A wood block (mass 3.67 kg, density 600 kg/m3) is fitted with lead (density 1.14 * 10^4 kg/m3) so that it floats in water with 0.900 of its volume submerged. Find the lead mass if the lead is fitted to the block’s (a) top and (b) bottom.

A piece of aluminum has density 2700 kg/m 3 and mass 770 g. The aluminum is suspended on a spring scale, and submerged in a container of oil. This oil has a density of 650kg/m 3. What reading will the scale register in grams (g) for the submerged metal?

An aluminum cylinder weighs 1.07 N. When this same cylinder is completely submerged in alcohol, the volume of the displaced alcohol is 3.90 × 10−5 m3. If the cylinder is suspended from a scale while submerged in the alcohol, the scale reading is 0.743 N. What is the specific gravity of the alcohol?  (The density of water is 1.00 × 103 kg/m3)

A cubic block of steel that measures 12. cm on a side is suspended in a saltwater bath by a vertical string. The steel block is completely submerged, but it does not touch the bottom surface. The string applies just enough force to keep the block from sinking further. What force does the string apply to support the block? Density of steel: 8050 kg/m3 Density of saltwater: 1030 kg/m3

Suppose your body has a density of 988 kg/m3. part a)  What fraction of you will be submerged when floating gently in freshwater (with density 1000 kg/m3)? (hint: vsf/vo) part b)   What fraction of you will be submerged when floating gently in salt water (with a density of 1027 kg/m3)?

A block of wood has a mass of 3.71 kg and a density of 515 kg/m3. It is to be loaded with lead (1.13 × 104 kg/m3) so that it will float in water with 0.803 of its volume submerged.

A block of wood has a mass of 3.94 kg and a density of 545 kg/m³. It is to be loaded with lead (1.13 x 104 kg/m³) so that it will float in water with 0.924 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood? (a) Number i (b) Number i Units Units

A scale reads 100 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The mass density of aluminum is 2700 kg/m^3. Be careful, you are given mass density instead of weight density, and we are using SI units.i need answer in problem sigfig

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]

A cube of wood having an edge dimension of 22.1 cm and a density of 651 kg/m³ floats on water. (a) What is the distance from the horizontal top surface of the cube to the water level? cm (b) What mass of lead should be placed on the cube so that the top of the cube will be just level with the water surface? kg
