An iron casting containing a number of cavities weighs 6200 N in air and 3970 N in water. What is the total volume of all the cavities in the casting? The density of iron (that is, a sample with no cavities) is 7.87 g/cm3. m3

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 6.22 × 10³ kg/m³. What fraction of the specimen's apparent volume is solid? Number i Units

An​ outdoor, rectangular pool on campus is 4.5 meters​ [m] in width and 7.5 meters​ [m] in length. You may assume the depth of the pool is constant. If the pool is filled with pure​ water, the total pressure probe at the bottom of the pool reads 16.5 ​pound-force per square inch​ [psi]. What is the volume of the water in the pool in units of kiloliters​ [kL]?     Length Force Mass Pressure 1 ft=12 in 1 N=0.225 lbf 1 kg=2.205 lbm 1 atm=101325 Pa 1 in=2.54 cm   1 slug​ = 14.5939 kg 1 atm=14.7 psi 1 m=3.28 ft   Density of water=1000 ​kg/m3 Surface pressure=1 atm

A container has a large cylindrical lower part with a long thin cylindrical neck open at the top. The lower part of the container holds 22.2 m3 of water and the surface area of the bottom of the container is 8.90 m2. The height of the lower part of the container is 2.50 m, and the neck contains a column of water 8.50 m high. The total volume of the column of water in the neck is 0.200 m3. What is the magnitude of the force exerted by the water on the bottom of the container? _____ MN

A hollow spherical iron shell floats almost completely submerged in water. The outer diameter is 66.1 cm, and the density of iron is 7.87 g/cm³. Find the inner diameter. Number Units

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 3.96 × 10³ kg/m³. What fraction of the specimen's apparent volume is solid? Number i Units

A electroA 6.50x109 pg object is placed in a graduated cylinder with 5.560x10-8 dm3 of water. If the object has a density of 7.23 g/mL, what is the final volume (in \muμm3) of the water in the graduated cylinder?

The density of a composite is 1.7 g/cm3. The density of an unknown fluid is 2.2 g/cm3. An object made of the composite will _____ in the unknown fluid.

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A, of 9.8 cm², and the right arm has a cross-sectional area A, of 5.50 cm². Two hundred gra 8 ст of water are then poured into the right arm as shown in Figure b. Water A1 Ag A1 Mercury Densities: Mercury 13.6 g/cm³, Water 1.0 g/cm³ (a) Determine the length of the water column in the right arm of the U-tube. cm (b) What distance h does the mercury rise in the left arm? cm. (c) In figure b, at the level of the dashed line, which side of the u-tube has larger pressure? O Mecure side Water side Same

(1) a. Gold is sold by the troy ounce (31.103 g). What is the volume (in cm3) of 2 troy ounces of pure gold? cm3 b. Mercury is commonly supplied in flasks containing 34.5 kg (about 76 Ib). What is the volume in liters of this much mercury? C. A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density (in g/cm?) of a 200 g rock that displaces 81.0 cm³ of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes' principle.) g/cm3
