3. The (average) density of an object is its mass divided by its volume, M/V. Density can be one of the pieces of information giving clues to what an object is made of. Some information about Jupiter and Earth is shown below: Mass (kg) Radius (m) Earth 5.97 x 1024 6.37 × 106 Jupiter 1.90 × 1027 6.99 × 107 4 a. Using the volume of a sphere V = 3r³ and the data given above, find the average densities of Jupiter and Earth. (2 pts) b. How do the two values you found compare to the density of water (about 1 g/cm³ or 1000kg/m³)? (1 pt) c. Considering your common experience that rock is significantly heavier (more dense) than water and air is significantly lighter, briefly discuss how well the above answers match what you might have expected. You might remember that Earth is being commonly described as "rocky" and Jupiter is often described as a "gas giant." (A couple of sentences is probably enough.) (2 pts)
