A spring stretches 3.9 cm when a 10-g object is hung from it. The object is replaced with a block of mass 25 g that oscillates in simple harmonic motion. Calculate the period of motion. 24. When four people with a combined mass of 320 kg sit down in a car, they find that the car drops 0.80 cm lower on its springs.
• Compares the mass of an object to its volume. • Is the mass of a substance divided by its volume. Density expression Density = mass = g or g = g/cm3 volume mL cm3 Note: 1 mL = 1 cm3 Density. 3 Densities of Common Substances. 4 Osmium is a very dense metal. What is its density in g/cm3 if ...
