1. A block of aluminum that has dimensions 1.16 cm by 3.00 cm by 5.00 cm is suspended by a thread from a spring scale. Density of aluminum is 2702 kg /m3. A beaker full of oil (density 8.50 × 105 g/cm3) rests on a second scale, which reads 460.0 g. The block is then lowered so it is fully submerged in oil without touching the bottom of the beaker. What is the reading on the spring scale supporting the...
