Its symptoms includes unstable emotions, sense of insecurity, worthlessness, and impulsivity.
This condition can not be cured, but treatments such as therapies, medication (in some cases) could help.
convert 40db to standard gain
AL=10^40/20=100
calculate total voltage gain
=AL×RL/RL+Ri
=83.33
38.41 DB
calculate power
Pi=Vi^2/Ri Po=Vo^2/RL
power gain= Po/Pi
=13.90×10^6
Answer:Counter,

1.921
Explanation:
Given data
![T_{h_i}=200^{\circ}C](https://tex.z-dn.net/?f=T_%7Bh_i%7D%3D200%5E%7B%5Ccirc%7DC)
![T_{h_o}=120^{\circ}C](https://tex.z-dn.net/?f=T_%7Bh_o%7D%3D120%5E%7B%5Ccirc%7DC)
![T_{c_i}=100^{\circ}C](https://tex.z-dn.net/?f=T_%7Bc_i%7D%3D100%5E%7B%5Ccirc%7DC)
![T_{c_o}=125^{\circ}C](https://tex.z-dn.net/?f=T_%7Bc_o%7D%3D125%5E%7B%5Ccirc%7DC)
Since outlet temperature of cold liquid is greater than hot fluid outlet temperature therefore it is counter flow heat exchanger
Equating Heat exchange
![m_hc_{ph}\left [ T_{h_i}-T_{h_o}\right ]=m_cc_{pc}\left [ T_{c_o}-T_{c_i}\right ]](https://tex.z-dn.net/?f=m_hc_%7Bph%7D%5Cleft%20%5B%20T_%7Bh_i%7D-T_%7Bh_o%7D%5Cright%20%5D%3Dm_cc_%7Bpc%7D%5Cleft%20%5B%20T_%7Bc_o%7D-T_%7Bc_i%7D%5Cright%20%5D)
=![\frac{125-100}{200-120}=\frac{25}{80}=C\left ( capacity rate ratio\right )](https://tex.z-dn.net/?f=%5Cfrac%7B125-100%7D%7B200-120%7D%3D%5Cfrac%7B25%7D%7B80%7D%3DC%5Cleft%20%28%20capacity%20rate%20ratio%5Cright%20%29)
we can see that heat capacity of hot fluid is minimum
Also from energy balance

Answer:
<em>Both Tech A and Tech B are correct.</em>
<em>Explanation:</em>
<em>The Hall effect sen sensor are used to control displacements and rotations of various body components of the vehicles, engine vibrations , and the ignition system</em>
<em>The optical-type sensor converts rays of light into electronic signals. It measures the quantity physically of which the translates to a form that is understandable or readable by an instrument. An optical sensor is larger part of a system that integrates light sources, a device for measuring and the optical sensor, which therefore is usually connected to an electrical trigger.</em>
