What are the 3 aspects of sound? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. What is the […]
Is there a direct relationship between time in the air and the range?
Is there a direct relationship between time in the air and the range? There is no direct relationship between air time and range because when the initial angle changes, the initial velocity divides into x and y components. as x-velocity increase, the range increases up 5. What is the purpose of a motion graph? Describing […]
Does odometer measure speed or velocity?
Does odometer measure speed or velocity? The odometer gives us only the measure but doesn’t show the direction of velocity. The odometer measures the scalar quantity – the speed of the car. The device may be electronic or mechanical or a combination of the two. How do you calculate distance traveled using odometer? The formula […]
Does lift increase with speed?
Does lift increase with speed? Drag versus speed. method of increasing lift is by increasing velocity if the AOA is held constant just short of the “critical,” or stalling, AOA (assuming no flaps or other high lift devices). Lift and drag also vary directly with the density of the air. Does lift increase with Reynolds […]
What is malleability and example?
What is malleability and example? It is the ability of a solid to bend or be hammered into other shapes without breaking. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Gold and silver are highly malleable. The property is not seen in non-metals. What do you mean by ductility class 8? […]

What types of combustion are there?
What types of combustion are there? Here’s a closer look at five types of combustion: Complete Combustion. Complete combustion requires a combination of fuel and oxygen. Incomplete Combustion. Incomplete combustion occurs when there is not enough oxygen for the fuel to fully react. Rapid Combustion. Spontaneous Combustion. Explosive Combustion. What three things are needed for […]
Which signal analog or digital is a more reliable way to transmit information?
Which signal analog or digital is a more reliable way to transmit information? Because of these things, digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information than analog signals. Digital signals are patterns generated by sampling a stream of continuous data at regular intervals. What is a disadvantage […]
What color is closest to the central maximum?
What color is closest to the central maximum? Violet and blue will be seen closer to the central maximum — then green and yellow and orange and finally red, farthest from the white central maximum. a) is a diffraction source. Why is diffraction grating better than a prism? However, a diffraction grating is less sensitive […]
What is the angle of incidence in aviation?
What is the angle of incidence in aviation? On fixed-wing aircraft, the angle of incidence (sometimes referred to as the mounting angle or setting angle) is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum […]
