A sea lion (with lungs empty) is put on a scale when it is completely submerged in water. The scale reads the “apparent weight force” of the sea lion in water as 62.01-N. The sea lion has a mass of 210.0-kg. The density of water is 1000 kg/m3. Determine the density of the sea lion. Select one: a. 1000 kg/m3 b. 419 kg/m3 c. 1029 kg/m3 d. 1419 kg/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 2.20 × 103 kg/m3. What fraction of the specimen’s apparent volume is solid?

The curator of a science museum is transporting a chunk of meteorite iron (i.e., a piece of iron that fell from the sky -- see picture at left) from one part of the museum to another. Since the chunk of iron weighs 1240 N and is too big for her to lift by herself, she is using a hand cart (see figure at right). While passing through the marine mammals section of the museum, she accidentally hits a bump and...
