Which of the following statements about the cause of the phase of the Moon is correct? a) The phase of the Moon depends on the alignment of the Earth, Moon, and Sun, While half of the Moon is always illuminated by the Sun, it is not always the half that is facing the Earth. b) […]
Calculate the rotational velocity of Jupiter in kilometers per hour (km/h). Show your work. 40) Convert both of the rotational velocities you determined in questions 20 and 21 to miles per hour (mi/hr), then calculate how many times faster Jupiter rotates than the earth rotates. il km 0.62 mi] Show your work.
There is a one-earth mass planet orbiting an M5 star of 0.2 Mo and luminosity 1×10-2 Lo. A) How close does the planet need to be to the star in order to receive the same amount of energy as the Earth receives from the sun? (The solar flux is 1.386×10 erg s-] cm-?) B) What […]
This week let’s explore a strange place where time and space swap fundamental characters, inside a black hole. Start with this article https://www.space.com/what-happens-black-hole-center Links to an external site. and then research either a gravastar or a Planck star. Your original post should contain at least the most interesting things you found in your research as […]
You are looking at the top of the arc of a secondary rainbow, using a telescope, with the sun at your back. You are able to see and follow an individual raindrop, as it falls from the top of the rainbow to the bottom of the rainbow. Discuss and explain the color of the raindrop […]
Please provide written explanations for all conceptual questions. Could one please show all of their work for any mathematical calculations so I can understand? The diameter of the Sun is 1.4 106 km, and the distance between the sun and the Epsilon Eridani star is 10.47 ly. Calculate how many Suns it would take, laid […]
Start A Stellar Flowchart:: Decrease Word Bank 1. All stars begin in large 17. When a star’s core runs out Can need thinner once clouds of gas and dust are called: hydrogen and gravity begin Brown Dwarf collapsing the star. As the star Nebula uses, the pressure # Increase Decrease Increase Remains the same, and […]
Make a list of each main phase of the Moon, describing roughly when the Moon rises and sets for each phase. During which phase can you see the Moon in the middle of the morning? In the middle of the afternoon? 4. What are the advantages and disadvantages of apparent solar time? How is the […]
Question 1 1 pts Ancient civilizations had no idea what caused the ocean tides, or any idea what it was related to. O True O False D Question 2 1 pts The force of gravity between two objects increases as the distance between those objects increases. O True O False Question 3 1 pts In […]
The diameter of the Sun is 1.4 106 km, and the distance between the sun and the Epsilon Eridani star is 10.47 ly. Calculate how many Suns it would take, laid side by side, to reach the Epsilon Eridani star. Use scientific notation. At what distance is an object if its parallax, as measured […]
