- 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 axisIf 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?
- A typical comet contains some 1013 kg of water ice. How many comets would have to strike Earth in order to account for the roughly 2×1021 kg of water presently found on our planet? (Hint: simple division) If this amount of water accumulated over a period of 500 million years, how frequently must Earth have been hit by comets during that time? (Hint: Calculate, on the average, how many comets hit the Earth per year during that time.)The material ejected from the surface of asteroid would have a significant momentum. Since asteroid and all its material is _____, the ejection would cause _____ change in momentum of the asteroid, according to the ____. The ejected material is analogous to _____, and the asteroid is analogous to ____. Fill in the blank -oppositely directed -law of conservation of energy -gases expelled from a rocket -an isolated system -a rocket -law of conservation of momentum -perpendicularly directedWhy do we see comet Halley only every 76 years?
