Star A is 125 times brighter than Star B how many times hotter is Star A than star B

Answers

Answer 1

Answer:

Star A is 3.343 times hotter than star B.

Explanation:

It is known that the luminosity of a star is proportional to its effective temperature to the 4th power. This means that the ratio between the brightness of stars A and B is equal to the ratio between their temperatures to the 4th power:

[tex]125=T^4\\T=\sqrt[4]{125}\\T=3.343[/tex]

Star A is 3.343 times hotter than star B.

What is Nigerian English?

Nigerian English, also known as Nigerian Standard English, is a dialect of English spoken in Nigeria. Based on British English, the dialect contains various loanwords and collocations from the native languages of Nigeria, due to the need to express concepts specific to the culture of the nation.

Nigerian Pidgin, a pidgin derived from English, is mostly used in informal conversations, but Nigerian Standard English is used in politics, formal education, the media, and other official use. There are three main dialects of Nigerian English: Hausa English, spoken by the Hausa,  Igbo English, spoken by the Igbo and Yoruba English spoken by the Yoruba. Nigerian English is a nativized form of English. Like South African English, its nativization and development as a New World English correspond roughly with the period of colonization and post-colonization by Britain.

Nigerian English became a nativized language that functions uniquely within its cultural context.

The fishing industry of Maldives was destroyed in 2004 because of the tsunami. Hence, Option C is correct.

What is a tsunami?

The Japanese term for the wave is "nami," while the word "tsu" means harbor. Tsunamis are waves brought on by the abrupt movement of the ocean's surface as a result of aftershocks, underwater landslides, landfalls into the water, powerful eruptions, or meteorite impacts.

The earliest tsunami ever observed happened in 479 BC. A Persian army that was advancing on the Greek town of Potidaea was wiped out. In his work Chronicle of the Peloponnesian War (3.89.1-6), the Greek historian Herodotus questioned the causes of tsunamis as early as 426 BC.

In 2004, this ranks one of the ten worst earthquakes and the worst tsunami in the recorded track record when it comes to the number of lives killed.

Thus, Option C is correct.

Explain Pangaea, Pannotia, Laurasia, Gondwana, and any other supercontinents that have been theorized.

Answers

In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass.However, some earth scientists use a different definition: "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times although a minimum of about 75% of the continental crust then in existence has been proposed as a limit to separate supercontinents from other groupings.

Supercontinents have assembled and dispersed multiple times in the geologic past According to the modern definitions, a supercontinent does not exist today. The supercontinent Pangaea is the collective name describing all of the continental landmasses when they were most recently near to one another. The positions of continents have been accurately determined back to the early Jurassic, shortly before the breakup of Pangaea The earlier continent Gondwana is not considered a supercontinent under the first definition, since the landmasses of Baltica, Laurentia and Siberia were separate at the time.

8. At what water depth will the wave described in Question 7 begin to break? 9. What two factors determine how far from the shoreline waves will begin to break?

Answers

Answer:

After reaching 1.3 times the height of the wave, the wave will break.

Explanation:

The wave will break when it reaches a water depth of 1.3 times the height of the wave. The two factors are depth of the seafloor and height of the wave determine how far from the shoreline waves will begin to break. when the depth of the seafloor decreases so the waves touches the ground and the wave is starting to break. The wave will start to break when the ratio between the height of the wave and wavelength of the wave is 1 : 7.

The wave will begin to break after reaching 1.3 times the height of the water depth.

A wave simply means the disturbance that transfers energy from one point to another in a medium. From the complete question, the wave will break when it reaches a water depth of 1.3 times the height of the water depth.

Also, the factors that determine how far from the shoreline waves they will begin to break are the depth of the seafloor and the height of the wave.

In conclusion, when there's a decrease in the depth of the seafloor, the waves touch the ground and the wave is starting to break.

Explain why is Russia so sparsely populated. (4) ATLEAST 4 POINTS ON WHY IT IS SPARSELY POPULATED PLZ!!!! I WILL GIVE BRAINLIEST

Answers

Explanation:

The Russian Far East wasn't connected to the rest of Russia by roads until early 20th century when the Transcontinental Railroad was completed. Until then, you either had to travel by ship around the entire Eurasia or go by horse drawn sleds in winter - either way the journey would take many months. So the distance itself proved a major hindrance to development and settlement of the region.

The Russian's actually a lot of plans and imagination initially. The Amur was sometimes called "the Russian Mississippi" - a river flowing through a fertile valley and riverine traffic connecting the region to the Pacific ocean. In reality, the Amur isn't at all like the Mississippi. It is frozen for at least 5 months of the year, and its delta is very shallow, prohibiting oceangoing ships from entering the river. Even the much more southerly Vladivostok relies on icebreakers to keep its port usable in winter months.

Answers

Answer:

1) 100%

2) Lose.

3) Entropy.

The second law of thermodynamics states that no process is 100% efficient. Thus, every system in the universe has a specific amount of energy in it. As the system functions, it will lose energy and gain entropy.

Explanation:

The second law of thermodynamics, also known as the entropy law or heat engine law, states that the total entropy of an isolated system can never decrease over time. It either increases (for irreversible processes, that is, most real life processes) or it remains constant (for reversible processes).

This translates to an expected loss of energy for any real life process thereby making it impossible for any process to be 100% efficient. This all then leads to entropy increase (a gain of entropy).
