Density of gauge fluid used in well manometer is rho =13600 ±13.6 kg/m3. the maximum height of gauge fluid in the reading scale is h=0.4 m., and uncertainty in reading scale is ± 0.1 mm. compute the absolute uncertainty and accuracy of this well manometer? use g = 10 m/s2 , and one digit after decimal point for results only!

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
