Stanley Hall described adolescence as a period so turbulent that it resembled the era in which humans evolved from savages into civilized beings. <em>He was a noted american psychologist and educator that described adolescence as a period characterized by conflict with parents and risky behavior. Hall described adolescence as a cascade of instinctual passions and also coined the term "storm and stress" because he viewed adolescence as a period of inevitable turmoil (from childhood to adulthood). Some of the blame for that period is due to the biological changes of puberty. In the adolescent period the levels of conflict can be easily increased.</em>
Answer: The correct answer is : The critical density for the universe is approximately 10 ^ -26 kg / m ^ 3 or you can also say 10 hydrogen atoms per cubic meter.
Explanation: This value is given by:
critical density = 3H ^ 2/2 Pi G, where H is the Hubble constant and G is Newton's gravitational constant.
Critical density is the average density of matter necessary for the universe to stop its expansion but after an infinite time.
D, i not really sure but, i guess its D
