Answer:
Explanation:
Given that the airplane starts from the rest (this is initial velocity equals to zero) and accelerates at a constant rate, position can be described like this: 
where x is the position, t is the time a is the acceleration and 
is initial velocity. In this way acceleration can be found. 
.
Now we are able to found velocity at any time with the formula: 
The IRB at the university will decide whether her study meets ethical guidelines before it is initiated. The importance of these codes of conduct is to safeguard research participants, the status of psychology and the researchers or psychologists themselves. Moral issues hardly yield a simple, unequivocal, right or wrong answer. It is consequently often a matter of judgment whether the research is justified or not. For instance, it might be that a study roots psychological or physical uneasiness to participants, maybe they agonize pain or maybe even come to solemn harm.
Answer:
c) It has a greater frequency than red light but a smaller frequency than blue light.
Explanation:
According to the relation:
c = frequency × Wavelength
The higher the frequency, the lower the value of wavelength
The order of wavelength is:
Violet < Indigo < Blue < Green < Yellow < Orange < Red
Stated above, frequency is inversely proportional to the wavelength. Thus, the order of wavelength is:
Violet > Indigo > Blue > Green > Yellow > Orange > Red
Thus,
<u>Green light has lower frequency than blue light and higher than red light.</u>
