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:
1.78 rad/s
1.70344 rad/s
Explanation:
v = Velocity = 0.8 m/s
m = Mass of person = 60 kg
= Distance between center of mass of person and pole = 0.45 m
= New distance between center of mass of person and pole = 0.46 m
I = Moment of inertia
Angular speed is given by
The angular speed is 1.78 rad/s
In this system the angular momentum is conserved
The new angular speed is 1.70344 rad/s
Answer:
When Jill is pushing a box across a floor, it represents the upward motion and it is natural force is applied.
So it is represented as FN and normal force takes place in considering the force perpendicular to the floor.
It seems to support that forced applied on an object when the object is in contact with other.

Answer:
For sound waves to travel, there is a requirement of medium and density of the medium is considered to be one of the factors on which the speed of sound depends. When the medium is dense, the molecules in the medium are closely packed which means that the sound travels faster.
Explanation:
