What is the difference between geocentric versus heliocentric models of our solar system?

Question 1: What is the difference between geocentric versus heliocentric models of our solar system? 1 paragraph Question 2: If there is gravity where the International Space Station (ISS) is located above Earth, why doesn’t the space station get pulled back down to Earth? Can we use this same concept for the Earth orbiting the… Continue reading What is the difference between geocentric versus heliocentric models of our solar system?

Write a paragraph explaining the location of the Stars plotted and whether that

Write a paragraph explaining the location of the Stars plotted and whether that matches their Roman Numeral designations such as V, lV, lll, ll, lb and la and Vl. Then explain Sub-Giants, Giants, Bright Giants, Less-luminous Supergiants, Brightest supergiants and White Dwarves and where their expected locations are on the HR Diagram. Based on the… Continue reading Write a paragraph explaining the location of the Stars plotted and whether that

For this project you are going to observe some light sources. You are going to observe the SPECTRA of those light sources. If you have a spectroscope, use that. If not, you can find a poor-man’s spectroscope in the form of a DVD or CD. The DVD does the same job as the diffraction grating… Continue reading For this project you are going to observe some light sources. You are going to o

The term paper is a chance for you to bring the key points you learned in the course all together into one scientific argument. Make a scientific argument about whether or not you think the Webb Observatory (or another current mission such as Perseverence) will discover life. Your argument should show significant understanding of: The… Continue reading The term paper is a chance for you to bring the key points you learned in the co

Ch. 19 Study Questions 1. Explain the “cosmological redshift” (which is not the same as Doppler red shift). 2. Why doesn’t the expansion of the universe cause Earth and your body to expand? 3. From Earth, we see all distant galaxies flying away from US. What would you observe if you were located in one… Continue reading Ch. 19 Study Questions
