1. (a) Define density and state its units in the SI system of units. (b) What does a negative zero reading on a Vemier caliper mean? (7pts) 2. (a) Calculate the average value for the following experimentally determined numbers: 2.78, 2.53, 2.36, 2.81, and 2.37. (b) If the standard value is 2.66, what is the percent error in your measurement? All numbers have units of cm. (8pts) 3. A rock is placed in a graduated cylinder containing water, and the...
A rock is suspended from a string in air. The tension in the string is 2.94N. The rock then is submerged in a liquid, and the tension in the string drops to 2.06N. If the density of the rock is 2.55 g/cm3 what is the density of the liquid?
Q1: Substance A has a density of 3 g/cm3 and substance B has a density of 4 g//cm3. In order to obtain equal masses of these two substances, what must be the ratio of the volume of A to the volume of B?
6. Substance A has a density of 3 g/cm3 and substance B has a density of 4 g/cm3. In order to obtain equal masses of these two substances, what must be the ratio of the volume of A to the volume of B?
An object has a mass of 100 kg and a density of 10 g/cm3. What is the volume of the object in cm3? (Hint: Watch Session 13/Lecture/Video Lessons on Matter/Density)
A rock with a mass of 489 g in air is found to have an apparent mass of 308 g when submerged in water. (a) What mass (in g) of water is displaced? g (b) What is the volume (in cm3) of the rock? cm3 (c) What is its average density (in g/cm3)? g/cm3 Is this consistent with the value for granite? Yes O O No
