An ac source of period t and maximum voltage v is connected to a single unknown ideal element that is either a resistor, and inductor, or a capacitor. at time t = 0 the voltage is zero and increasing toward a maximum. at time t = t/4 the current in the unknown element is equal to zero, and at time t = t/2 the current is i = -i max, where i max is the current amplitude. what is the unknown element?

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.
