Anarrow taper bore is inspected using the precision spheres technique. the taper is 80mm long. the top of a 20mm sphere is 50mm from the wide end of the bore and the top of a 25mm sphere is 5mm also from the wide end of the bore. determine the half angle of the taper and the entry and exit diameters of the bore.

explanation:  

an electrode is a metal whose surface serves as the location where oxidation-reduction equilibrium is established between the metal and what is in the solution.

answer:

in baseband transmission the whole bandwidth of the cable is utilized by a single signal. eg.Ethernet is using Basebands for LAN.

In the broadband transmission, multiple signals are sent on multiple frequencies simultaneously using a single channel. eg.Digital Subscriber Line (DSL)
