F1 = G*m²/D²
<span>F = 2*F1*cos30° = 2*G*50²*cos30°/0.3² = 3.21E-6 </span>
<span>a = F/m = 3.21E-6/50 = 6.42E-8
Hope this helped!

Identity vs. Role confusion is the 5th stage of Erik Erikson's theory of psychosocial development.
During this stage, adolescents try to explore their independence. They begin to get interested in social interaction and relationships. This is also the time they begin to feel confused and insecure about themselves trying to figure out how to fit in the group. This is the reason why they engage themselves in different roles and activities.
Answer
The Value of r = 0.127
Explanation:
The mathematical representation of the two resistors connected in series is
And from Ohm law
The mathematical representation of the two resistors connected in parallel is
From the question 
=> 
Dividing equation 2 with equation 1
=> 
We are told that 
From equation 3
Using the quadratic formula
a = 1 b = -8 c =1
Now r = 0.127 because it is the least value among the obtained values
Answer:
<u>Informed Consent- The study didn't conform this ethical standard.</u>
<u>Debriefing- The study conforms this ethical standard.</u>
<u>Confidentiality- The study conforms this ethical standard.</u>
<u>Protection from harm- The study conforms this ethical standard.</u>
Explanation:
<u>Informed consent</u> is described as a procedure whereby researchers tend to provide details about specific research they are going to conduct, the risk & benefits involved in the study, different alternatives involved in the procedure, etc.
<u>Debriefing </u>is described as a process that is being conducted in any of the different psychological research encompassing human participants after specific research is completed. The researcher tends to describe the details of the research to the participants.
<u>Confidentiality</u> is described as one of the different code of ethics followed by health workers or psychologists. While practicing confidentiality, a psychologist tends to promise his or her participants that he or she will keep everything a secret whatever is being discussed or shared between both of them.
<u>Protection from harm</u> determines that the psychologists conducting research follows the ethics in which he or she has to protect all the participants from any kind of harm.
Answer:
a = 4.72 m/s²
Explanation:
given,
mass of the box (m)= 6 Kg
angle of inclination (θ) = 39°
coefficient of kinetic friction (μ) = 0.19
magnitude of acceleration = ?
box is sliding downward so,
F - f = m a
f is the friction force
m g sinθ - μ N = ma
m g sinθ - μ m g cos θ = ma
a = g sinθ - μ g cos θ
a = 9.8 x sin 39° - 0.19 x 9.8 x cos 39°
a = 4.72 m/s²
the magnitude of acceleration of the box down the slope is a = 4.72 m/s²
