Solution :
1. PL [tex]$= \frac{11.53 - 10.49}{10.49 - 4.5} \times 100$[/tex]
= 17.36 %
2. Liquid limit at 25 number of blows,
[tex]$LL = \frac{(26-25)\times 49.8 + (25 - 2.17) \times 47.5}{26-17}$[/tex]
[tex]$= 47.75 $[/tex] %
Since 84 % of the passes the number 200 sieve the soil is immediately fine grained and MI, OI or CI because LL = 47.75 % > 35%
Therefore, the Plasticity index, PI [tex]$=47.75 - 17.36 = 30.39$[/tex] %
Equation of A-line [tex]$= 0.73 \times [47.75 - 20]$[/tex]
[tex]$=20.25 $[/tex] %
Thus the soil lies above the A-line, that is soil is medium compressible clay ---- CI
When the mass of an object decreases, the force of gravity does what?
Answer:
decreases too
Explanation:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Answer:
decreases
Explanation:
Since the gravitational force is directly proportional to the mass of interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases (decreases), the force of gravitational attraction between them also increases (decreases).

You'll need to use Ohm's Law and Kirchhoff's Voltage Law.
Remember Ohm's Law as [tex]V = IR[/tex].
Kirchoff's Voltage Law says that the sum of voltages for a given circuit "loop" must equal zero. In the circuit shown, this means that the voltage provided by the battery (E_T) equals the voltage drop across each of the three resisters in the loop.
[tex]E_T = E_1 + E_2 + E_3[/tex]
A couple of other helpful notes:
These three resistors are in series which means that the current flowing through them is equal.
So it is easy to see that... [tex]V = IR \rightarrow E_1 = 4*2 = 8 V[/tex]
Solve for the voltage across E_2 and E_3. The sum of the three voltages equals the voltage of the battery (E_T).

Answer:
Hello the circuit related to this question is missing attached below is the missing circuit
answer : 1.5 V
Explanation:
attached below is the detailed solution to the question
Applying Thevenin equivalent Circuit Theorem
First we perform Nodal analysis at Vth and draw the equivalent Thevenin circuits
Hence for a maximum power triangle
[tex]V_{RL} = \frac{V_{th} }{2} = \frac{-3}{2}[/tex] = -1.5
therefore the value of v that maximizes the power dissipated in the voltage source
V = [tex]-V_{RL}[/tex] = 1.5 V
Water flows through this orifice meter by gravity. The orifice diameter is 50 cm and water height difference is 10 m. If the contraction coefficient is 0.62 and velocity coefficient is 0.90, the flow rate through the orifice is most nearly:
Answer:
Q ≅ 1.53 m³/s
Explanation:
From the given information:
The flow rate of the orifice is:
[tex]v = c_v \sqrt{2gh}[/tex]
[tex]v = 0.90 \times \sqrt{2*9.81 * 10}[/tex]
where;
[tex]Q = c_d \times \sqrt{2gh} \times A[/tex]; &
[tex]c_d = c_c \times c_v[/tex]
∴
[tex]Q = c_c \times c_v \sqrt{2gh} \times \dfrac{\pi}{4}\times d^2[/tex]
[tex]Q = 0.90 \times 0.62 \sqrt{2*9.81*10} \times \dfrac{\pi}{4}\times 0.5^2[/tex]
[tex]Q = 0.558 \times 14.00714104 \times 0.1963495408[/tex]
Q ≅ 1.53 m³/s
For the velocity fields given below, determine:
a) whether the flow field is one-, two-, or three-dimensional,
b) whether the flow is steady or unsteady, and why. (The quantities a and b are constants.)
1. V = [ay2e−bt]i
2. V = ax^2i + bxj + ck
3. V = axyi - bytj
4. V = axi - byj + ctk
Answer and Explanation: A fluid flow is steady when its properties (velocity, pressure and others) do not change over time: P = P(x,y,z), with P being any of the properties.
So, an unsteady flow does depend upon time: P = P(x,y,z,t).
1. V = [[tex]ay2e^{-bt}[/tex]]i : This velocity field is one-dimension, because there is only the component in the x-direction and unsteady, because it is dependent upon the variable time (t);
2. V = [tex]ax^{2}i+bxj+ck[/tex] : is a three-dimensional field, because there is one component for each direction (x, y and z) and is steady, since it's independent of time;
3. V = axyi - bytj : is a 2-dimensional field, and since it changes with time, it is unsteady;
4. V = axi - byj + ctk : is a 3-dimensional field and the flow is unsteady;

