chinook salmon physics
A Chinook Salmon has a maximum underwater speed of 3.58 m/s, but itcan jump out of water with a speed of 6.08 m/s. To move upstream past a waterfall, thesalmon doesnot need to jump to the top of the fall, but only to apoint in the fall where the water speed is less than 3.58 m/s; itcan then swim up the fall for the remainingdistance. Because thesalmon must make forward progress in the water, let's assume thatit can swim to...

1-An advantage of one-way communication over two-way is the fact that A-fewer mistakes or problems are likely to arise as work progresses. B-the receiver is more likely to understand what to do with the message. C-feedback allows for suggestions and modifications. D-communication is faster and easier. E-it is more accurate communication that ensures clarity. 2-A disadvantage of oral communication is that the A-sender has no control over where, when, or if the message is received. B-message is less persuasive than...
