Alarge, cylindrical water tank with diameter 3.60 m is on a platform 2.00 m above the ground. the vertical tank is open to the air and the depth of the water in the tank is 2.00 m. there is a hole with diameter 0.520 cm in the side of the tank just above the bottom of the tank. the hole is plugged with a cork. you remove the cork and collect in a bucket the water that flows out the hole. part a when 1.00 gal of water flows out of the tank, what is the change in the height of the water in the tank?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
