4. The equation mgy for gravitational potential energy is valid only for objects near the surface of a planet. Consider two very large objects of mass m1 and m2, such as stars or planets, whose centers are separated by the large distance r. These two large objects exert gravitational forces on each other.The gravitational potential energy is U = − Gm1m2 r where G = 6.67 × 10−11Nm2/kg2 is the gravitational constant. (a) Sketch a graph of U versus r....
Multiple Choice Identify the choice that best completes the statement or a wer the question 1. One of the nearest stars is Alpha Centauri, whose distance is 4.4 light-years. The time it takes light to travel from Alpha Centauri to us is a 1.25 seconds b. 8.3 minutes c. 4.4 years. d. 600 years. 2. Which of the following is false? a The Local Group is a member of the Laniakea Supercluster, which contains thousands of galaxies. b. The Local...
Before leaving Alpha Centauri, you change from the shuttle to a light speed interstellar cruiser and head out deep into the galaxy to visit another binary star system - but this one is composed of dead stars! To occupy your waking travel time by reading about this star system in the "Outer Space Tourbook": Stars spend most of their lifetimes undergoing nuclear fusion in their cores, which is why they give off so much light. However, when the material necessary...
Astronomy Ranking Task: Star Evolution & Lookback Time Exercise #1 Description: Imagine that the four stars listed below all became Main Sequence (MS) stars at exactly the same time 10 billion years ago but in different locations of the universe. Cosmo Star is an O spectral class star with a MS lifetime of 3 million years. Its life will eventually end as a SN type II and become a black hole. Cosmo Star is located in a galaxy 10 billion...
10) 1. A 50 kg object is placed between a 400 kg and a 900 kg objects which are separated by a distance of 2 m. (a) What is the net gravitational force exerted on 50 kg object by the other two? (b) At what position the 50 kg object be placed so the net force on it will be zero? (10 2. Compare the gravitational forces between the moon and the earth and the moon and the sun if...
choose correct answer. no explanation needed QUESTION 36 What does the apparent magnitude of a star tell us about that star? its mass how bright it appears from Earth its radius how much energy it is emitting QUESTION 37 What is the reason sunspots appear darker than surrounding regions on the Sun's surface? They actually are fairly bright, but appear dark against the even brighter background of the surrounding photosphere. They are too cold to emit any visible light. They...
