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.

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

Argon, neon, and xenon are examples of
