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.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
