"Which is characteristic of globular star clusters"?

Andrew [12]

Answer:

Old age and hundreds of thousands of stars, only about 30 ly wide

Explanation:

A globular cluster is a collection of stars which are bound by a very strong force known as gravity (gravity is the force of attraction between two bodies). The gravity then causes globular clusters to have a spherical shape with a high number of stars closer to the center (where the gravity is strongest).

These stars are usually very old and the diameter of the clusters are usually only 30 lightyears wide because of the strong gravity.

In which of the following environments would you expect lithogenous sediment tobe the dominant sediment type? Choose all that ap

xeze [42]

Answer:

Options (A), (B), and (D)

Explanation:

The lithogenous sediments are usually defined as those sediments that are produced from the weathering and erosion of rocks. These sediments are then transported from one place to another by agents such as wind, water, and ice. These are the most common sediments that are found on earth.

These sediments are of variable sizes, ranging from fine-grained sediments to coarse-grained and they are abundantly found in the sandy beaches, abyssal plains and at the base of the continental slope.

The rocks at the beaches are continuously hit by the sea waves that break down and carry the sediments seaward. These sediments along with the other terrestrial sediments are deposited on the abyssal plains and base of the continental slope.

Thus, the correct answers are options (A), (B), and (D).

How do the United States and eastern Mediterranean nations compare ?

WARRIOR [948]

Answer:

Turkey's strategic position directly influences U.S. policies vis-?-vis Iran, Iraq, Syria, and the Caucasus.

It has a growing strategic relationship with another long-term American ally, Israel, and it controls access to the Black Sea.

The successful exploitation and security of Caspian oil and natural gas reserves will certainly involve the transport of energy resources through Turkey, either overland or through the Bosporus, or both.

Turkey is a Muslim democratic country. The successful melding of Islam with a democratic, Western-oriented government serves as a model for many other nations in the region.

With regard to Greece, the strategic importance of the country has increased because of events in the Balkans over the last 10 years. Greece is certainly the most stable and economically viable country in that region. Greece's role in the region's development will grow even more as Balkan countries continue to struggle with their future.

The distance from Alexandria to Syene is about 500 miles. On the summer solstice the sun is directly overhead at noon in Syene.

svp [43]

Answer:

Earth circumference is 25000 miles

correct option is 25,000 miles

Explanation:

we have given here Alexandria to Syene distance = 500 miles

the sun is 1/50th of the circumference of the sky (about 7°)

as we know that Earth circumference done by astronomer Eratosthenes in 240 B.C

He observe on a particular time of day ( in noon) during the summer solstice

and there was no shadow in Syene in Egypt so This was verified that the sun must be directly on overhead and not at an angle to the surface of the city at that time

so

In Alexandria he measured the position of sun at the same time and found it to be nearly (1/50)th of a complete circle

it would be 7.2 degree (when we do $\frac{360}{50}$ = 7.2)

so 2 reference points being 2 cities for the sun

all measure circumference = the distance between these two cities × 50

and we have given 500 miles

so

Earth circumference = 500 × 50

Earth circumference is 25000 miles

correct option is 25,000 miles
