Answer:
T²= 4π²R³/GM
Explanation:
First we know that
Fg= Fc
Because centripetal force must equal gravitational force
So
GMm/R² = Mv²/R
But velocity is 2πR/T
So by substitution we have
GMm/R²= M (2πR/T)/T
We have
T²= 4π²R³/GM as period

Answer:
r = 0.37 m
Explanation:
Use Coulomb's law to solve for r:
F = kq1q2/r^2
---> r^2 = kq1q2/F
= (8.99×10^9)(5.6×10^-4)(-2.1×10^-4)/(-7.7×10^3)
= 0.1373 m^2
or r = 0.37 m
Answer:
Objectivity
Explanation:
In philosophy, objectivity is the concept of truth independent from individual subjectivity (bias caused by one's perception, emotions, or imagination). A proposition is considered to have objective truth when its truth conditions are met without bias caused by a sentient subject. Scientific objectivity refers to the ability to judge without partiality or external influence. Objectivity in the moral framework calls for moral codes to be assessed based on the well-being of the people in the society that follow it. Moral objectivity also calls for moral codes to be compared to one another through a set of universal facts and not through subjectivity.
