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°
The statement is - True.

South Africa's location makes it a key spot for renewable energy in the forms of wind, hydroelectric and solar, as it is on the peninsula of the continent it has access to many of these rich resources. There is also a great deal of industry in South Africa, particularly in the mining of metals, as one of the country's largest exports. This extraction uses huge amounts of energy in the process and most of this equipment used in the extraction pumps toxic gases and chemicals into the atmosphere, if SA uses more renewable energy sources, the levels of pollution will decrease.
