Answer:
None of the above cause thats what i put
Answer:

Explanation:
Hello,
In this problem, the piston-cylinder assembly make us state the energy balance as:

Thus, we must now compute
in terms of Cv as follows:

Now, since heat is given off, its sign is negative, thus, the work is computed as:

This work means that work was done over the system in order to allow the compression.
The suppositions were:
- The change in the internal energy is a function of the temperature.
- Air is an ideal gas.
Best regards.

She is a aerospace engineer.
Explanation:
This is because she works is the aerospace industry, so she must be an aerospace engineer.
Answer:
Tech A is correct
Explanation:
Tech A is right as its V- angle is identified by splitting the No by 720 °. Of the piston at the edge of the piston.
Tech B is incorrect, as the V-Angle will be 720/10 = 72 for the V-10 motor, and he says 60 °.
