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.

What are the key features of a plane mirror diagram?
A plane mirror diagram shows the reflection of an object in a mirror. Key features include the object, its reflection, the mirror surface, and the normal line perpendicular to the mirror. The angles of incidence and reflection are equal, and the image appears to be the same distance behind the mirror as the object is in front.
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 perpendicular to a plane mirror?
The perpendicular to a plane mirror is a line that is at a 90-degree angle to the mirror's surface. It is important for understanding the reflection of light rays off the mirror's surface, as the angle of incidence is equal to the angle of reflection with respect to this perpendicular line.
What is the normal to a plane mirror?
D(power)=1\f ;f=infinity D=0 for plane mirror
Which explains how a plane mirror works?
A plane mirror reflects light by bouncing off the smooth surface of the mirror without distortion. It produces a virtual image that appears to be behind the mirror at the same distance as the object in front of it. The angle of incidence (incoming light) is equal to the angle of reflection (outgoing light) in relation to the normal (perpendicular line) of the mirror surface.
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 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.
What plane will be closer to Paris when they meet if 1 plane leaves ny flying to Paris at 500 miles per hour and 1 plane leaves Paris flying to ny at 450 per hour?
The plane flying from Paris will be closer to Paris. As the planes' noses meet, their tails will be closer to their departure airports.
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 formed by the intersection of a line and a plane if the line does not lie in the plane?
When a line intersects a plane and does not lie in the plane, the intersection forms a single point. This point is where the line crosses the plane. If the line is parallel to the plane, however, there will be no intersection point.
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).
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.
where does a plane intersect in geometry?
A plane intersects a line at a point, and i plane intersects another plane at a line.
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 is a line perpendicular to a plane?
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
