An aluminum cylinder of radius 0.10 meter and length 1.0 meter is fully submerged in fresh water and supported by a vertical string attached to one end. The cylinder is motionless and vertically oriented. The density of aluminum is 2700 kg/m3 . a) Find the "net" force exerted by the water on the cylinder. (First consider top, bottom, and curved sides separately.) b) Find the tension in the supporting string. c) If the cylinder were gold instead of aluminum, would...

NEED HLEP PART B!!!!!! 1) You pull a solid copper ball with a density of 8.92 g/cm3and a radius of 1.40 cm upward through a fluid at a constant speed of 7.00 cm/s. The fluid exerts a drag force that is directly proportional to speed, and the proportionality constant is 0.950 kg/s. What is the magnitude of the force (in N) you exert on the ball? (You may ignore the buoyant force.) a) __1.07_____ N b) By what percentage would...
