A solid metal sphere has a radius of 3.39 cm c m and a mass of 1.877 kg k g . What is the density of the metal in g/cm3 g / c m 3 ? (The volume of sphere is V=43πr3 V = 4 3 π r 3 .)
Mass of sphere = 1.877kg = 1.877×1000g = 1877g
Volume of sphere = 4/3 π.r3 = 4/3 × 22/7 × (3.39cm)3
= 163.1878cm3
Density of metal = mass of sphere /volume of sphere
= 1877g/163.1878cm3
= 11.50 g/cm3
= 11.5 g/cm3. (Answer)

A small solid sphere of mass Mo, of radius Ro, and of uniform density Po is placed in a large bowl containing water. It floats and the level of the water in the dish is L. Given the information below, determine the possible effects on the water level L, (R-Rises, F-Falls, U-Unchanged), when that sphere is replaced by a new solid sphere of uniform density. Read it to me he new sphere has mass M = Mn and radius R...

A small solid porcelain sphere, with a mass m and radius r, is placed on the inclined section of the metal track shown below, such that its lowest point is at a height h above the bottom of the loop. The sphere is then released from rest, and it rolls on the track without slipping. In your analysis, use the approximation that the radius r of the sphere is much smaller than both the radius R of the loop and...
