1.Compute the geodetic coordinates of the station QBN from station MDU If coordinates of station MDU are f = 39°51'55"N, ? = 104°40'58"W Distance = 30km, Az = 243°40'48”, h = 1850m, dh= -20. Ellipsoid GRS80
2.Some hypothetical alloy is composed of 12.5 wt% of metal A and 87.5 wt% of metal B. If the densities of metals A and B are 4.27 and 6.35 g/cm3, respectively, whereas their respective atomic weights are 61.4 and 125.7 g/mol, determine whether the crystal structure for this alloy is simple cubic, face-centered cubic, or body-centered cubic. Assume a unit cell edge length of 0.395 nm.
