diameter / 2 XI. Prism A prism is a polyhedron with two congruent‚ parallel faces‚ called bases. The other faces are lateral faces. An altitude of a prism is a perpendicular segment that joins the planes of the basses. The height of a prism is the length of an altitude. In a right prism‚ the lateral faces are rectangles and a lateral edge is an altitude. In an oblique prism‚ some or all of the lateral faces are nonrectangular. XII. Lateral Area Lateral area of a prism is the sum of the

of water is stored in a reservoir at a high altitude. A power generation plant‚ consisting of multiple turbines is constructed downstream‚ at a much lower altitude. The reservoir and the power generation plant are connected by large pipelines. When water is released from the reservoir‚ it flows down at a high speed towards the turbine. Naturally‚ the speed at which the water flows down will be directly proportional to the difference between the altitudes of the reservoir and the turbine. As the water

rocket is called a launch vehicle when it is used to launch a satellite or other payload into space. A rocket becomes a missile when the payload is a warhead and it is used as a weapon. At present‚ rockets are the only means capable of achieving the altitude and velocity necessary to put a payload into orbit. Terms to Describe Rocket Power There are a number of terms used to describe the power generated by a rocket. Thrust is the force generated‚ measured in pounds or kilograms. Thrust generated

Explain how each of altitude and oceanic circulation influence climate (10 marks) Both altitude and oceanic circulation have a significant influence on the climate of an area. The effect of altitude is most noticeable in areas such as the Himalayas‚ Alps‚ Rockies and Andes‚ which are much cooler than areas of similar latitude at different altitudes as temperatures decrease steadily with height above sea level.

In this day ’Crew Resource Management’ (CRM) is strongly evident within the aviation industry. Having developed a positive reputation over the years of its application‚ it is highly recognised as an icon for safety practices among many major operators. Airline operators and wider aviation industries adopt CRM‚ on a global scale‚ to attain the desired goal of influencing flight crew members to operate more safely

with increasing altitude. Because the higher you get the more room there is between molecules‚ which means less weight from above. Basically the air gets thinner the higher you get‚ so there is less pressure. 2. Why is the decrease of air pressure with increasing altitude more rapid when the air is cold? Cold air is associated with low pressure. So the inherently low-pressure air loses pressure more rapidly as the altitude increases. Air pressure drops more rapidly with altitude in a column of

ABSTRACT: HELIOS project was a part of NASA’s ERAST programme (Environmental Research Aircraft and Sensor Technology). It was developed by NASA and Californian company AeroVironment Inc. ERAST programme develops pilotless solar powered airplane technology. The HELIOS construction is based upon its predecessors like NASA’s solar plane Pathfinder‚ which was successfully tested a few years prior to HELIOS. Due to its speed HELIOS was able to fly over the same spot for days or weeks‚ therefore‚ in

For example‚ all vehicles traveling at 1‚000 ft altitude would be traveling due north‚ at 1‚010 ft altitude 1 degree east of due north‚ 1‚020 ft altitude 2 degrees east of due north‚ etc. Vehicles would spiral up or down to make their turns.
