Answer: Mikhail Gorbachev
Explanation:
In March 1985, Mikhail Gorbachev proposed policies of<em> perestroika </em>(restructuring) and <em>glasnost </em>(openness) in the Soviet Union. These seemed like policies that leaned in the direction of Western ways of economics and politics. <em>Perestroika </em>meant allowing some measure of private enterprise in the Soviet Union. <em>Glasnost </em>meant allowing a bit of freedom in regard to speech and publication. But don't get the idea that Gorbachev was trying to get rid of the Soviet communist system. He actually was trying to prop it up and preserve it, because it was starting to have many problems sustaining itself. But in the end, opening things up a bit with <em>perestroik</em>a and <em>glasnost </em>policies only pushed the USSR further in the direction of shedding the communist model under which it had lived for so long.
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.
the answer is Centripetal Acceleration
Answer: 
Explanation:
The volume of a rectangular prism is given by the multiplication of its three dimensions: length, width and height.
(1)
This also can be seen as the multiplication of the area of one of its faces (length times width, for example) and its height. In fact, this is the case here.
We are given the area of the base of the rectangular prism:
(2)
And the value of its height:
(3)
Hence, the volume of this prism is:
(4)
(5)
Then:
This is the volume of the rectangular prism