g Asbestos is a fibrous silicate mineral with remarkably high tensile strength. But is no longer used because airborne asbestos particles can cause lung cancer. Grunerite, a type of asbestos, has a tensile strength of 3.5 × 10ଶ kg mmଶ ⁄ (meaning a strand of grunerite with a 1-mmଶ cross-sectional area can hold up to 3.5 × 10ଶ kg). The tensile strength of aluminum and Steel No. 5137 are 2.4 × 10ସ lb inଶ ⁄ and 5.0 × 10ସ lb inଶ ⁄ respectively. Calculate the cross section areas in mmଶ of wires of aluminum and of Steel No. 5137 that have the same tensile strength as a fiber of grunerite with a cross-sectional area of 1.0 μmଶ
Answer:
Aluminum cross sectional area = 1.99 * 10^-5 mm^2
Steel cross sectional area = 9.95* 10^-6 mm^2
Explanation:
Given data:
Tensile strength of Grunerite = 3.5 * 10^2 kg/mm^2 = 3.5 * 10^-4 kg/um^2
Tensile strength of Aluminum = 2.5 × 10^4 lb/in2 = 2.5 × 10^4 * 703.07 kg/m^2
Tensile strength of Steel number 5137 = 5.0 × 10^4 lb/in2 = 5.0 × 10^4*703.07 kg/m^2
Calculating the cross sectional area of the wires of aluminum and steel No5137
first we will determine the cross sectional area of the aluminum wire ( A ) by equating tensile strength of aluminum with the tensile strength
of Grunerite
(2.5 × 10^4 * 703.07) * A = 3.5 * 10^-4 kg
Hence ; A = 1.99 * 10^-5 mm^2
Next we calculate the cross sectional area of steel
5.0 × 10^4*703.07 kg/m^2 * A" = 3.5 * 10^-4 kg
Hence ; A" = 9.95* 10^-6 mm^2
A force of 12 N is applied to a block moving west. Another force of 26 N is being applied in the opposite direction. The block weighs 7kg. What is the net force and the acceleration?
Answer:
[tex]F_{Net} = 14N[/tex]
[tex]a = 2m/s^2[/tex]
Explanation:
Given
[tex]Mass = 7kg[/tex]
[tex]F_{west} = 12N[/tex]
[tex]F_{opposite} = 26N[/tex]
Solving (a): The net force:
The force towards the west direction, will be regarded as negative while the opposite force will be regarded as positive.
So, the net force is:
[tex]F_{Net} = -F_{west} + F_{opposite}[/tex]
Substitute values for the given forces
[tex]F_{Net} = -12N + 26N[/tex]
[tex]F_{Net} = 14N[/tex]
The net force is 14 N
Solving (b): Acceleration
Net force is calculated as:
[tex]F_{Net} = Mass * Acceleration[/tex]
Substitute 7 kg for Mass and 14 N for Net force:
[tex]14N = 7kg* a[/tex]
Make a the subject:
[tex]a = \frac{14N}{7kg}[/tex]
[tex]a = 2N/kg[/tex]
[tex]a = 2m/s^2[/tex]
Hence, the acceleration is [tex]2m/s^2[/tex]

University administrators have developed a Markov model to simulate graduation rates at their school. Students might drop out, repeat a year, or move on to the next year. Students have a 3% chance of repeating the year. First-years and sophomores have a 6% chance of dropping out. For juniors and seniors, the drop-out rate is 4%. Compute the probability that a student who starts as a 1st-year eventually graduates the university.
Solution :
The percentage of the students who have a chance of repeating their current year = 3%
The drop out students for the first year and the sophomores = 6%
Drop out rate of first year and the seniors = 4%
Now for the state space :
S = { first year(1), sophomores(2), juniors(3), seniors(4), graduates(G), Dropouts(D) }
Therefore
the first year students are indicated as '1'
Sophomores are indicated as '2'
Juniors are indicated as '3'
Seniors are indicated as '4
Graduates are indicated as 'G'
Dropouts are indicated as 'D'
The transition diagram is attached below.
The probability of the students who have the chance of repeating their current year = 3/100 = 0.03
Probability of first year dropouts and sophomores = 6/100 = 0.06
Probability of dropout rate of juniors and seniors = 4/100 = 0.04
Therefore, the probability matrix can be made as :
1 2 3 4 G D
[tex]\begin{matrix}1\\ 2\\ 3\\ 4\\ G\\ D\end{matrix}[/tex] [tex]\begin{bmatrix}0.03 & 0.91 & 0 & 0 & 0 & 0.06\\ 0& 0.03 & 0.91 & 0 & 0 & 0.06\\ 0& 0 & 0.03 & 0.93 & 0 & 0.04\\ 0& 0 & 0 & 0.03 & 0.93 & 0.04\\ 0& 0 & 0 & 0 & 1 & 0\\ 0& 0 & 0 & 0 & 0 & 1\end{bmatrix}[/tex]
Here, G represents 'graduates' and D represents 'Dropouts.'
The device shown below contains 2 kg of water. The cylinder is allowed to fall 800 m during which the temperature of the water increases by 2.4°C. Some amount of water is added to the container and the experiment is repeated. All other values remain constant. This time the temperature of the water increases by 1.2°C. How much water was added to the container?
Answer:
m_added = 2 kg
Explanation:
From the question, we are told that the cylinder is allowed to fall 800 m in height. Thus, the potential energy will be converted into heat energy which will increase the temperature of water .
Now, let the mass of the falling cylinder be denoted by "m1" and let h be the height of fall.
Thus;
Formula for potential energy = mgh
Thus, as said earlier it's converted to heat generated. So heat generated = m1gh
Now let's calculate the heat absorbed;
heat absorbed = (m2)cΔt
Where;
ΔT is change in temperature
c is specific heat of water .
m2 is mass of water
Heat absorbed = heat generated
Thus;
(m2)cΔt = m1gh
Δt = m1gh/(m2•c)
Now, in both cases of the water and cylinder, m1, g , h and c are constant
Thus, we have;
Δt = (m1gh/m2) × 1/c
Where;
(m1gh/m2) is denoted as a constant k.
Thus;
Δt = K/m
For the first experiment, we have;
m = 2 kg
Δt = 2.4
Thus;
2.4 = K/2
Multiply both sides by 2 to get;
K = 4.8
For the second experiment, we have;
Δt = 1.2
Also,we have seen that K = 4.8
Thus;
Δt = K/m
Thus;
1.2 = 4.8/m
m = 1.2
m = 4 kg
Thus,mass added is;
m_added = 4 - 2
m_added = 2 kg
Acertain foundation will experience a bearing capacity failure when it is subjected to a downward load of 2200 kN. Using ASD with a factor of safety of 3, determine the maximum allowable loadthat will satisfy geotechnical ULS requirements.
Answer:
550kN
Explanation:
We are required to find the maximum allowable load that will satisfy geotechnical ULS requirements
P' = pu/FOS ---1
Pu = design load
FOS = factor of safety
We get the design of safety
Pu = 0.75p
= 0.75 x 2200
= 1650kN
Factor of safety = 3
Design load = 1650
P' = 1650/3
= 550kN
So we have the maximum allowable load to be 550kN

