- Four small spheres of mercury coalesce to form a single sphere. Compared with the combined surface area of the smaller spheres, the surface of the big sphere is Chose the correct answer: more. triple than the small spheres. double than the small spheres. less.Far into the future scientists are exploring a new planetary system in hopes of finding an Earth-like planet. In this system they find a planet with five moons, and they decide to study these moons in order to learn more about the planet. Here's what they find: • Moon A orbits the planet once every 2.3 days in a circular orbit with a radius of 7.87x107m. • Moon B has a highly elliptical orbit with an average orbital radius of 1.56x108m that takes 6.4 days. • Moon C has a speed of 1550 m/s in its circular orbit of radius 2.03x108 m. • Moon D has an orbital period of 10.9 days with an average orbital radius of 2.23x108 m. • And Moon E seems to get four times further than Moon B does at their furthest point from the planet. Scientists observed that half its orbit took 25.6 days. Use this data to make a linear plot such that you can use the slope of the line to find the mass of the planet. You may plot quantities such as distances, speeds, or periods, or any powers of those quantities, and…1. How is uniform circular motion different from other types of curved motion?
- What is the surface gravity (local acceleration) of a planet with a mass of (3.5×1024kg) that has a radius of (2.2×106m)?6 Why isn't there a planet where the asteroid belt is located? A The temperature in this portion of the solar nebula was just right to prevent rock from sticking together. B C D There was too much rocky material to form a terrestrial planet, but not enough gaseous material to form a jovian planet. There was not enough material in this part of the solar nebula to form a planet. Gravitational tugs from Jupiter prevented material from collecting together to form a planet. E A planet once formed here, but it was broken apart by a catastrophic collision.If the moon had an ocean as deep as the Earth’s, tides there would be about as high as tides on the Earth. Select one: a. False b. True
- A synchronous satellite, which always remains above the same point on a planet's equator, is put in circular orbit around Mars so that scientists can study a surface feature. Mars rotates once every 24.6 h. Use the data of this table to find the altitude of the satellite. ___KmAccording to Lunar Laser Ranging experiments the average distance LM from the Earth to the Moon is approximately 3.85 × 10° km. The Moon orbits the Earth and completes one revolution in approximately 27.5 days (a sidereal month). How can the mass of the Earth be calculated using the information above? Select the correct statements. Select one or more: O a. Use Newton's third law. O b. Use Newton's first law. c. Use Coulombs law. O d. Use Newton's second law.Until recently, the term "planet" had no clear-cut definition. In August of 2006, leading astronomers established new guidelines and declared that Pluto is no longer a planet. Which of the following is either false or least consistent with the new guidelines? Group of answer choices Pluto is by far the largest known object in the Kuiper belt, while Eris is the largest known object in the asteroid belt. A planet must have cleared the neighborhood around its orbit. Pluto is automatically disqualified from being a planet because its oblong orbit overlaps with Neptune's. A planet must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape. Pluto and the asteroid Ceres are both now classified as dwarf planets.
