Answer:
A. 29.4 Joules
Explanation:
Given parameters: 
Mass of the book  = 1.5kg 
Height of lift = 2m 
Unknown: 
Potential energy acquired  = ? 
Solution: 
Potential energy is the energy due to the position of a body. 
 Mathematically; 
        Potential energy  = mgh 
m is the mass of the body 
g is the acceleration due to gravity = 9.8m/s² 
h is the height
      Potential energy  = 1.5 x 9.8 x 2 
      Potential energy  = 29.4J

The country with number of hydroelectric projects underway is Pakistan.
<h3>What is hydro electric power?</h3>
Hydroelectric power are energy that are generated using water. 
They covert energy form a flowing water into electrical energy.
Pakistan have made use of hydroelectric power but still have proposal on developing new hydropower. 
Therefore, The country with number of hydroelectric projects underway is Pakistan

When the framers designed the US Constitution they did not give the Federal government much power so power was balanced between States and Central Government. But the Federal government has gained more and more power over time. At the same time, the States were restricted over the years, when the Framers did not imagine doing so.
Both of these situations can be good or bad. For example, making the States respect the Bill of Rights was a good thing when individuals had their basic rights stripped on a State level. So making only the Federal government respect the Bill of Rights did not make much sense.
At the same time, the Federal Government has shown much power that was not designed and showed a few issues over the years, especially with the Executive Branch that had in a few opportunities overstepped its powers.
