Density times acceleration
WebSo at station 2, the velocity is given by the velocity at 1 plus the gradient times the distance. A similar expression gives the pressure at the exit as shown at the upper right corner of the slide. Newton's second law of motion states that force (F) is equal to mass (m) times acceleration (a). An acceleration is a change in velocity with a ... WebWeight of liquid in tube = density*Area*Height*g. Force of atmosphere = AtmPressure*Area of tube. If you equal the two you get: density*Area*Height*g = AtmPressure*Area. The Areas are the same so they cancel each other out, leaving you with the equation Sal used: density*h*g = AtmPressure. Hope it helped. 2 comments.

WebMass and Weight are two often misused and misunderstood terms in mechanics and fluid mechanics.. The fundamental relation between mass and weight is defined by Newton's Second Law.Newton's Second Law can be expressed as. F = m a (1). where. F = force (N, lb f). m = mass (kg, slugs). a = acceleration (m/s 2, ft/s 2). Mass. Mass is a measure of … WebWhile not negligible, this is not a strong dependence. At 0 °C, the speed of sound is 331 m/s, whereas at 20.0 °C, it is 343 m/s, less than a 4 % increase. Figure 17.6 shows how a bat uses the speed of sound to sense distances. Figure 17.6 A bat uses sound echoes to find its way about and to catch prey.
