Athin uniform rectangular plate (lamina) is of mass m and dimensions 2a by a. choose a coordinate system oxyz such that the plate lies in the xy plane with origin at a corner, the long dimension being along the x-axis. find the following: (a) the moment of inertia tensor about the origin (b) the principal moments of inertia about the origin (c) the angular momentum about the origin if the plate is spinning with angular rate about the diagonal through the origin cottcides wnth he 0in rehret to an ineria frame of wich the onigin coincides with the oxyz system.

what are the options.

explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
