we can recognize that in addition to cultural differences, the two regions have strong religious differences.

The length of a shadow of a building is 30m The distance from the top of the building to the tip of the shadow is 38m Find the height of the building. If necessary, round your answer to the nearest tenth.
Answer:
23.3m
Explanation:
If you use the Pythagorean theorem to solve this, think of the tip of the building to the tip of the tip of the shadow as the hypotenuse then set it up like this, 30^2+x^2=38^2
subtract 30^2 from each side to get x^2=38^2-30^2
x^2=544
x=[tex]\sqrt{544}[/tex]
x=23.32380
x=23.3m

An atom of the element chromium has an atomic number of 24 and a mass number of 52. How many electrons are in an uncharged atom or chromium.
Answer:
24
Explanation:
Given parameters:
Atomic number = 24
Mass number = 52
Unknown:
Number of electrons in the uncharged atom of chromium = ?
Solution:
In an uncharged atom of chromium, the number of protons and electrons are the same.
Once we can find the number protons, we can simply equate it to the number of electrons.
Atomic number is the number of protons in an atom. Therefore, since the atomic number is 24, the number of protons likewise is 24;Number of electrons is 24

A farmer dug a well but did not find any water.
Which most likely explains why the farmer did not find water?
The water table is deeper than the well.
All the groundwater is flowing out of a spring.
The well is being dug between two vertical, impermeable layers.
The well is located where groundwater is stuck between impermeable layers.
Answer:
The water table is deeper than the well.
Explanation:
The most likely reason why the farmer could not find any water is that the water table is deeper than the well.
Water table is a zone in the subsurface below which water fills pore spaces in the soil or rock.
Above the water table is the zone of aeration. Below this zone, water is found in the pore spaces. To source for ground water, wells must intersect the water table for them to be a prolific source of water.Answer:
