Answer:
square metres of plant materials required to support the fox = 3650 m²
Explanation:
From the given information:
the daily caloric requirement of the fox = 800
In a year, we have = 800 kcal × 365 /year = 292,000 kcal/year
Also, only 10% of the energy at a particular trophic level can be passed onto the next.
the net productivity of the plant material = 8000 kcal/m²/yr
So, using 10% of energy at a particular level, the fox only need 80 kcal/m²/yr
The objective is to determine in square meters, how many materials are required to support the fox.
square metres of plant materials required to support the fox = 
= 3650 m²
The scientists need to measure for forces are magnitude and direction.
<h3>What is Force?</h3>
The force is defined as the external effort applied in the form of push or pull to cause the acceleration of a body.
Mathematically it is expressed as the product of mass and acceleration of an object.
therefore standard expression for the force as per Newton's second law is given as,
F = ma
Here,
m is the mass of the body.
a is the magnitude of the acceleration of the body.
Also, the force is a vector quantity that has significance for its magnitude as well as the direction.
So scientific analysis regarding the force needs its magnitude along with the direction of application.
Thus,The scientists need to measure for forces are magnitude and direction.

Answer:
The decision of an ethics review committee about Dr. Franklin's research proposal is:
A:The proposal is approved, as it meets the ethical guidelines defined by the APA.
Explanation:
APA (American Psychological Association) has ethical guidelines for conducting psychological researches. The most relevant one in this case is: "follow informed-consent rules." Dr. Franklin clearly ensures that his students give their consents to participate in the eyewitness testimony study by having each sign a form to agree to participate in the research. I am also sure that the confidentiality and privacy of subjects (students who participate in the research) will be highly protected, in line with another guideline of APA, because these issues have not raised any controversy.