discuss referencing techniques
Answer:Referencing is a standardised method of acknowledging the sources of information and ideas you have used.
Explanation:Depending on the way in which they record sources, scholarly reference styles can be divided into three main categories: documentary notes styles, parenthetical (or author-date) styles, and numbered styles. Within each category there are several, slightly different reference styles.
Parenthetical citations give a short reference in parentheses directly in the text.Numerical citations give only a number that corresponds to a footnote, endnote, or reference list entry.Referencing allows you to acknowledge the contribution of other writers and researchers in your work. Any university assignments that draw on the ideas, words or research of other writers must contain citations. Referencing is also a way to give credit to the writers from whom you have borrowed words and ideas.

In a certain chemical plant, a closed tank contains ethyl alcohol to a depth of 71 ft. Air at a pressure of 17 psi fills the gap at the top of the tank. Determine the pressure at a closed valve attached to the tank 10 ft above its bottom.
Answer:
the pressure at a closed valve attached to the tank 10 ft above its bottom is 37.88 psi
Explanation:
Given that;
depth 1 = 71 ft
depth 2 = 10 ft
pressure p = 17 psi = 2448 lb/ft²
depth h = 71 ft - 10 ft = 61 ft
we know that;
p = P_air + yh
where y is the specific weight of ethyl alcohol ( 49.3 lb/ft³ )
so we substitute;
p = 2448 + ( 49.3 × 61 )
= 2448 + 3007.3
= 5455.3 lb/ft³
= 37.88 psi
Therefore, the pressure at a closed valve attached to the tank 10 ft above its bottom is 37.88 psi

Explanation:
The characteristics of water flow over a dam spillway are to be measured in a geometrically similar small-scale laboratory model. The width of the prototype is 30 m and the width of the model is 2 m. If the flow in the prototype is 100 m3/s, the flow rate in the model for similitude is:
Answer:
[tex]Q_m \simeq 0.11 \ m^3/sec[/tex]
Explanation:
From the given information:
The width of the prototype [tex]L_p[/tex] = 30 m
The flow of the prototype [tex]Q_p[/tex] = 100 m/s
width of the model [tex]L_m[/tex] = 2 m
The flow rate of the model can be calculated by using the geometrical similarities of Froude's Number Fr
[tex](Fr)_m = (Fr)_p[/tex]
[tex]\implies ( \dfrac{v}{\sqrt{ gy} }) _m = ( \dfrac{v}{\sqrt{gy}}) _p[/tex]
[tex]V_r = \sqrt{L_r}--- (1)[/tex]
[tex]Q_r = V_r *A_r[/tex]
[tex]Q_r = \sqrt { L_r} *L_r^2[/tex]
[tex]Q_r = L_r^{2.5}[/tex]
∴
[tex](\dfrac{Q_m}{Q_p}) = (\dfrac{L_m}{L_p})^{2.5}[/tex]
[tex](\dfrac{Q_m}{100}) = (\dfrac{2}{30})^{2.5}[/tex]
[tex](\dfrac{Q_m}{100}) =0.001147550621[/tex]
[tex]Q_m \simeq 0.11 \ m^3/sec[/tex]
