The street is a haunting and devastating sight, a testament to the destructive power of the atomic bomb.

"Hiroshima Diary," Dr. Michihiko Hachiya provides a detailed account of the street he sees as he emerges from the rubble of his destroyed hospital in the aftermath of the atomic bomb explosion on August 6, 1945. Dr. Hachiya describes the street as unrecognizable and eerily quiet.

The buildings are in ruins, and there are no signs of life except for a few injured and dying people lying in the streets. Dr. Hachiya notes that the air is filled with a "strange and pungent odor," which he later learns is the smell of burnt flesh. Despite the destruction, Dr. Hachiya observes that there are still some trees standing, though they are stripped of leaves and branches, and some street lamps are still intact.

The unit weight of the saturated silty clay is approximately 34.625 kN/m³.

The formula is:
y = (1 + w) * G * \(y_w\)

We have the following variables

γ = Unit weight of the clay

w = Water content of the clay

G = Specific gravity of the clay particles

\(y_w\) = Unit weight of water

water content is given as (w) = 28%

Specific gravity (G) = 2.7

we can now calculate the unit weight of the clay:

γ = (1 + 0.28) * 2.7 * 9.81

γ = 34.625 kN/m³

Therefore, the unit weight of the saturated silty clay is approximately 34.625 kN/m³.

Answer:

It's to ensure a driver's safety.

Answer:

The typical structure of a report, as shown on this page, is often referred to as IMRAD, which is short for Introduction, Method, Results And Discussion. As reports often begin with an Abstract, the structure may also be referred to as AIMRAD.

Answer:

a) the moisture content before it was placed in the oven is 18.18%

b) degree of saturation for soil is 72.19%

Explanation:

Given the data in the question;

Moisture Content = [(Weight of soil before dry - dry weight) / dry weight] × 100

so we substitute

Moisture content = [(53.3 - 45.1) / 45.1 ] × 100

= (8.2/45.1) × 100

= 18.18%

Therefore the moisture content before it was placed in the oven is 18.18%

Dry Unit Weight = dry weight / volume

Dry Unit Weight = 45.1 lb / 0.45 ft³

Dry Unit Weight = 100.22 lb/ft³

we know that;

dry unit weight = (Specific gravity × unit weight of water) / (1 + e)

we also know that; unit weight of water is 62.43 lbf/ft³

so we substitute

e = (2.70×62.43 / 100.22) - 1

e = 1.68 - 1

e = 0.68

so void ratio e = 0.68

Now we determine the degree of saturation using the equation;

degree of saturation = (Moisture content × specific gravity) / void ratio

we substitute

degree of saturation = ( 18.18% × 2.7) / 0.68

= 0.49086 / 0.68

= 0.7219 ≈ 72.19%

Therefore degree of saturation for soil is 72.19%

When heating a fixed mass of an ideal gas from 50 to 80 degrees Celsius at constant pressure, the energy required will be greater for the sample at 3 atm compared to 1 atm.

In the second question, when heating air at constant pressure from 250 to 350 K and from 450 to 550 K, both cases will require the same amount of energy as the specific heat of an ideal gas does not vary with temperature.

In the first scenario, when heating the gas from 50 to 80 degrees Celsius at constant pressure, the energy required is directly proportional to the change in temperature. Since the temperature change is the same for both cases (30 degrees Celsius), the energy required will be greater for the sample at 3 atm because it experiences a larger pressure, resulting in a higher energy requirement.

In the second scenario, when heating air at constant pressure, the energy required is determined by the temperature change, not the specific temperatures themselves. The specific heat of an ideal gas does not vary with temperature, meaning the energy required will be the same for both cases. The difference in initial and final temperatures is the same (100 K) for both samples, resulting in an equal energy requirement.

Therefore, in both cases, the energy required is greater for the sample at 3 atm in the first scenario, and the energy requirements are the same for both samples in the second scenario due to the properties of ideal gases and constant pressure conditions.

Explanation:

Answer:

final temperature = 26.5°

Explanation:

Initial volume of water is 1 x 1 x 1 = 1 \(m^{3}\)

Initial temperature of water = 20° C

Density of water = 1000 kg/\(m^{3}\)

volume of copper block = 0.46 x 0.46 x 0.46 = 0.097 \(m^{3}\)

Initial temperature of copper block = 100° C

Density of copper = 8960 kg/\(m^{3}\)

Final volume of water = 1 - 0.097 = 0.903 \(m^{3}\)

Assumptions:

mass of water remaining in the tank will be density x volume = 1000 x 0.903 = 903 kg

specific heat capacity of water c = 4186 J/K-kg

heat content of water left Hw = mcT = 903 x 4186 x 20 = 75.59 Mega-joules

mass of copper will be density x volume = 8960 x 0.097 = 869.12 kg

specific heat capacity of copper is 385 J/K-kg

heat content of copper Hc = mcT = 869.12 x 385 x 100 = 33.46 Mega-joules

total heat in the system = 75.59 + 33.46 = 109.05 Mega-joules

this heat will be distributed in the entire system

heat energy of water within the system = mcT

where T is the final temperature

= 903 x 4186 x T = 3779958T

for copper, heat will be

mcT = 869.12 x 385 = 334611.2T

these component heats will sum up to the final heat of the system, i.e

3779958T + 334611.2T = 109.05 x \(10^{6}\)

4114569.2T = 109.05 x \(10^{6}\)

final temperature T = (109.05 x \(10^{6}\))/4114569.2 = 26.5°

Social engineering is considered as both an art and a science. It is a form of hacking that involves the manipulation of victims through social interaction instead of directly breaking into a computer system.

