16 the oxygen sag caused by a cannery reaches a minimum do equal to 3.0 mg/l. upstream from the cannery, the river do is saturated at 10.0 mg/l, and it has no bod of its own. just downstream from the discharge point, the do is still essentially saturated (i. e., consider the initial oxygen deficit to be zero so the downstream deficit is propositional to the initial bod). by what percentage should the bod of the cannery waste be reduced to assume a healthy stream with at least 5.0 mg/l do everywhere?

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)

answer:

Power braking's benefits

Among the big advantages of a power braking system are it's: Regarded as safer. The heat caused by the friction of drum brakes causes them to wear down. Because disc brake systems have better heat distribution, they're more efficient
