These factors hinder environmental efforts in Sub-Saharan Africa. inadequate funding, ineffective enforcement, lack of coordinated regional policies, political instability. ... In pre-colonial Africa, government systems did not exist.
Answer:
True
Explanation:
This can be explained in accordance with the General Relativity theory of Einstein's which says that the time dilation depends directly on the intensity of gravitational field (for an observer outside the field).
So, as the intensity of the field increases so does the time dilation.
The black hole has highly intensified gravitational field and as such the time dilation near the boundary of the black hole also increases immensely and stops at the event horizon.
Thus the gravity of a black hole is sufficient enough to slow down a clock as one gets nearer to it.

The climate on the leeward side of a mountain differs from that on the windward side mostly in the amount of rainfall. So the correct option is option "d" in regards to the question that has been given. The climatic condition of the windward side of the mountain is always like an ocean climatic condition while the leeward side has a very dry climate. The air on the windward side rises and gets cold and thus forms precipitation. On the other hand the air comes down on the leeward side and becomes warm and results in a drier climatic condition. </span>