The logic behind social engineering is simple, if one knows how to trick a person into giving out the data they need, they can easily access all the information and access they need with the least resistance possible. This makes social engineering a crucial part of hacking since it allows hackers to gain access to devices, accounts, or applications without making any additional effort.

By using social engineering tactics, a hacker can access a system without having to go through all the other hijacking tactics up their sleeve.The most challenging part of social engineering is securing trust, which is only possible by getting someone's trust. Hackers use various tactics to predict possible responses from a person whenever they are triggered to perform any action in relation to their security system.

The ability to read possible responses from a person is a significant skill for hackers since it enables them to predict passwords and other valuable computer assets without having to use too many tools. Successful hackers use social engineering as a powerful tool to penetrate a system.

In conclusion, social engineering is an essential component of hacking, and a significant part of its success lies in the art of manipulation.

A pre-timed four-timing-stage signal has critical lane group flow rates for the first three timing stages of 200, 187, and 210 veh/h (saturation flow rates are 1800 veh/h/ln for all timing stages). The lost time is known to be 4 seconds for each timing stage. If the cycle length is 60 seconds,

In the given problem, it is known that the lost time for each timing stage is 4 seconds and that the cycle length is 60 seconds. The total time lost in the three timing stages is therefore\(3 × 4 = 12\)seconds.

The sum of the critical flow rates for the first three timing stages is \(200 + 187 + 210 = 597 veh/h\).The saturation flow rate for each timing stage is \(1800 veh/h/ln\).

There are 4 lanes, therefore, the saturation flow rate for 4 lanes will be \(4 x 1800 = 7200 veh/h\). Saturation flow rate - critical flow rate = unused time = \(7200 - 597 = 6603 veh/h\)

Now we must divide the unused time by 60 seconds to get the estimated effective green time.

\(6603 / 60 = 110.05 veh/s\)

Since\(110.05 veh/s\) is equivalent to \(6603 veh/min\)and the estimated effective green time is in minutes, we must divide by \(60.6603 / 60 = 110.05 veh/s\)

Therefore, the estimated effective green time of the fourth timing stage is approximately 110 seconds.

a) \(\mathbf{Q_c = -3730.8684 \ Btu/hr}\)

b) \(\mathbf{\sigma _c = 4.3067 \ Btu/hr ^0R}\)

Explanation:

From the properties of Super-heated Refrigerant 134a Vapor at \(T_1 = 40^0 F\), \(P_1 = 30 \ lbf/in^2\) ; we obtain the following properties for specific enthalpy and specific entropy.

So; specific enthalpy \(h_1 = 109.12 \ Btu/lb\)

specific entropy \(s_1 = 0.2315 \ Btu/lb.^0R\)

Also; from the properties of saturated Refrigerant 134 a vapor (liquid - vapor). pressure table at \(P_2 = 160 \ lbf/in^2\) ; we obtain the following properties:

\(h_2 = 115.91 \ Btu/lb\\\\ s_2 = 0.2157 \ Btu/lb.^0R\)

Given that the power input to the compressor is 2 hp;

Then converting to  Btu/hr ;we known that since 1 hp = 2544.4342 Btu/hr

2 hp = 2 × 2544.4342 Btu/hr

2 hp = 5088.8684 Btu/hr

The steady state energy for a compressor can be expressed by the formula:

\(0 = Q_c -W_c+m((h_1-h_e) + \dfrac{v_i^2-v_e^2}{2}+g(\bar \omega_i - \bar \omega_e)\)

By neglecting kinetic and potential energy effects; we have:

\(0 = Q_c -W_c+m(h_1-h_2) \\ \\ Q_c = -W_c+m(h_2-h_1)\)

\(Q_c = -5088.8684 \ Btu/hr +200 \ lb/hr( 115.91 -109.12) Btu/lb \\ \\\)

\(\mathbf{Q_c = -3730.8684 \ Btu/hr}\)

b)  To determine the entropy generation; we employ the formula:

\(\dfrac{dS}{dt} =\dfrac{Qc}{T}+ m( s_1 -s_2) + \sigma _c\)

In a steady state condition \(\dfrac{dS}{dt} =0\)

Hence;

\(0=\dfrac{Qc}{T}+ m( s_1 -s_2) + \sigma _c\)

\(\sigma _c = m( s_1 -s_2) - \dfrac{Qc}{T}\)

\(\sigma _c = [200 \ lb/hr (0.2157 -0.2315) \ Btu/lb .^0R - \dfrac{(-3730.8684 \ Btu/hr)}{(40^0 + 459.67^0)^0R}]\)

\(\sigma _c = [(-3.16 ) \ Btu/hr .^0R + (7.4667 ) Btu/hr ^0R}]\)
