calculate the density of a solid which weighs 15N in air and 12N in water
Homework Answers
3 N = 1000 kg/m^3 * 9.81 m.s^2 * V
V = 2.06 *10^-4 m^3
mass = m = 15 N/ 9.81 = 1.53 kg
so
density = (1.53/2.06)*10^4 = 7423 kg/m^3
Add Answer to:

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 2.49 × 103 kg/m3. What fraction of the specimen’s apparent volume is solid?
