Interpretation:
The amount of nickel in grams that must be added to copper is to be calculated to give an alloy of desired properties. Also, the ratio of the number of nickel atoms to copper atoms in this alloy is to be determined.
Concept Introduction:
On the temperature-composition graph of an alloy, the curve above which the alloys exist in the liquid phase is the liquidus curve. The temperature at this curve is maximum known as liquidus temperature at which the crystals in the alloy can coexist with its melt in the
Solidus curve is the locus of the temperature on the temperature composition graph of an alloy, beyond which the alloy is completely in solid phase. The temperature at this curve is minimum known as solidus temperature at which the crystals in the alloy can coexist with its melt in the thermodynamic equilibrium.
Percentage of a component in an alloy is calculated as:

- What are the steps you will follow in order to check the database and fix any problems with it? Have in mind that you SHOULD normalize it as well. Describe in full, consider the following:• Taking the database offline is not allowed since people are connected to it.• Personal data might be bridged and not secured. Provide three refernces with you answerarrow_forwardYou are called by your supervisor to go and check a potential data bridge problem.

Provide three refernces with you answerarrow_forwardHere the Req is 8 my prof solved it and got R3 is parallel to R4 in series with R2 and this combination is parallel to R1. i don't understand how he got these relationships. initially i did the opposite i took (R1//R4 + R2 ) + R3 but got the wrong answer why is it wrong? can you explain to me if there's a trick i can do to understand these questions better and know the configurations of the resistors in a better manner?arrow_forward
