Answer:
The entity relationship (ER) data model has existed for over 35 years. It is well suited to data modelling for use with databases because it is fairly abstract and is easy to discuss and explain. ER models are readily translated to relations. ER models, also called an ER schema, are represented by ER diagrams.

Answer:
Stress corrosion cracking
Explanation:
This occurs when susceptible materials subjected to an environment that causes cracking effect by the production of folds and tensile stress. This also depends upon the nature of the corrosive environment.
Factors like high-temperature water, along with Carbonization and chlorination, static stress, and material properties.
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.
