Answer:
(C) passive state.
Explanation:
The earth pressure is the pressure exerted by the soil on the shoring system. They are three types of earth pressure which are:
a) Rest state: In this state, the retaining wall is stationary, this makes the lateral stress to be zero.
b) Active state: In this state, the wall moves away from the back fill, this leads to an internal resistance. Hence the active earth pressure is less than earth pressure at rest
c) Passive state: In this state the wall is pushed towards the back fill, this leads to shearing resistance. Hence, the passive earth pressure is greater than earth pressure at rest
Answer:
1072 acre foot
1331424000 kg
Explanation:
1 feet has 12 inches, so 2 in is 0.167 feet.
1 km^2 has 1 million m^2.
1 acre is 4074 m^2.
So, 1 km is 247 acres.
Then 26 km^2 is 6422 acres.
So, the volume of water is
6422 * 0.167 = 1072 acre-foot
Since one cubic meter of water has 1000 kg
One inch is 25.4 mm = 0.0254 m
One feet is 12 * 0.0254 = 0.3048 m
An acre-feet has a volume of
4074*0.3048 = 1242 m^3
And that is a mass of water of
1242 * 1000 = 1242000 kg/acre-feet
Therefore the mass of rainwater in the town is of
1072 * 1242000 = 1331424000 kg = 1331424 tons
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.
