Condensation trails or contrails, as the phenomenon is known, come mostly from the exhausts of jet-powered aircraft. Jet exhaust (which contains considerable amounts of water vapor) first emerges from the engine hot then is suddenly cooled by the very cold temperatures at the normal flying altitudes of jet aircraft. If the air is near the point of saturation (and cold air cannot carry a lot of humidity), this causes the water vapor to quickly condense and even (if cold enough) freeze into ice crystals. These then form on particulate matter that is also part of the exhaust, forming the long, thin clouds you see behind the aircraft.

Horizontal as opposed to at an angle?
Horizontal is an angle. Angles are reference measurements to another line or plane.
What simple machine is a staircase?
an inclined plane. Take out the steps on a staircase. It looks like a line that goes up at an angle right? That's basically what in inclined plane is. It is a basic function that exerts smaller amounts of energy over a longer period of time. In simpler terms, it makes going upstairs easier than climbing a ladder to the upper floor.
What is meant by the term plane polarised?
Light waves oscillate in the two dimensions perpendicular to it's direction of travel, meaning that they oscillate radially from the centre of the line of travel. Adding a specific filter will cancel out all these oscillations except for in a single plane, whose first axis can be defined as being the direction it is travelling in, and the second being a single line perpendicular to this direction.
What is a simple way to locate the image in a plane mirror?
A simple way to locate to image in a plane mirror without using light rays is to measure the distance of the object itself to the mirror and then draw a dotted line that is equal to the distance of the object-mirror on the other side. Then connect the sides to the end of the line. i had to do this in science today :)
What is the difference between parabola and curve?
A parabola refers to a symmetrical open plane curve that is formed by the intersection of the cone with a plane that is parallel to its side. The curve on the other hand refers to a line that gradually deviates from being straight for some or all of its length.
What will the motion of the plane be if it is flying in a horizontal line?
linear motion
Sketch a line and a plane that do not intersect?
Sketching it is impossible here but think of the ground as the plane and the endless flight of a bee (the bee-line) flying at a constant height as the line which does not intersect it.
What is the white line left behind a plane called?
The white line left behind a plane is called a contrail, short for "condensation trail." It is formed when hot, moist engine exhaust mixes with cold air at high altitudes, causing the water vapor to condense and freeze into ice crystals.
What plane is it that as it flies in the sky it leaves a cloud line?
its a jet stupid. no, wait, its a fly (sarcasticaly) USE YOUR BRAIN
Why you see smoke of high flying airplanes?
That line of smoke is called a vapor trail. You can still see it on low flying planes, but it must be a jet plane.
If two planes are parallel a line in one plane is parallel to a line in the other plane?
if there are two planes, and they are parallel, then i would assume that their lines are parallel too. so yeh yeh a line in one plane is parallel to a line in the other plane...since they are parallel(:ha * * * * * No. Consider yourself in a cuboid room. The wall in front of you and the wall behind you are parallel planes. There is a line on the wall behind you that goes vertically, from the floor to the ceiling. There is a line on the wall in front of you that goes horizontally from left to right. These two lines are on parallel planes, but the lines are NOT parallel. So, (: ha to the person who answered the question previously!
What is the intersection of a plane and a line not on the plane?
point * * * * * or, nothing (if the line is parallel to the plane).
where does a plane intersect in geometry?
A plane intersects a line at a point, and i plane intersects another plane at a line.
When is a line perpendicular to a plane?
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
Can a 14 year old purchase a plane ticket at the airport and get onto the plane without problems?
Different airlines have different polices. Bottom line. Most see a 16 year old competent of flying alone, though you will have to check the airline you are flying with in order to see are you eligible to fly with them.
When does a plane and line intersect at one point?
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
When did Flying Tiger Line end?
Flying Tiger Line ended in 1989.
