The speed increases, because as the angle increases (the wing slants up more steeply), the air has to go farther to get over the wing.
Answer:
A. Adjusts how far down the piston travels
Explanation:
This type of engine changes the possition of the piston in order to modify the compression chamber volume and therefore the compression ratio of the engine. The volume of the chamber is proportional to the run of the piston (how far down the piston travels)
This engine is used to achive the optimal compression rate in each individual stage.
More energy is used in creating a louder sound from the mouth.
<h3>What must you do to produce a louder sound?</h3>
We use more energy in order to produce a louder sound because energy is the thing that helps in the formation of loud sound. Loudness is dependent on the energy that creates loud sound in the mouth. More energy we apply, more loud sound will produce. Energy is the main factor which gives us a loud sound in each and every instruments. Without, we can't imagine loud sound.
So we can conclude that more energy is used in creating a louder sound from the mouth.
