Here we need to identify the independent and dependent variables in an experiment.

Sadly, we have no information about the experiment, so we need to give a general answer.

In an experiment, we can define 3 types of variables.

Independent variable: Is the thing that we can change as we do the experiment.Dependent variable: Is a variable that responds to the changes in the independent variable, this is the thing we observe/study.Fixed/controlled variables: Are a group of other variables that also affect the dependent variable. Because we want to study the relation between the dependent variable and the independent variable, all of these other things that also affect the dependent variable must remain fixed in the experiment.

Now that you know this you could guess which one is the independent and which one is the dependent.

Just to give an example, suppose that your experiment is "How hot a piece of steel gets in an oven as a function of the time it is inside".

The time, the thing that you control, is the independent variable.

The temperature of the piece of steel, the thing you measure, is the dependent variable.

The controlled variables are things like the type of oven, the temperature at which the oven is, the position of the piece of steel inside the oven, etc.

Answer from: Quest

a and b sometimes have a positive value

For which optical devices does d sometimes have a positive value

Answer from: Quest

Is a vector quantity that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
