Answer:
External validity.
Explanation:
Whether the results of this study help us to understand the relationship between cell phone use during class lectures and work performance in real-life institutions is a question of <em>external validity</em>. Whether the conclusions of a scientific study can be applied to other institutions and other activities is a matter of external validity. External validity is the generalization of the results of a scientific study to other contexts.
Wave is a disorder that travels through the medium periodically, carrying energy, but not matter. Five parameters determine waves: period, frequency, amplitude, wavelength, and speed. The amount of energy the wave carries is determined by the amplitude. The high amplitude wave possesses a high level of energy, a wave with a small amplitude carries a small amount of energy. In addition, the amplitude does not affect the speed of the waves; both Waves A and B travel at the same speed. The velocity of the wave changes with the characteristics of the media through which they pass.
Right answer is B) the amplitude of the waves.
