A large cylindrical water tank of diameter od D=3.00 m. The water level is b=10.0 m above the base of the tank and a small hole of 3.00 cm in diamter has formed in the base of the tank and the hole is y=6.00 m above the base of the tank. Both the hole and the top of the tank are open to the air. We can ignore air resistanve and treat the water as an idfeal fluid with density of 1,000 kg/m^3.
a) What is the flow speed of the water when it comes out from the hole?
b) How far the water jet travels horizontally when it reaches ground?
c) If tthe tank is replensihed to remain the same water level, how many cubic meters per second is the tank losing?
Four charges are located in a plane as follows: q1 = -5 uC at (4,0) m; q2 = -3 uC at (4,4) m; q3 = -4 uC at (0,4) m; q4 = -2 uC at (0,0) m. Find the magnitude and direction of the resultant field at (2,2)
