Question

after finding that objects of the same mass do not always float or submerge the same way in a tub of liquid, alexis wrote a new hypothesis to test objects that have the same mass. if the surface area of an object increases, then it will float higher in the tub, because the object would need to displace more liquid in order to sink all the way down. what is the dependent variable in this hypothesis? the mass of the object the surface area of the object the amount of water displaced the height at which the object floats

Explanation:

In an experiment, the dependent variable is what is being measured or observed and is affected by the independent variable. Here, the hypothesis is testing how the surface area (independent variable) affects the floating height. The height at which the object floats is what is being measured as it depends on the surface - area change. The mass is kept the same (not a variable in this context), the surface area is the independent variable, and the amount of water displaced is related to buoyancy but not the direct dependent variable in terms of what the hypothesis is phrased about (floating height).

Answer:

the height at which the object floats
