I think the correct answer is B
Answer:
1) The change in storage of the catchment is 707676800 cubic meters.
2) The runoff coefficient of the catchment is 0.83.
Explanation:
The water budget equation of the catchment can be written as
where
'P' is volume of precipitation in the catchment =
Is the water inflow
ET is loss of water due to evapo-transpiration
is the change in storage of the catchment
is the outflow from the catchment
I is losses due to infiltration
Applying the values in the above equation and using the values on yearly basis (Time scale is taken as 1 year) we get
Part b)
The runoff coefficient C is determined as
where symbols have the usual meaning as explained earlier

Answer:
Change in length = 0.1257 mm
Change in diameter= -0.03771mm
Explanation:
Given
Diameter, d = 15 mm
Length of rod, L = 200mm
F = Force= 300N
d = 0.015m
Ep=2.70 GPa, np=0.4.
First, we have to calculate the normal stress using
σ = F/A where F = Force acting on the Cross-sectional area
A = Area
Area is calculated as πd²/4 where d = 0.015m
A = 22/7 * 0.015²/4
A = 0.000176785714285m²
A = 1.768E-4m²
So, stress. σ = 300N/1.768E-4m²
σ = 1696832.579185520Pa
σ = 1.697MPa
Calculating E(long)
E(long) = σ /Ep
E(long) = 1.697E-3/2.70
E(long) = 0.0006285
At this point, we fan now calculate the change in length of the element;
∆L = E(long) * L
∆L = 0.0006285 * 200mm
∆L = 0.1257mm
Calculating E(lat)
E(lat) = -np * E(long)
E(lat) = -4 * 0.0006285
E(lat) = -0.002514
At this point, we can now calculate the change in diameter of the element;
∆D = E(lat) * D
∆L = -0.002514 * 15mm
∆L = -0.03771mm
The number of hours that must be travelled by car to make the risks of fatality by car equal to the risk of fatality by rock climbing is = 65hours
<h3>Calculation of risk of fatalities (FAR)</h3>
The FAR of car = 52
This means for every one hour there is risk of 52 people dying by car accident.
The FAR of rock climbing = 3400
This means that for every one hour there is risk of 3400 dying by car accident.
If FAR for 1 hour = 52
X hours = 3400
Make X the subject of formula,
X hours = 3400/52
= 65 hours approximately
Therefore, the number of hours that must be travelled by car to make the risks of fatality by car equal to the risk of fatality by rock climbing is = 65 hours.
