Interpretation : The independent variable and the dependent variable are to be identified.
Concept Introduction : The experiment when constructed usually deals with variables or factors that change.
Answer to Problem 63A
Based on the project title, the independent variable is temperature and the dependent variable is the height of the basketball bounce.
Explanation of Solution
The independent variable is the one that can be modified during an experiment. It is also called a manipulated variable.
A dependent variable is measured during an experiment. It is also called a responding variable.
An independent variable keeps changing during an experiment whereas the dependent variable changes according to the independent variable.
According to the definitions, the temperature will be the independent variable while the basketball bouncing height will be the dependent variable.
Interpretation : The factors that should be kept constant during the experiment are to be named.
Concept Introduction : The experiment when constructed usually deals with variables or factors that change.
Answer to Problem 63A
The factors that can be kept constant during the experiment are the size of the basketball, forces carried out throughout the experiment and the height of the basketball traveled.

What kind of relationship is this? How do you know? (see page 276 text) the design of the beaker is a uniform cylinder the volume of liquid increases evenly with its height resulting in a linear relationship. What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the graph to assist you in answering the question. 4. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a best-fit curve through the points and label it "250 mL Florence flask." oke camearrow_forward
