Answer:
answer 15 correct option is b. 73.7°
answer 16 correct option is с. 47°
Explanation:
we know that on 4th july Northen hemisphere have summer and Washington, D.C also in Northen hemisphere
and sun present at 23.5° latitude
so latitude of sun is calculate as given figure below
= 90° - ( 39° - 23.5° )
= 74.5°
so correct option is b.73.7
this difference if because we take latitude 23.5° that is approx on 24 july
but july 4 latitude will be some low
and
we know during summer declination angle is + 23.5 in N.H.
and during winder declination angle is - 23.5 in N.H.
and at spring and autumn sun is at equator
the declination angle change is
declination angle change = 27.5 + 27.5 = 47°

Answer:
the Appalachian Mountain
Explanation:
The European settlers in what is now the United States quickly started to push the natives of their lands and create their colonies. As they were doing so, they started to establish towns and villages, create their own plantations, implement their rules and laws. But this was all happening along the eastern coastline and in close proximity to it. The reason for this was that they had a very big natural barrier in front of them that didn't allowed them to spread out toward the west. This natural barrier were the Appalachian Mountains. The Appalachians are a mountain range that separates almost all of the eastern coastline area from the interior of the country. These mountains are relatively high, had very dense impenetrable forests, and were very dangerous for crossing, so the Europeans avoided them until they developed better means of travel and transportation.
