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°
