<h2>Answer:</h2>
All the energy sources are correctly matched with their category.
Explanation:
Renewable energy sources:
These are energy sources which can be replenished as they don't in involves the irreversible phase change.
These resources can never be ended as they can be used again and again.
Wind, geothermal, biomass, bio gas are example of renewable energy sources.
Non renewable energy sources:
These are the energy source which can never be replenished after one time use. They undergo the chemical irreversible change.
These sources are lacking with the passage of time because they can never be reused.
Oil, gas, coal and natural gas are examples.
Nuclear reaction you are literally splitting an atom and in a chemical reaction you are not
Answer:
hello your question is incomplete attached below is the missing part
answer : short period oscillations frequency = 0.063 rad / sec
phugoid oscillations natural frequency (
) = 4.27 rad/sec
Explanation:
first we have to state the general form of the equation
= ![( S^2 + 2\alpha _{p} w_{np} S + w^{2} _{np} ) (S^{2} + 2\alpha _{s} w_{ns}S + w^{2} _{ns} ) = 0](https://tex.z-dn.net/?f=%28%20S%5E2%20%2B%202%5Calpha%20_%7Bp%7D%20w_%7Bnp%7D%20S%20%2B%20w%5E%7B2%7D%20_%7Bnp%7D%20%29%20%28S%5E%7B2%7D%20%2B%202%5Calpha%20_%7Bs%7D%20w_%7Bns%7DS%20%2B%20w%5E%7B2%7D%20_%7Bns%7D%20%20%29%20%3D%200)
where :
![w_{np} = Natural frequency of plugiod oscillation](https://tex.z-dn.net/?f=w_%7Bnp%7D%20%20%3D%20Natural%20frequency%20of%20plugiod%20oscillation)
![\alpha _{p} = damping ratio of plugiod oscilations](https://tex.z-dn.net/?f=%5Calpha%20_%7Bp%7D%20%3D%20damping%20ratio%20of%20plugiod%20%20oscilations)
comparing the general form with the given equation
= 18.2329
![w^{2} _{ns} = 0.003969](https://tex.z-dn.net/?f=w%5E%7B2%7D%20_%7Bns%7D%20%3D%200.003969)
hence the short period oscillation frequency (
) = 0.063 rad/sec
phugoid oscillations natural frequency (
) = 4.27 rad/sec
No cluuuueee :/ sowwwwyyy but good luck
