Carbon dioxide is the main culprit.
The dependent variable is: <em>"number of vocabulary words subjects can remember"</em>
<h3>
Which is the dependent variable?</h3>
In an experiment, we basically see how changing one variable affects another variable.
In this case, the experiment is:
<em>" if sleep affects the number of vocabulary words subjects can remember."</em>
Then the hours of sleep would be the independent variable (the one that the scientist can change) and the number of vocabulary words subjects can remember is the dependent variable (that depends on the independent variable).
So the correct answer is:
<em>"number of vocabulary words subjects can remember"</em>

Answer;
= 13.33 m/s²
Solution;
From the second Newton's law of motion;
F= ma
F is the force = 40 N
M is the mass = 3 kg
a is the acceleration;
40 = 3 × a
a = 40/3
= 13.33 m/s²
Hence; the maximum acceleration the bag can withstand before ripping is 13.33 m/s²
