Without our atmosphere‚ there would be no life on earth. Two gases make up the bulk of the earth’s atmosphere: nitrogen (78%)‚ and oxygen (21%). Argon‚ carbon dioxide and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth

8th Maths Practice Paper-1 1. An altitude of a triangle is 5/3 of its corresponding base. If the altitude were increased by 4cm and the base decreased by 2cm‚ the area of the triangle would remain the same. Find the base and altitude of the triangle. 2. Some toffees are bought at the rate of 11 for Rs10 and same numbers are bought at the rate of 9 for Rs 10. If the whole lot is sold at one rupee per toffee‚ find the gain or loss percent. 3.

Atmosphere The atmosphere is the body of air which surrounds our planet. Most of our atmosphere is located close to the earth’s surface where it is most dense. The air of our planet is 78% nitrogen and just under 21% oxygen; the small amount remaining is composed of carbon dioxide and other gasses.It is a mixture of gases encircling the Earth and held by the Earth’s gravity. This invisible mixture of nitrogen‚ oxygen‚ argon‚ carbon dioxide‚ and water vapor protects the planet from harmful radiation

P1 – State three purposes of pneumatic supply system for a typical piston engine powered light aircraft‚ and give the functions of the piston engine air compressor and receiver‚ within the system. An aircraft powered by a piston engine usually tends to have a pneumatic air supply system. This allows the function of different systems on the aircraft that are essential to the flight of the aircraft. In a newer system the supply system will provide a vacuum of air for the gyro’s‚ so that the de icing

The Luftwaffe Needs Lessons from the Brits: An Investigation of Hitler’s Defeat at the Battle of Britain By: Jake Pilla Global History II 11-28-07 In 1940‚ German planes flew over Britain in an attempt to take over the country and tear apart the enemy’s alliance. Britain was surprised by this attack‚ but countered by shooting down at least twenty planes of the Luftwaffe‚ the Nazi air force‚ during the initial attack. Hitler sent waves of planes into Britain every day‚ trying to lower

will measure the ranges‚maximum altitudes and air time in order to have a better understanding of the projectile motion.As the practical situation which includes the air resistance and different kinds of errors caused by students’ carelessness is different from the theory‚it is unaviodable that the results are quite different from the theoretic statistics. The horizontal velocity is related to the range‚ while the vertical velocity is related to the maximum altitude. This experiment can help us reinforce

By the time the plane’s sound detector receives the horn’s sound the plane has travelled a distance equal to half its altitude above the ocean. Assuming it takes the sound 2.00 s to reach the plane‚ determine (a) the speed of the plane and (b) its altitude. 4.

culprits behind a weatherman’s forecast of "cloudy" -- sometimes with a chance of drizzle. Stratus clouds are skilled at blocking the sun and can dampen anyone’s enthusiam for sunbathing. Stratus clouds are basically layers of fog that has climbed in altitude either by the virtue of a morning pick-me up or clamboring above a wash of cold air. The base of stratus clouds is generally below 6‚000 feet (2‚000 m). They are quite uniform in appearance and lack any type of ambition to develop into a proper

Pilots need to know the plane’s altitude‚ but why base part of their pay on altitude or oil pressure? In other words‚ are all measures equally important? Should they be weighted equally in determining compensation? • 9. Basing compensation on Global’s performance and on M&R’s performance creates free-rider
