Explanation:
Tech Social Media giant FB is one of those companies. Not long ago the ceo was brought to court to accusations that his company was selling user data. Turns out this is true and they are selling their users private data to companies all over the word. Once the news turned to something else, people focused on something new but the company still continues to sell it's users data the same as before. This is completely unethical as the information belongs to the user and they are not getting anything while the corporation is profiting.

Answer:
The temperature T= 648.07k
Explanation:
T1=input temperature of the first heat engine =1400k
T=output temperature of the first heat engine and input temperature of the second heat engine= unknown
T3=output temperature of the second heat engine=300k
but carnot efficiency of heat engine =![1 - \frac{Tl}{Th} \\](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7BTl%7D%7BTh%7D%20%5C%5C)
where Th =temperature at which the heat enters the engine
Tl is the temperature of the environment
since both engines have the same thermal capacities <em>
</em> therefore ![n_{th} =n_{th1} =n_{th2}\\n_{th }=1-\frac{T1}{T}=1-\frac{T}{T3}\\ \\= 1-\frac{1400}{T}=1-\frac{T}{300}\\](https://tex.z-dn.net/?f=n_%7Bth%7D%20%3Dn_%7Bth1%7D%20%3Dn_%7Bth2%7D%5C%5Cn_%7Bth%20%7D%3D1-%5Cfrac%7BT1%7D%7BT%7D%3D1-%5Cfrac%7BT%7D%7BT3%7D%5C%5C%20%5C%5C%3D%201-%5Cfrac%7B1400%7D%7BT%7D%3D1-%5Cfrac%7BT%7D%7B300%7D%5C%5C)
We have now that
![\frac{-1400}{T}+\frac{T}{300}=0\\](https://tex.z-dn.net/?f=%5Cfrac%7B-1400%7D%7BT%7D%2B%5Cfrac%7BT%7D%7B300%7D%3D0%5C%5C)
multiplying through by T
![-1400 + \frac{T^{2} }{300}=0\\](https://tex.z-dn.net/?f=-1400%20%2B%20%5Cfrac%7BT%5E%7B2%7D%20%7D%7B300%7D%3D0%5C%5C)
multiplying through by 300
-![420000+ T^{2} =0\\T^2 =420000\\\sqrt{T2}=\sqrt{420000} \\T=648.07k](https://tex.z-dn.net/?f=420000%2B%20T%5E%7B2%7D%20%3D0%5C%5CT%5E2%20%3D420000%5C%5C%5Csqrt%7BT2%7D%3D%5Csqrt%7B420000%7D%20%20%5C%5CT%3D648.07k)
The temperature T= 648.07k
