The kinetic energy of the air travelling at 20m/s, which passes through

the circular area in 1 second is 5.4 x 10⁵ J.

What is kinetic energy?

The kinetic energy of an object is associated with its motion. It can be related to the mass and velocity as

K.E = 1/2 mv²

Given the wind is blowing directly towards the wind turbine at a speed of 20 m/s. At this wind speed, 7500 kg of air passes every second through the circular area swept out by the blades.

Substitute the values, we have

K.E = 1/2 x 7500 x (20)²

K.E = 15 x 10⁵ J

Hence, the kinetic energy of the air travelling at 20m/s, which passes through the circular area is  15 x 10⁵  J.

<u><em>[NOTE: THIS IS AN INCOMPLETE QUESTION. THE CMPLETE QUESTION IS: the wind is blowing directly towards the wind turbine at a speed of 12 m/s. at this wind speed, 7500 kg of air passes every second through the circular area swept out by the blades. Calculate the kinetic energy of the air travelling at 12m/s, which passes through the circular area in 1 second.]</em></u>

Why might the supremacy clause cause conflict? Provide an example
likoan [24]

Answer:

The Supremacy Clause provides for the Constitution and the Laws created by the United States to be the “Law of the Land”, which means that the federal government holds power over any laws created at the state level. The tenth Amendment is meant for states to create laws that are not currently reserved by the federal government.

This means that states can make their own laws that the Federal Government currently does not have the power to enforce. Whenever a state proposes a law that conflicts with a federal law, the federal government will always win. For example, if a state wanted to reintroduce slavery, the Supremacy Clause and the 13th Amendment would supersede the state’s request. A state however, can make their own traffic, and criminals law, etc.

The Federal government is responsible for making laws regarding the military, money, taxes, international relations, etc. The states are responsible for state level taxes, transportation, capital punishment, family law, etc.
