Compute the atomic packing factor for the diamond cubic crystal structure. Assume that bonding atoms touch one another, that the angle between adjacent bonds is 109.5°, and that each atom internal to the unit cell is positioned at a/4 of the distance away from the two nearest cell faces (a is the unit cell edge length).

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
