Solve using proportionalities by stating the appropriate proportionality law and finding the proportionality constant:

• If a small whale 3.8 meters long has a mass of 408.24 kg, then what should be the mass of a geometrically similar whale 8.2 meters long?
• If the first whale is losing thermal energy at the rate of 518.4 watts, then under identical conditions at what rate would we expect the second whale to be losing energy?
