(1
)
C.

(3)
Answer:
a) the roots are unequal.
b) the roots are irrational
c) the roots are non-real

When a plane lands at the local airport, it touches ground and creates an angle between the ground and the belly of the plane. What is a good estimate of the angle measurement?
Answer:
Approximately 3 degrees
Explanation:
As well as taking off, the landing of the plane must be monitored very well, allowing the entire trip to be made safely and efficiently. At landing, it is important for the pilot to estimate which is the best descent profile and what is the best angle to be established between the ground and the belly of the plane. It is preferable that this angle is approximately 3 degrees, which promotes a safe landing, but this value can have small variations.

What special physical property of the upper mantle supports the Theory of Plate Tectonics?
Lithosphere
The lithosphere is the solid, outer part of the Earth, extending to a depth of about 100 kilometers (62 miles). The lithosphere includes both the crust and the brittle upper portion of the mantle. The lithosphere is both the coolest and the most rigid of Earth’s layers.
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. The half-life is 50,000 years. Rock Layer E has undergone radioactive decay ONCE, how many daughter and parent isotopes are present in layer E?
Answer:
Explanation:
By definition, after a radio active decay, a parent isotope will create a daughter isotope.
Layer C is exactly one half-life from Layer E at 50000 years. So half of the original parent isotopes from Layer E would have decayed to form daughter isotopes. As C has 18 radioactive isotopes together, E should have 6 daughter and 6 parent isotopes.
Answer:
Explanation:
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. So the two layers are off by 50,000 years; equal to one half-life.
As Rock Layer E has undergone radioactive decay ONCE, each parent isotope forms one daughter isotope after the decay.
Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. So that represents an equal number of parent and daughter isotopes, i.e. 9 parent and 9 daughter isotopes.
So there are 9 parent and 0 daughter isotopes in layer E.

Imagine you are a city planner. You have the option of providing electricity to your city either through natural gas or through nuclear power. Natural gas is slightly cheaper, but new carbon taxes are about to be implemented in your state. Which do you decide to use? Why?
Answer:
Nuclear power
Explanation:
Even though it may cost a little more, it probably has the less effect on the environment. In times like these with climate change and the earth dying, it is important to do the best we can to reduce it. It has cons tho, nuclear power can be extremely dangerous if it goes wrong... Despite its safety measures, it's still pretty dangerous. Hope it helps!
The natural gas is slightly cheaper but as per taxes in the state, but for city planning more effcient way is to use nuclear power. Thus city panning can be done.
What is nuclear power?Nuclear power is a clean and efficient way of making use of energy resources that can be sued for boiling water that runs the turbines that generate electricity.
The nuclear power is power that is obtained from the fission and the nuclear decay. Even though nuclear power costs bit more but its less effect on the environment.

Answer:
Mountain ranges, earthquake and formation of new lakes occurs.
Explanation:
When two places comes together forming mountain ranges in that area. When two plates move away from one another, earthquakes occurs and magma rises to the surface. The diversion of rivers and the formation of new lakes. Two plates that forms a gap between each other causes the formation of new lakes, diversion of rivers and disturb the weathering patterns. When two plates sliding alongside each other forming faults that leads to earthquakes in that region.

Despite the distance between California and Australia, the value of gold
in the 1800s spurred Gold Rushes on both the North American and
Australian Continents which allowed innovations in mining to spread
between the two countries. This is called-
Select one:
a. Convergence
b.Divergence
c.Transmission
d.Outsourcing
The provocation of Gold Rushes leading to the integration of both the North American and Australian Continents for innovations regarding mining would be called:
A). Convergence
'Convergence' is described as the process of 'merging of distinct technologies or devices into a unified whole.'In the given situation, the coming together of two continents i.e. North American, as well as, Australian continents to work together in the field of mining technology would be called 'convergence.'Since the innovation brought the two continents in unity to work in integration for further development and innovation, it is convergence.Hence, option A is the correct answer.
