The mass of a subway car and passengers is 44800 kg. if its acceleration as it leaves

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a. water evaporates, which favors the formation of h2co3. b. pressure decreases, which favors the formation of h2co3. c. the open container warms up, which causes more gas to escape. d. co2is removed, which favors the formation of h2co3.
