1.1 An engineer claims the following about the digital format: “ In a digital system, logic 0 and logic 1 are represented by two voltage levels. Since there is a significant voltage difference between the two levels, noise will not affect the logic value, and thus digitized information is immune to noise.” Is the statement correct? Explain.

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
