_______ is usually measured in cubic meters per second. A. Discharge B. Bed load C. Flooding D. Suspension
2 answers:
Answer: Option (A) is the correct answer.
Explanation:
In hydrology, the volumetric flow of rate of water that is transported with the help of a given cross-sectional area is known as discharge.
The formula to calculate discharge is as follows.
Q = A u
where,
Q = discharge
A = cross-sectional area of protion of channel occupied by flow (in )
u = average flow velocity (in m/s or ft/s)
Thus, we can conclude that discharge is usually measured in cubic meters per second.

Answer:
C) In[reactant] vs. time
Explanation:
For a first order reaction the integrated rate law equation is:
where A(0) = initial concentration of the reactant
A = concentration after time 't'
k = rate constant
Taking ln on both sides gives:
Therefore a plot of ln[A] vs t should give a straight line with a slope = -k
Hence, ln[reactant] vs time should be plotted for a first order reaction.
