a cylinder , 10.0 m long and 5.00 m in radius, is completely submerged in water. what is the buoyant force on the cylinder

A plastic cube (density 973 kg/m3) has side length 1.90 cm. You drop the cube into a jar of maple syrup (density 1131 kg/m³) -you don't know why- and observe that it floats in the syrup . What percentage of the plastic cube is submerged? [Answer as a percentage with 3 sig digits, but do not enter '%' with your answer]

Vb = D A D Vmax = m³ c) What is the depth D below the waterline? W max = b) What is the volume of water displaced when the barge is empty? This will be in terms of D. m h Water. line m³ 1) A flat bottomed barge in the water has a base with area A 4000 m². The height, h, of the barge is 2 m. and the distance D is the depth of the barge below the i water line. The mass of the barge when empty is m, = 1,000,000 kg. N a) What is the weight of the empty barge? 9,800,000 mg = 1,000,000 (9.8) W₁ = The theoretical maximum mass of the barge, including its load, will be when the top of the barge is at the water level. d) What is the maximum volume of water displaced, and the mass of this much water? e) What is the theoretical maximum weight of the barge? N Illmax = - 16 hour!! (3) kg 525555, 004 Hae ad 11.

Question 13 An object of mass 4.27 kg is connected to the lower end of a string. When the object is underwater and the tension in the string is 7.09 N. What is the smallest density of a liquid in which the rock will float? (PUHQ1326) a) O1000.00 kg/m3 b) O1810.00 kg/m3 c) O1200.00 kg/m³ d) 03680.00 kg/m³

help A concrete block with a density of 6550 will sink in water, but a rope suspends it underwater underwater (that is, its completely underwater, not touching the bottom of the lake, and isn't moving. It measures 63 cm x 20 cm x 15 cm, and has a density of 6550 kg/m3. The density of water is 1000 kg/m3 Find the tension in the rope. Hint: Buoyancy problem - similar to the last problem, but add a rope pulling up.
