Acrate on a motorized cart starts from rest and moves with a constant eastward acceleration ofa= 2.60 m/s^2. a worker assists the cart by pushing on the crate with a force that is eastward andhas magnitude that depends on time. according to f(t) = (5.40 n/s)t. what is the instantaneouspower supplied by this force at t= 4.70 s

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
