As a result, it moves from a circular orbit of radius 7.5 x 106 m to an orbit of radius 7.7 x 106 m. What is the approximate change in gravitational force from Earth as a result of this change in the satellite's orbit? (Recall that Earth has a mass of 5.97 x 1024 kg and G = 6.67 x 10-¹1 N.m²/kg².) chstv m hbo library SUBMIT E bel

(a) What is the approximate force of gravity on a 70kg person due to the Andromeda galaxy, assuming its total mass is 1013 than of our Sun and acts like a single mass 2 Mly away? (b) What is the ratio of this force to the person's weight? Note that Andromeda is the closest large galaxy.
Respond to each statement, true or false: (a) No force of gravity acts on an astronaut in an orbiting space station. (b) At three Earth radii from the center of Earth, the acceleration of gravity is one-ninth its surface value. (c) If two identical planets, each with surface gravity g and volume V, coalesce into one planet with volume 2V, the surface gravity of the new planet is 2g. (d) One kilogram of gold would have greater value on Earth than on the Moon.
Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?
Exoplanets in eccentric orbits experience large temperature swings during their orbits. Suppose you had to plan for a mission to such a planet. Based on Kepler’s second law, does the planet spend more time closer or farther from the star? Explain.
With the aid of a diagram, explain how the Doppler effect can be used to detect the pres- ence of an unseen planet around a nearby star. State how an astronomer can determine if the planet is on a circular or eccentric orbit.

Question 10/17 > NEXT BOOKMARK A hot air balloon has a mass of 400 kg and is flying at about 6,400 km from the center of Earth. A satellite orbiting Earth 10 has a mass of 5,000 kg and is located, on average, at about 36,000 km from the center of Earth. Which statement compares the gravitational force of Earth on the objects? Choose the correct answer. A The gravitational force on the hot air balloon is about 0.08 times as strong as the gravitational force on the satellite. (B The gravitational force on the hot air balloon is about 0.4 times as strong as the gravitational force on the satellite. C The gravitational force on the hot air balloon is about 2.5 times as strong as the gravitational force on the satellite. D The gravitational force on the hot air balloon is about 32 times as strong as the gravitational force on the satellite.

Part B: Explain how mass and distance affect gravity. 1. How would increasing the mass of the Moon affect the force of gravity? 2. How would decreasing the mass of the Moon affect the force of gravity? 3. How would increasing the distance between Earth and the Moon affect the force of gravity? 4. How would decreasing the distance between Earth to the Moon affect the force of gravity? Part C: Based on this idea, why do you think the solar system is set up the way it is?
