6. Two students, John and Jay are given a small cylinder of aluminium of known mass and asked to determine its density. (The 'accepted' density of aluminium is 2.702 g/cmº.) Since density is mass/volume, the students need to calculate the volume of the cylinder. The height and diameter of the cylinder need to be measured in order to calculate its volume John is told to use a simple plastic ruler and to make four independent measurements for each dimension. Jay is told to use a precision measuring tool called a micrometer. John – plastic ruler 2.2 g/cm 2.3 g/cm 2.7 g/cm 2.4 g/cm³ Jay – micrometer 2.703 g/cm³ 2.701 g/cm³ 2.705 g/cm³ 5.811 g/cm³

In the diagram below there is a thick-walled cylindrical tube. Its height is H = 5.0 m, its inner radius is R1 = 1.0 m, its outer radius is R2 = 3.0 m and its mass is M = 10.0 kg. The volume density is proportional to the square of the height h measured from the top of the cylinder: p x h?. R2 a) Proof that the proportionality constant k (p = kh?) is k = , ms 100m b) Determine the position of the center of mass of this object. c) Determine I, the moment of inertia of the cylindrical tube around the axle going through the center of the top (as shown on diagram). You can use lying =mr? (the rotational inertia of a ring of radius r and mass m rotating around an axis parallel to it, through its center).

You want to calculate the volume of air that occupies a standard volleyball. You measure the diameter of the balloon with a ruler graduated to the millimeter. The measurement is rather difficult to take, but you trust that the correct measurement is somewhere between 20.8 cm and 20.9 cm. Calculate the volume of air inside the balloon as well as the uncertainty of this value and give the answer in cm^3.
Please help. This problem involves finding the radius and volume of a platinum atom using its density. Thank you.
The erythrocyte sedimentation rate (heaviness) test is often used for a blood sample as a diagnosis of the body's immune disorders and some other diseases. Assuming that the red blood cells are about a sphere of diameter ( 5 um ) and density ( g / ml 1.125 ) and the density and viscosity of the plasma in which the red blood cells are settled (Pa.s), (1025 kg / m3 10-3 x 1.5) respectively The acceleration m / s 9.81 Calculate the rate of sedimentation (settling speed) of red blood cells.
