Some two-phase metal alloy is known to be composed of α and β phases; mass fractions of these phases are 0.77 and 0.23, respectively. room-temperature electrical resistivity and density data for these phases are tabulated below. using this information, calculate the electrical resistivity (in ω-m) of the alloy at room temperature.

sorry what a asnns

explanation:

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.
