An aeroplane heading into a head wind will use up more fuel, than when flying down wind.
An outside agent that affects the speed or occurrence of a reaction is called a catalyst. Catalysts work by providing an alternative reaction pathway with lower activation energy, allowing the reaction to happen more quickly. They are not consumed in the reaction and can be used repeatedly.
Sound does travel slightly faster as air temperature increases and this applies when the sound enters the ear just as it does in any other air. Once the sound has passed the ear drum, air is no longer the medium in which the sound travels so air temperature no longer affects the speed of sound.
I cannot say about "lenght", but distance is a measure of length so length affects distance. Speed is the rate of change of distance (over time) so length affects speed. Mass does not significantly affect speed or distance but, because they are affected by acceleration and acceleration is affected by mass (for a given force), then mass affects them. Also, mass affects space time and the presence or absence of mass changes the lines along which distances are measured and so distances and speed are affected.
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
The drag force exerted by the water on the diver rapidly decelerates the diver's speed after entering the water. This force opposes the motion of the diver and causes a quick decrease in speed. Additionally, the change in medium from air to water also affects the diver's speed.
No. 'Airspeed' is the airplane's speed relative to the air. 'Headwind' and 'tailwind' ... in fact, 'wind' in any direction ... is the speed of the air relative to the ground, which the airplane doesn't feel. So 'wind' affects only the craft's groundspeed, not its airspeed.
speed
Air friction, or drag, acts opposite to the direction of motion, slowing down a falling body as it moves through the air. The greater the surface area of the object or its speed, the more air resistance it experiences, which reduces its speed. This force can eventually reach a point where it equals the force of gravity, causing a terminal velocity, where the object no longer accelerates and falls at a constant speed.
speed
the idle speed air control controls the amount of air going in to the engine so it idles at a certain rpm so it wont stall when you stop at stop signs or so it wont over rev
Most modern fighters can reach speeds of mach 2 or twice the speed of sound but rarely ever do so. Air engagements usually happen at 400 knots or so and acceleration is utilized for positioning more than anything. When needed this type of acceleration needs to happen pretty fast so a lot of power is needed. Then, as a byproduct of power comes speed. But accerating to and maintaining top speed seriously reduces the range of the aircraft because so much fuel is used to attain and maintain that speed.
Of course it affects the air conditioning,,,it also affects the heater. Any time u have a restricted air flow it affects how heater and air conditioning works, for the worse. Engineers have designed the heater/ac system to run on clean air, so therefore your heater/ac systems work faster and better with a clean filter. Not to mention your own physical health by breathing clean air.
