Roughly there is 68% of the universe is the total number of energy and Matter is about 27%.
What is Energy?Energy is the name given to the mysterious force that’s causing the rate of expansion of our universe to accelerate over time, rather than to slow down.
That’s contrary to what one might expect from a universe that began in a Big Bang.
Astronomers in the 20th century came to know the universe is expanding. They thought the expansion might continue forever, or eventually if the universe had enough mass and therefore enough self-gravity reverse and cause a Big Crunch.
In early 21st century cosmology, that idea has evolved. The universe is seen as expanding faster today than billions of years ago. Astronomers now sometimes speak of a repulsive force as a possible way to understand it.
What is Matter?Matter can be anything that has mass and volume. For most common objects that we deal with every day, it is fairly simple to demonstrate that they have mass and take up space.
However, the difficulty for people several hundred years ago to demonstrate that air had mass and volume. Air are invisible to the eye, have very small masses compared to equal amounts of solids and liquids, and are quite easy to compress.
Without sensitive equipment, it would have been difficult to convince people that gases are matter.
Now, measure the mass of a small balloon when it is deflated and then blow it up, tie it off, and measure its mass again to detect the additional mass due to the air inside.
Later, scientists were able to compress gases into such a small volume that the gases turned into liquids, which made it clear that gases are matter.

Did the Founding Fathers make the right choice in basing their new government off the beliefs of John Locke rather than Thomas Hobbes?
Answers
Answer:
Yes.
Explanation:
Thomas Hobbes argued that the existence of a government should imply the waiver of some rights that human beings had. This is because for Hobbes, the human being lived in a "natural state" of complete mess, confusion and violence, where all the actions of the human being were to protect his own life. However, this state of chaos demanded the creation of a government, which would control the rights of human beings, thus being able to reduce all the confusion of the natural state.
John Locke, on the other hand, believes that the "natural state" of men is a state of peace and organization, in which case, the creation of a government should not imply the limitation of rights, but the administration of rights, organizing them and guaranteeing the enjoyment of natural rights by people, the most important of which is property.
Although this is not always seen in the current government, we must not tolerate the reduction of rights on account of the government, and we must reinforce the government's responsibility to allow free access to rights and the good quality of life of its citizens. Therefore, we can confirm that the founding fathers chose well, in applying the concepts of Locke and not Hobbes in the creation of the US government.

This, an environment hat has lots of breezes and winds will be required to generate the wind power. Also, the engineer will need to study the environment to use a d carry out necessary analysis and feasibility study to know whether the wind powered will be effective. Therefore, the correct option is environment and society.
