The device delivers a current of 15.0 A for 30 seconds, resulting in a total charge of 450 C . This charge corresponds to approximately 2.81 × 1 0 21 electrons flowing through the device. Thus, around 2.81 × 1 0 21 electrons pass through it in this time frame.

In psychology experiments, defining independent and dependent variables is crucial for understanding the relationship between different aspects being studied. In this particular experiment, you're testing attention and perception by having participants watch videos with varying background interactions. Here, the dependent variable is the response of the viewer, as it's the main focus of observation and remains unchanged except for how it reacts to the independent variable. On the other hand, the independent variable is the background content of the video, which you intentionally alter to see its impact on viewers' perception.
Defining these variables clearly helps establish a cause-and-effect relationship in research. Why is this important?
Clarity and Understanding: Clearly defining the variables makes it easier for others to study the experiment and understand what exactly is being measured.
Establishing Causality: It allows researchers to better understand if and how changes in the independent variable create changes in the dependent variable.
Reliability: Clearly defined variables ensure the results are reliable. Without this clarity, the findings might be questionable because it's unclear what influenced the outcomes.
Replication: Other researchers need to be able to replicate your study to validate the results. Replicability is only possible when all aspects of the study, including variables, are clearly detailed. This is particularly important in psychology, where confirming findings in different settings and times enhances credibility.
By focusing on these aspects, researchers can conduct thorough and reliable studies that contribute meaningfully to psychological science.
