Cardiac pacemakers are used by people tomaintain regular heart rhythm when they havea damaged heart. the circuit of a pacemakercan be represented as. the resistance of thewires, r, can be neglected since r < 1 mω.the heart's load resistance, r l , is 1 kω. thefirst switch is activated at t = t 0 , and the secondswitch is activated at t 1 = t 0 + 10 ms. this cycle is repeated every second. find v(t) fort 0 ≤ t ≤ 1. note that it is easiest to consider t 0 = 0 for this calculation. the cycle repeatsby switch 1 returning to position a and switch 2 returning to its open position. 0.6e − 2(t-0.1) v

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.
