Natasha and Reanna observe a large airplane in the troposphere. Which experimental setup below would best determine how changing
wind speeds might affect the airplane’s flight time to its destination? The airplane's flight time is the test variable (independent variable), the wind speed is the outcome variable (dependent variable), and the airplane is the constant.
The airplane's flight time is the outcome variable (dependent variable), the wind speed is the test variable (independent variable), and the airplane is the constant.
The airplane's flight time is the constant, the wind speed is the outcome variable (dependent variable), and the airplane is the test variable (independent variable).
The airplane's flight time is the test variable (independent variable), the airplane is the outcome variable (dependent variable), and the wind speed is the constant.
Explanation: because the airplane's flight time has to be the independent variable for it to affect the dependent variable that is the speed of how fast the airplane is going.
The atomic number is equal to the number of protons in an atom's nucleus. Hydrogen's atomic number is 1 because all hydrogen atoms contain exactly one proton.
