Scientist wants to see which type of liquid will make plants grow taller. The scientist gives three plants an equal amount of water, sunlight, soil, and amount of growing space. The scientist gives one plant soda, one plant milk, and one plant water. After a month the height of each plant is measured. What is the hypothesis, independent variable, dependent variable, constant variables, and control?

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?
