The ability to generalize a study's results to different circumstances is known as external validity that suffers from 7 types of threats.
<h3>What are the threats to External Validity?</h3>
There are 7 major threats to external validity.
- The first threat is sampling bias, in which a sample is not representative of the population.
- The second threat is history, where an unrelated incident can affect the results.
- The third threat is observer bias, in which the traits or actions of the experimenter unintentionally affect the results, resulting in bias and other demand features.
- The fourth threat is the Hawthorne effect, which describes the propensity for individuals to alter their behaviour merely because they are aware that they are being observed.
- The fifth threat is the Testing Effect, in which the results are impacted by whether a test is administered before or after another.
- The sixth threat is the aptitude-treatment, which involves the interaction of individual and group factors to affect the dependent variable.
- The environment, time of day, location, researcher traits, and other variables that restrict the generalizability of the results are included in the seventh threat.

We are looking for the value of the second integer, so let's mark it as X.
Then three consecutive integers are : (x-1) , x , (x+1)
The sum of the first and the third integers (X-1) + (X+1)
Five less than three times the second integer 3X - 5
Now we can write an equation and solve it for X
(X-1)+(X+1)= 3X - 5 simplifying left part
2X = 3X -5 subtract 2X from both sides
0 = X-5
X=5
SO THREE CONSECUTIVE INTEGERS ARE 4, 5, 6
During a research work, an effective and efficient way to follow the scientific method includes:
Make observations.
Ask questions.
Construct a hypothesis.
Test the hypothesis with an investigation.
Analyze the data.
Explain the result.
Communicate the result.
The scientific method is the variety of techniques that scientists use to observe, examine, investigate, and study the natural world and explain it based on evidence, theories, evidence, hypotheses, or factual information that scientists derive from their research work.
It can be defined as the scientific method usually involves combining traditional scientific processes with critical thinking, scientific knowledge, and reasoning to generate new ideas. Please note that if your hypothes is true, it should be shared with the community. However, if your hypothesis is wrong, you should build another hypothesis and repeat the process.

Answer:
100N
Explanation:
m= 5kg
a= 20 m/s^2
F= ma = 5kg x 20 m/s^2 = 100kg m/s^2 = 100N
