What are the 3 aspects of sound?
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 […]

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.

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 […]
