An uphill slope improves the take-off ground run, and a downhill slope increases the landing ground run.

<h3>What is uphill slope?</h3>

Driving uphill suggests climbing a “positive” six percent slope . Driving downhill, the “rise” exists as a drop, so there is a “negative,” or downhill, slope (Figure B). When dealing with slope, a positive slope simply indicates uphill and a negative slope indicates downhill. An uphill slope improves the take-off ground run, and a downhill slope increases the landing ground run.

If something or someone lives moving downhill or is downhill, they exist moving down a slope or are located toward the bottom of a hill. He headed downhill toward the river. adverb. If you communicate that something exists going downhill, you mean that it is becoming worse or less prosperous.

Why can the human powered generator be the worst option for the rescue team

zimovet [89]

Answer:

Human powered generators are the best energy source for the rescue team as it doesn't require any lengthy time consuming resource but only the power of single human being. Just like fossil fuels, the human power is a kind of renewable energy source that does no harm to the environment and can be used whenever required.

A levee will be constructed to provide some flood protection for a residential area. The residences are willing to accept a one-

777dan777 [17]

Answer:

1709.07 ft^3/s

Explanation:

Annual peak streamflow = Log10(Q [ft^3/s] )

mean = 1.835

standard deviation = 0.65

Probability of levee been overtopped in the next 15 years = 1/5

<u>Determine the design flow ins ft^3/s </u>

P₁₅ = 1 - ( q )^15 = 1 - ( 1 - 1/T )^15 = 0.2

∴ T = 67.72 years

Q₁₅ = 1 - 0.2 = 0.8

Applying Lognormal distribution : Zt = mean + ( K₂ * std ) --- ( 1 )

K₂ = 2.054 + ( 67.72 - 50 ) / ( 100 - 50 ) * ( 2.326 - 2.054 )

= 2.1504

back to equation 1

Zt = 1.835 + ( 2.1504 * 0.65 ) = 3.23276

hence:

Log₁₀ ( Qt(ft^3/s) ) = Zt = 3.23276

hence ; Qt = 10^3.23276

= 1709.07 ft^3/s

Answer:

point B where $Q_B = 101.25 \ in^3$ has the largest Q value at section a–a

Explanation:

The missing diagram that is suppose to be attached to this question can be found in the attached file below.

So from the given information ;we are to determine the point that has the largest Q value at section a–a

In order to do that; we will work hand in hand with the image attached below.

From the image attached ; we will realize that there are 8 blocks aligned on top on another in the R.H.S of the image with the total of 12 in; meaning that each block contains 1.5 in each.

We also have block partitioned into different point segments . i,e A,B,C, D

For point A ;

Let Q be the moment of the Area A;

SO ; $Q_A = Area \times y_1$
