Debbie is studying the scientific method in her physical science class. She is working on a science fair project and needs to determine the variables that she will use. Which statement could help Debbie understand the difference between a test variable (independent variable) and an outcome variable (dependent variable)? The outcome variable (dependent variable) is the control and test variable (independent variable) is the result.

The test variable (independent variable) is the result of the changes the researcher makes to the outcome variable (dependent variable). O The test variable (independent variable) is the control and the outcome variable

(dependent variable) provides the results, which are measured to gather data.

The outcome variable (dependent variable) is the result of the changes the researcher makes to the test variable (independent variable).

terd muffin is the correct answer

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic

pretty sure it's false
