1)A hollow sphere is held below the surface of a lake by a cord anchored to the bottom of the lake. The sphere has a volume of 1 cubic meter and the tension in the cord is 5N.(a) Calculate the buoyant force exerted by the water on the sphere.(b) What is the mass of the sphere? (c) The cord breaks and thesphere risesto the surface. When the sphere comes to rest, what fraction of its volume will be submerged?

A flower falls to the bottom of a lake. Once it is on the bottom, it will release pollen (a little sphere) which begins to float towards the surface The drag force on a sphere in fluid is F​drag​​=6πrηv, where r=100 μm is the radius of the pollen, η=10^−3 Ns/m^2 is the viscosity of water and v is the velocity of the pollen. The density of pollen is p​​=300kg/m​^3​​ and the density of water is ρ​w​​=1000kg/m​3​​. The pollen floats due...

A man of mass m=74.0 kg is holding his breath and floating, at rest, on the surface of a lake. While holding his breath, his density is p=994.0 kg.m^3. He exhales, which increases his density to 1030.0 kg/m^3 and so he begins to sink. The density of water is 1000.0 kg/m^3. a) when the man is floating at the surface of lake, what percent of his body's volume is above water? b) once the man exhales, what is the buoyancy...

A metallic cubic block of length s=3.25cm is held at rest below water (Pw=1.00x10^3kg/m^3) by a hand that applies a force of 2.74N vertically up. The upper face of the block is 3.70 cm below the surface of the water, which in turn is exposed to the atmosphere. a) What is the density of the block? b) Determine the absolute pressure at the bottom face of the block immediately after the hand is removed. Give the result in kPa. Draw...

A diver is located 63 m below the surface of the ocean (the density of seawater is 1025 kg/m^3). To raise a treasure chest that she discovered, the diver inflates a plastic, spherical buoy with her compressed air tanks. The radius of the inflated buoy is 0.41 m. If the treasure has a mass of 215 kg, what is the acceleration of the buoy and the treasure chest when they are tethered together and released? The chest is 22 cm...

1. Three objects have the same volume, one spherical, one rectangular, and the other cylindrical. If you put these 3 objects under water, how do their buoyant upward forces compare? A. According to Archimedes’ Principle, they are all subject to the same amount of buoyant forces because they have the same volume B. The cylindrical object gets the most buoyant force because it has a longer shape C. The rectangular object gets the most buoyant force because of its flat...
