Question

Астрономия. Вычислите, во сколько раз скорость звезды Девы превышала бы скорость света, если согласно геоцентрическим воззрениям она в суточном обращении двигалась бы в плоскости земного экватора на расстоянии 1015 км от Земли. Помогите пожалуйста. Срочно!​

Answer 1

Ответ:  Скорость звезды превышала бы скорость света в ≈ 242 раза

Объяснение:  Если расстояние (S) до звезды равно указанному в вопросе, то длина орбиты звезды была бы L = 2πS = 2*3,141159*10^15км.

 Такое расстояние звезда пролетала бы за одни сутки.  В сутках содержится Tс = 24*60*60 = 86400  = 8,64*10^4 секунд.

Следовательно скорость звезды была бы

U = L/Tc = 2*3,141159*10^15/8,64*10^4 = 7,2722*10^10 м/с

Скорость света 3*10^8 м/с.   Значит, скорость звезды была бы больше скорости света в 7,2722*10^10/3*10^8 ≈ 242 раза

Answer 2

According to the geocentric model, which assumes that the Earth is at the center of the universe, the speed of the star Virgo would depend on its distance from the Earth and its orbital period. To calculate the speed of the star, we need to know the distance of the star from the Earth and the time it takes to complete one orbit.

Unfortunately, I couldn't find specific information about the distance of the star Virgo from the Earth or its orbital period in the search results. However, I can provide you with some general information about the speed of stars and the speed of light.

The speed of light is approximately 299,792 kilometers per second in a vacuum. It is considered to be the fastest speed possible and is denoted by the symbol "c".

The speed of stars can vary depending on their distance from the Earth and their orbital motion. Stars in our galaxy, the Milky Way, typically have speeds ranging from a few kilometers per second to a few hundred kilometers per second.

To calculate the ratio of the speed of the star Virgo to the speed of light, we would need the specific values for its distance from the Earth and its orbital period. Without this information, it is not possible to provide an accurate calculation.
