When a comet enters the solar system, it curves toward the sun. Which statement describes why the sun does not move when a comet is nearby?
Answers
Answer:
Explanation:
When a comet enters the solar system it curves towards the Sun due to the Sun's gravitational pull. Every celestial object in the universe has a gravitational pull whose force is dependent on the object's mass. The larger the object is the more gravitational pull it will have. The Sun is the largest object in our Solar system and therefore has the most gravitational pull. This is why the comet curves toward the Sun, but the opposite does not happen because the comet's gravitational pull is not strong enough to pull the Sun.

B : The density material is farthest from the center.
C : The densest material is near the center
D : Density differences allow Earth materials to mix freely. ( science by the way )
Answers
Answer:
Earth has layers because of density. Dense materials such as iron sank to the middle of the Earth, the center of its gravity. Less dense materials stayed at the top.
Explanation:
hope this help:)
The answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center
The earth is made up of different layers namely,
The crustThe upper mantleThe lower mantleThe outer core andThe inner core.Each layer goes from topmost to inner most and the density of each layer increases as we moves closer to the center of the earth.
So, the densest material is closest to the center.
So, the answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center

Answers
Answer:
The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

What is the ratio of the effusion rate of the helium to methane? (round to hundreds)
Answers
Answer:
2.00
Explanation:
From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.
Let the rate of effusion of Helium be R1
Let the rate of effusion of Methane be R2
Let the molecular mass of Helium be M1
Let the molecular mass of Methane be M2
Hence;
R1/R2 = √M2/M1
R1/R2 = √16.0294/4.0026
R1/R2 = 2.00
