Q34;

A woman with mass 50 kg is standing on the rim of a large disk that is rotating at 0.80 rev/s about an axis through its center. The disk has mass 270 kg and radius 4.0 m.

Calculate the magnitude of the total angular momentum of the woman–disk system. (Assume that you can treat the woman as a point.)

Express your answer to two significant figures and include the appropriate units.

 

 

 

2.) a.) Calculate the planar atomic density on the (110) plane of a-iron, a bcc structure. The lattice constant is 0.287 nm. b.) What is the angle between the directions [110] and [112]? Determine the Miller indices of the planes A and B shown in the following cubic unit cell. +2 3.) Sketch the atomic positions for a (111) plane in a fcc crystal. For this plane, calculate the planar density and compare this density with that for a (100) plane in the same fcc crystal.
