Answer:i don't know sorry good luck tho
Explanation: i have not learned it yet
whether or whether the conclusions apply to people whose location and circumstances differ from those of the study's participants need to asked to ensure both the external and internal validity of your results
<h3>How can external validity be guaranteed?</h3>
Broad inclusion criteria that produce a study group that more closely mimics real-life patients and, in the case of clinical trials, selecting interventions that are practical to implement can both boost external validity.
<h3>What steps would you take to make sure your study is reliable and valid?</h3>
The development of a solid study design, the selection of suitable methodologies and samples, and the meticulous and consistent execution of the research are all necessary for the reliability and validity of your findings.

Answer:
730.4 m
Explanation:
The sound waves travels with a uniform motion (=constant velocity), therefore we can calculate the distance it travels using the formula:
where
d is the distance
v is the speed of the sound wave
t is the time taken
In this problem we have:
v = 332 m/s is the speed of sound in air
t = 2.2 s is the time elapsed
Therefore, the distance between the tower and the person is

You need to check the temperature of food being stored in a temperature-controlled environment every four hours. The process of changing a space's temperature is called temperature control.
Cooking food alone may not be enough to avoid food poisoning, though, if the bacteria in food are allowed to grow to large numbers. When the temperature is between 5°C and 63°C, bacteria can grow. The risk zone is the range between 5°C and 63°C.
Temperature control is a process where the passage of heat energy into or out of a space or substance is adjusted to achieve the desired temperature. This process involves measuring or otherwise detecting changes in the temperature of the space (and all of the objects contained therein) or of the substance.
