Answer to Question 1

D

Answer to Question 2

Q = wdv
where Q = discharge; w = channel width; d = channel depth; and v = stream velocity.
As Q increases, one or more of the other variables must also increase. So, if discharge and depth remain the same, but width increases, velocity must decrease.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt.
