That the field studys the social context in relationships, society, family, school, etc. The way we form relationships, how society affects the relationships we decide to form, how much society influences our decisions, jobs, education( more than we can imagine.)
I believe the most aggravating issue is the police bruality. The fact that the men who are suppose to be heroes, save lives through enforcing the laws, and give protection to the citizens, are instead acting as criminals themselves killing and creating a sense of danger is inexcusable and a solution needs to be made .
Answer:
a) v² = G M R³, b) T = 2π /
, c) 
Explanation:
a) The kinetic energy is
K = ½ m v²
to find the velocity let's use Newton's second law
F = m a
acceleration is centripetal
a = v² / R
force is the universal force of attraction
F = G m M / r²
we substitute
G m M R² = m v² R
v² = G M R³
the kinetic energy is
K = ½ m G M R³
b) angular and linear velocity are related
v = w R
w = v / R
w =
w =
the angular velocity is related to the period
w = 2π / T
T = 2π / w
we substitute
T = 2π /
c) the angular moeomto is
L = m v r
L = m RA G M R³ R
L =
