Answer:
Yes, the paths of the two particles cross.
Location of path intersection = ( 1 , 2 , 3)
Explanation:
In order to find the point of intersection, we need to set both locations equal to one another. It should be noted however, that the time for each particle can vary as we are finding the point where the <u>paths</u> meet, not the point where the particles meet themselves.
So, we can name the time of the first particle 
, and the time of the second particle 
.
Setting the locations equal, we get the following equations to solve for and :
Equation 1
Equation 2
Equation 3
Solving these three equations simultaneously we get:
2 seconds
4 seconds
Since, we have an answer for when the trajectories cross, we know for a fact that they indeed do cross.
The point of crossing can be found by using the value of or in the location matrices. Doing this for the first particle we get:
Location of path intersection = ( -1 + 2 , 4 - 2 , -1 + 2(2) )
Location of path intersection = ( 1 , 2 , 3)
A material that resists the flow of electrons is called an insulator.
To solve this problem we will apply the definition of the ideal gas equation, where we will clear the density variable. In turn, the specific volume is the inverse of the density, so once the first term has been completed, we will simply proceed to divide it by 1. According to the definition of 1 atmosphere, this is equivalent in the English system to
The ideal gas equation said us that,
PV = nRT
Here,
P = pressure
V = Volume
R = Gas ideal constant
T = Temperature
n = Amount of substance (at this case the mass)
Then
The amount of substance per volume is the density, then
Replacing with our values,
Finally the specific volume would be
What's the DiDifference Between Asteroids & Meteorites<span>By Karen S. Garvin, eHow Contributor</span>SharePrint this article<span>Asteroids can become meteorites if they fall to Earth.</span>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.<span>Other People Are ReadingThe Characteristics of Comets, Meteors & AsteroidsWhat Kind of Sediment Is a Piece of Meteorite?</span>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.<span>Sponsored Links3D Ground/Earth ScannersGraphical Measuring Results.

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 Menace<span>Most 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.</span>fference Between an Asteroid and a Meteor?
Answer:
Average speed of car in the first trip is 10 km/hr
Explanation:
It is given that first the car drives 6 hours to the east
Then travels 12 km to west in 3 hours
Average speed for the entire trip = 8 km/hr
Total time = 3+6 = 9 hour
So distance traveled in 9 hour = 9×8 = 72 km
As the car travel 12 km in west so distance traveled in east = 72-12 = 60 km
Time by which car traveled in east = 6 hour
So speed 
So average speed of car in the first trip is 10 km/hr
