Apump steadily delivers water through a hose terminated by a nozzle. the exit of the nozzle has a diameter of 25 cm and is located 4 m above the pump inlet pipe, which has a diameter of 5.0 cm. the pressure is equal to 1 bar at both the inlet and the exit, and the temperature is constant at 20degree c. the magnitude of the power input required by the pump is 8.6 kw. and the acceleration of gravity is c = 9.81 m s'. determine the mass flow rate delivered by the pump, in kg/s.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79
