I believe the answer is D: brazing
Hope this helps you have a good night
Answer:
And Im still going with B..
Answer:288 pm
Explanation:
Number of atoms(s) for face centered unit cell -
Lattice points: at corners and face centers of unit cell.
For face centered cubic (FCC), z=4.
- whereas
For an FCC lattices √2a =4r =2d
Therefore d = a/√2a = 408pm/√2a= 288pm
I think with this step by step procedure the, the answer was clearly stated.
Answer:
Isolated system
Explanation:
By definition of a closed system it means that a system that does not interact with it's surroundings in any manner
The other options are explained as under:
Isothermal system : It is a system that does not allow it's temperature to change
Control Mass system : It is a system whose mass remains conserved which means the mass entering the system equals the mass leaving the system
Open system: It is a system that allows transfer of mass and energy across it's boundary without any opposition i.e freely.
C, I took the test already.
