A fluid flowing between two plates has a velocity profile that is assumed to be parabolic, where u=4umaxh2(hy−y2)u=4umaxh2(hy−y2). The plates have a width of ww.

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

The necleus of an atom is made up of what subatomic particles?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
