After running the lab, you select an analysis point with the following properties: atmospheric pressure: 14.7 psia compressor inlet pressure: 0.02 psig compressor exit pressure: 7.24 psig turbine 1 inlet pressure: 7.42 psig turbine 1 exit pressure: 0.41 psig compressor inlet temperature: 20.4°c compressor exit temperature: 145.14°c turbine 1 inlet temperature: 532.9°c turbine 1 exit temperature: 488.48°c fuel flow: 10.26 l/hr engine rpm: 47,222 what is the velocity at the compressor inlet (m/s)?

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

What are the north and south poles of a solenoid change with?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
