A20 dbm power source is connected to the input of a directional coupler having a coupling factor of 20 db, a directivity of 35 db, and an insertion loss of 0.5 db. if all ports are matched, find the output powers (in dbm) at the through, coupled, and isolated ports.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
