a student tests if the width of a pipe affects pressure of the flow of water. What is the independent variable and the dependent variable?
In this experiment, the independent variable is the width of the pipe. The independent variable is the variable that the researcher purposely changes or manipulates in order to observe its effects on the dependent variable. In this case, the researcher is intentionally varying the width of the pipe to determine how it affects the pressure of the water flow.
The dependent variable is the pressure of the flow of water. The dependent variable is the variable that is being measured or observed in response to changes in the independent variable. In this experiment, the researcher is measuring the pressure of the water flow to determine how it is influenced by the width of the pipe.
To conduct this experiment, the researcher would need to use pipes of different widths and measure the pressure of the flow of water for each width of the pipe. This will allow them to observe any changes or trends in pressure as the width of the pipe is varied.
