which of the following is one of the things used to determine the age of the universe?

speed of light of other galaxies

gravity of other galaxies

radiation of other galaxies

distance from Earth to other galaxies

Answers

Answer 1

Answer:

Explanation:

Astronomers estimate the age of the universe in two ways:

1) by looking for the oldest stars.

2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.

Answer:

✓When the Moon passes between the Sun and the Earth and blocks the sun.

A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface.

Thanks for the question,

The molten rock from the cloth exploded next to the hole, forming a new crust. Earthquakes occur in these areas, called distribution centers, are minimal. The Great Rift Valley in Africa, the Red Sea and the Gulf of Aden were all formed as a result of the movement of various plates.The changing plate border is the area where two tectonic plates move to each other, often causing one plate to slide under the other. A collision of tectonic plates could lead to earthquakes, mountains, mountain construction, and other geological events.When two tectonic plates slide past each other, the area where they meet is a rotating or lateral error. The San Andreas Fault is one of the best examples of lateral plate movement.The air, water, and ice erode and shape the earth. Volcanic activity and earthquakes are changing the landscape in a dramatic and often violent way. And with more time, the movement of the plates of the earth also exposes the oceans and continents.

Why are there so many small, fractured thrust faults near Los Angeles? What does this mean in terms of earthquake probability for this city?

Answers

Answer:

The blind thurst faults of Los Angeles and San Andreas are formed due to the movement of the two tectonic plates the North American and Pacific plate. These two tectonic plates or the crust of the earth did not colloid but slide past each other and formed the fault that is present in San Andreas and Los Angeles.

Los Angeles is at high risk or more chance of earthquakes as these faults, formed due to the activity of plate tectonic, released energy by their rapid movement on active faults.

Answer:

Apartheid was a historical period of state-determined and organized racial segregation in South Africa. It was characterized above all by the authoritarian, self-declared predominance of the “white” population group of European descent over all others. It began at the beginning of the 20th century, had its high phase from the 1940s to the 1980s and ended in 1994 after a phase of mutual understanding with a democratic change of government in which Nelson Mandela became the country's first black president.

Thus, during Apartheid there was a clear racial differentiation, which was reflected in services of different categories for whites and blacks, segregating public services, limiting the right to vote of black people and, in general, relegating black people to a kind of second-class citizenship with respect to whites, which led to the emergence of revolutionary movements such as the one led by Nelson Mandela.

In essence, this South African Apartheid was a replica of the racial segregation that occurred in the southern United States after 1877, with the fundamental difference that in the South African case this segregation was federal, that is, accepted by the government of the nation, while in the case of the southern states this segregation was imposed by the state governments.
