Answer:
Content validity
Explanation:
Your friend, Tania, is asking your advice on her new study design. She is conducting a study on whether milk chocolate consumption prior to a memory task will improve recall performance as compared to consuming white chocolate. She decides to include three participants in each group. You tell her that she should likely have more participants or she will lack <u>content</u> validity. Content validity has to do with whether your research subjects or respondents are representative of all aspect of your research construct. Increasing the sample size or the number of replicates per treatment increases the construct validity by increasing the degree of freedom and reducing experimental error. Increasing the sample size will make the study a more representation of the entire study population.
The term that is described above is irregular. This word explains things that are not exactly on point, not in position, this is used when things are not organized. The term regular on the other hand is completely opposite for they are use in defining things that are planned and more organized, things that are point and are in the exact line.
Answer:
There is no short answer.
Explanation:
Underdamped motion can be described as the type of motion where if the system is affected by a force, the oscillations of the movement slowly decreases until it reaches to an equilibrium. An example the underdamped motion can be a door that automatically closes with the help of a spring. If underdamped, the door swings back and forth until it stops.
Critically damped motion can be described as where the system does not oscillate and returns to its equilibrium as quickly as possible. Going with the door example, if the system is critically damped, the door closes as soon as it is released and does not move anymore.
Overdamped motion can be described as where the system again does not oscillate and returns to its equilibrium point but does so more slowly than the critically damped system. This time the door closes without swinging but its motion is much slower compared to the previous example.
Resonance can be described as a force or a wave of any kind overlapping with another with the same frequency and therefore amplifies the original amplitude of the force or wave. An example to this concept can be a swing, when pushed at the same frequency, its motion becomes bigger.

Queen Hatshepsut sent ships for myrrh in Punt, and extended Egyptian trade into modern-day Somalia and the Mediterranean.
True. All things are made of atoms :)
