Solved in 3 steps
- The mass of an average comets nucleus is about 1.0 x 10^14 kg. If the Oort Cloud contains 20 x 10^11 comet nuclei, what is the mass of the clouds in units of Earth masses? (Note: Earths mass is 5.97 x 10^24 kg) _______ m compare that with Uranus's mass. (Note: Uranus's mass im units of Earth's mass is 14.5m) mass of the Oort Cloud/mass of Uranus:_____Annual meteor showers occur when the Earth passes through the orbital path of acomet. The intensity of these showers vary from year to year. Which of the following may bethe reason for this? Group of answer choices - Meteor showers are not caused by comet debris - Sun's temperature - en distribution of debris along comet's orbit - Earth's rotation axisRe-order the numbers so the events occur in the correct order, with the oldest event as number 2, and the youngest event as number 13. 2. Now at roughly 100% of present-day mass and the asteroid bombardment over, Earth begins cooling and differentiating. As the outer layer of the Earth cools and solidifies, lighter elements and compounds rise to the surface while the denser ones sink to the core 3. The now differentiated ice, gas, and dust of the solar accretion disc conglomerates together into asteroids from gravity 4. "The Big Whack" A Mars-sized protoplanet we call Theia collides with primitive Earth, adding even more energy and mass 5. The Big Bang 6. As the early atmosphere cools, water vapor is eventually cool enough to condense into liquid water, eventually covering the planet in an ocean 7. The debris from the collision of Earth and Theia produce a ring in orbit. This ring eventually coalesces into the Moon, just as Earth coalesced from the solar accretion disc 8. A nebula…
- If the velocity of the Solar Wind about 4.0 x 10^2 km/s and the visible tail of a comet of 9.0 x 10^8 km long, how many days does an atom in the solar wind take to travel from the nucleus to the end of the visible tail? (note: 1 day= 86,400 sec) _______ daysWhat is the evidence that suggests asteroids might have geologically active surfaces?suppose that the oort comet cloud contains 10^12 comets, with an average comet diameter of 10km. Calculate the mass of a comet 10km in diameter, assuiming that it is composed mostly of water ice (density of 1g/cm^3). Next calculate the total mass of the comet cloud. finally, compare this mass with that of the Earth and Jupiter.
