Answers

Final answer:

The SI base unit for mass is the kilogram (kg), which is defined as the mass of a specific reference object. The gram (g) is a smaller unit of mass, equal to 1/1000 of a kilogram.

Explanation:

The SI base unit for mass is the kilogram (kg). It is defined as the mass of a specific reference object, which was originally one liter of pure water. In May 2019, the definition was changed to be based on fundamental physical constants. The gram (g) is a smaller unit of mass, equal to 1/1000 of a kilogram.

When the resultant force acting on a system is zero, the total momentum of the system...

Answers

When the resultant force acting on a system is zero, the total momentum of the system remains constant. This is known as the principle of conservation of momentum. In other words, if the net external force acting on a closed system is zero, the total momentum of that system will not change over time. This principle is commonly applied in physics, particularly in scenarios involving collisions and interactions between objects.

I took the test :)

Suppose you observe a binary system containing a main-sequence star and a brown dwarf. The orbital period of the system is 1 year, and the average separation of the system is 1 AUAU . You then measure the Doppler shifts of the spectral lines from the main-sequence star and the brown dwarf, finding that the orbital speed of the brown dwarf in the system is 22 times greater than that of the main-sequence star.

Answers

Final answer:

In a binary system with a main-sequence star and a brown dwarf, we can determine their masses by analyzing their radial velocity curve and measuring the Doppler shifts of their spectral lines. Kepler's law can then be used to calculate the sum of their masses.

Explanation:

The question is about a binary system containing a main-sequence star and a brown dwarf. We can determine the masses of the stars in a spectroscopic binary by analyzing their radial velocity curve. By measuring the Doppler shifts of the spectral lines, we can calculate the orbital speed of each star and use Kepler's law to calculate the sum of their masses.

Final answer:

The orbital speed and separation of a binary system composed of a main-sequence star and a brown dwarf can be utilized to infer their respective masses. This is accomplished by studying the Doppler effect from the spectral lines of the system and applying Kepler's third law. Greater mass is found to exhibit slower orbital speed.

Explanation:

The main-sequence star and the brown dwarf form a binary system with an orbital period of 1 year and an average separation of 1 Astronomical Unit (AU). The Doppler shifts of the spectral lines from the main-sequence star and the brown dwarf indicate that the orbital speed of the brown dwarf in the system is 22 times greater than that of the main-sequence star.

We can estimate the masses of the stars in this binary system using the formula based on Newton's reformulation of Kepler's third law: D³ = (M₁ + M₂)P², where D represents the semimajor axis in AU and P represent the period in years. From this, we can calculate the sum of the masses of the two stars. Given the difference in orbital speeds, the main-sequence star has a higher mass to result in a slower speed, and the brown dwarf has a smaller mass to result in the higher speed.

In conclusion, by analyzing the radial velocity curve and using Kepler's third law, we can estimate the masses of the stars in a binary system.
