Answer: What's the DiDifference Between Asteroids & MeteoritesBy Karen S. Garvin, eHow ContributorSharePrint this articleAsteroids can become meteorites if they fall to Earth.Both asteroids and meteorites originate in outer space. Asteroids are small planet-like bodies that orbit the sun, and known as planetoids or minor planets. The asteroid belt that lies between Earth and Mars contains hundreds of thousands of these planetoids. Sometimes asteroids fall out of orbit and hit the Earth, and then they become meteorites. However, not all meteorites are asteroids, and meteorites may be from the Moon or another planet.Other People Are ReadingThe Characteristics of Comets, Meteors & AsteroidsWhat Kind of Sediment Is a Piece of Meteorite?AsteroidsAsteroids are small rocky bodies that orbit the sun. Between Mars and Jupiter is the asteroid belt, thought to be a planet that broke apart. Asteroids are inactive, which means they do not have ongoing geologic processes, such as plate tectonics or active volcanoes. An asteroid can become a meteorite if it escapes from orbit and collides with Earth.MeteoritesMeteorites are meteoroids that have impacted the Earth's surface. A meteorite may in fact originate as an asteroid, but meteorites can also come from outside of the solar system. These rocky extraterrestrials can be iron, iron compounds, or stone. Iron meteorites comprise only about 10 percent of all meteorites and contain nickel, which tells scientists they are from outer space.Sponsored Links3D Ground/Earth ScannersGraphical Measuring Results. No Need For A Computer-Get A Quote Nowokm-emirates.com/GroundScannerThe Makeup of Asteroids and MeteoritesScientists once thought asteroids and meteorites consisted of the same materials: stone and iron compounds. However, spectral analyses showed a difference in the reflectance patterns between asteroids and meteorites. It turns out that space weathering, caused by the flow of high-energy ions and small particles, erodes the surface of an asteroid by vaporizing it, and then depositing a layer of film that makes the surface appear dark red. Common meteorites do not have this discoloration.Why Scientists Study AsteroidsScientists study the asteroid belt to gain an understanding of the formation of our solar system and its planets. Asteroids within the asteroid belt between Mars and Jupiter consist of melted minerals. Asteroids from the outer solar system tend to be carbon. The largest asteroid in our solar system is Ceres, which is 580 miles in diameter.The Asteroid MenaceMost asteroids occupy the asteroid belt and orbit the sun in an elliptical orbit. However, some follow different orbits that may bring them into close proximity to Earth. Some scientists believe an asteroid impact caused the extinction of the dinosaurs about 65 millions years ago. Some scientists worry that another asteroid could hit the Earth and wreak havoc on our planet.fference Between an Asteroid and a Meteor?

Answer 2

Answer: Asteroids are a rocks which are a part of asteroid belt in our solar system. Sometimes these asteroids get deflected from their paths and attracted towards earth. When the rocks enter earth's atmosphere, they get burnt due to friction with atmosphere. Some asteroids are large enough and get burnt only partially and reach earth's surface. The rocks which reach the earth's surface are called meteorites.

848 m

Answers

Answer:

35.8 m

Explanation:

An appropriate formula is ...

$V_f^2-V_i^2=2ad$

The initial velocity is 0, and the acceleration due to gravity is 9.8 m/s², so the distance, d, is ...

$d=(26.5^2)/(2\cdot 9.8)\approx 35.8 \quad\text{m/s}$

Ann (mass 50 kg) is standing at the left end of a 15-m-long, 500 kg cart that has frictionless wheels and rolls on a frictionless track. Initially both Ann and the cart are at rest. Suddenly, Ann starts running along the cart at a speed of 5.0m/srelative to the cart.How far will Ann have run relative to the ground when she reaches the right end of the cart?
Express your answer with the appropriate units.

Answers

Answer:

13.5 m

Explanation:

M = Mass of cart = 500 kg

m = Ann's mass = 50 kg

$v_m$ = Velocity of Ann relative to cart = 5 m/s

$v_M$ = Velocity of Cart relative to Ann

As the linear momentum of the system is conserved

$Mv_M+mv_m=0\n\Rightarrow v_M=-(mv_m)/(M)\n\Rightarrow v_M=-(50* 5)/(500)\n\Rightarrow v_M=-0.5\ m/s$

Time taken to reach the right end by Ann

$Time=(Distance)/(Speed)\n\Rightarrow Time=(15)/(5)=3\ s$

Distance the cart will move in the 3 seconds

$Distance=Speed* Time\n\Rightarrow Distance=-0.5* 3=-1.5\ m$

The negative sign indicates opposite direction

Movement of Ann will be the sum of the distances

$15+(-1.5)=13.5\ m$

The net movement of Ann is 13.5 m

What is science?

Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.

A method of learning about the world is science. Science allows people to participate in the creation of new knowledge as well as use that knowledge to further their goals. It is both a process, a product, and an institution.

Thus, The first person to observe the planets through a telescope was Galileo Galilei.

Based on relativity, Albert Einstein created a model of the universe.

A technique to determine the separation between celestial bodies was demonstrated by Henrietta Swan Leavitt.
