The equilibrium fraction of lattice sites that are vacant in silver (Ag) at 700°C is 2 x 10-6. Calculate the number of vacancies (per meter cubed) at 700°C. Assume a density of 10.35 g/cm3 for Ag, AAg = 107.87 g/mol.

Same length is comparing because it’s saying its the same and not different

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
