Answer:
It's important that the U.S. Constitution defines citizenship because it guarantees it to people who are born within the United States.
Explanation:
It"subjects to the jurisdiction thereof".
Answer:
11.23%
Explanation:
Lets take
Speed of man in still water =u= 1.73 m/s
Speed of flow of water = v=0.52 m/s
When swims in downward direction then speed of man = u + v
When swims in upward direction then speed of man = u - v
Lets time taken by man when he swims in downward direction is
and when he swims in downward direction is
Lets distance is d and it will be remain constant in both the case




Time taken in still water
2 d= t x 1.73
t=1.15 x d sec


total time in current = 0.82 +0.44 d=1.26 d sec
So the percentage time

Percentage time =11.32%
So it will take 11.32% more time as compare to still current.
KE = 1/2mv^2
1/2(10.5)(9)^2
1/2(10.5)(81) = 425.25 J
