1.
Scientists can test whether it is right or wrong to cut down trees for farmland.
2. True science builds knowledge by following a specific method to collect data.
3. The natural cycles of Earth continue and are unaffected by human impact.
4. Mining underground causes less environmental damage than surface mining.
5. All physical environments on Earth have the same characteristics.
6. Waste in landfills can be reused for other purposes.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
