If current flowing through a conductor is 10 mA. how many electrons travel through it in 10 s?
6.25×10⁻¹⁸ electrons will flow through a copper wire.
What are electrons?Electrons can be defined as the sum of atomic particles that is the career of negative charge, they are responsible for the chemical property of an element, the electrons are present in the shell.
Use formula ( I = ne/t )
Here,
number of electron
electron =1.6 x 10¯¹9 C
We have a relation between charge and current as
Charge = Current×time i.e
Q = i×t.
Now we have current = 10 amp & time = 10sec from given data.
Therefore charge Q = 10×1 = 100 coulombs.
Again we have a relation between charge and no of electrons
I.e no of electrons= total charge / 1.6×10⁻¹⁹
So, no of electrons = ( 100C/1.6×10⁻¹⁸ )
= 6.25×10⁻¹⁸ electrons.

cubical tank 1 meter on each edge is filled with water at 20 degrees C. A cubical pure copper block 0.46 meters on each edge with an initial temperature of 100 degrees C is quickly submerged in the water, causing an amount of water equal to the volume of the smaller cube to spill from the tank. An insulated cover is placed on the tank. The tank is adiabatic. Estimate the equilibrium temperature of the system (block + water). Be sure to state all applicable assumptions.
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:
since tank is adiabatic, there's no heat gain or loss through the wallsthe tank is perfectly full, leaving no room for cooling airtotal heat energy within the tank will be the summation of the heat energy of the copper and the water remaining in the tank.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°

Explanation:
Convert to an equation for example P%* X=Y
P is 7.5% X is 140, so the equation Is 7.5 percent * 14= Y
convert 7.5% Into a decimal by removing the percent sign and deviding by 7.5/100= 0.075
Substitute 0.075 for 7.5% in the equation: 7.5%*140=Y becomes 0.075*140= 10.5
on a hot (30°c) summer day, solar radiation is absorbed on the asphalt at a rate of 625 w/m2. the asphalt surface convects and radiates energy to the surroundings as well as conducting some energy into the ground. assume the natural (or free) convection heat transfer coefficient is 6 w/m2-k. the emissivity of the asphalt is 0.8. the asphalt is 2 inches thick and has a thermal conductivity of 0.062 w/m-k. the temperature of the ground under the asphalt is 18.9°c. calculate the steady-state temperature of the asphalt in °c. will it be high enough to "fry an egg"? ideal pan temperature to fry an egg is 60-71°c.
The steady state temperature of asphalt will be 75.32°C .
Given,
Solar radiation is absorbed on the asphalt at a rate of 625 w/m² .
Convection heat transfer coefficient is 6 w/m²-k .
Emissivity of the asphalt is 0.8.
Thermal conductivity of 0.062 w/m-k.
Asphalt is 2 inches thick
2 inches = 0.0508m
Surrounding temperature = 30°C = 86°F = 303 k
Asphalt temperature = 18.9°C = 292 k
Now,
Heat absorbed by asphalt = Heat lost by asphalt due to conduction , convection , radiation .
Let temperature of surface of asphalt be Ta
Q(conduction) = Ta - Tg/L/K(A)
Q(convection) = Ha(Ta - Tg)
Q(radiation) = ∈σ(\(Ta^4\) - \(Tg^4\))
Now substitute the values in the formula,
Q(radiation) = 0.8 * 5.67 * \(10^{-8}\)(\(303^4\) - \(Ta^4\)) W/m²
Q(Total) = Q(radiation) + Q(convection) + Q(conduction)
625 = 0.8 * 5.67 * \(10^{-8}\)(\(303^4\) - \(Ta^4\)) + 6(303 - Ta) + Ta - 292/0.819355
Q(conduction) = Ta - 292/0.0508/0.062
Q(conduction) = 1.225(Ta - 292) W/m²
Q(convection) = 6(303 - Ta)
Now solving for Ta,
\(4.536 * 10^{-8} Ta^4\) + 7.2205Ta = 3181.712483

A square (10 mm × 10 mm) silicon chip is insulated on one side and cooled on the opposite side by atmospheric air in parallel flow at u[infinity] = 20 m/s and T[infinity] = 24°C. When in use, electrical power dissipation within the chip maintains a uniform heat flux at the cooled surface. If the chip temperature may not exceed 80°C at any point on its surface, what is the maximum allowable power? What is the maximum allowable power if the chip is flush mounted in a substrate that provides for an unheated starting length of 20 mm
The maximum allowable power for the silicon chip when it is flush mounted in a substrate with an unheated starting length of 20 mm is 0.136 W.
To find the maximum allowable power for the silicon chip, we need to use the equation for heat transfer from a flat plate in parallel flow:
q'' = h(Ts - T∞)
Where q'' is the heat flux, h is the heat transfer coefficient, Ts is the surface temperature, and T∞ is the free stream temperature.
We can rearrange this equation to find the maximum allowable power:
q'' = h(Ts - T∞)Pmax = q''A = hA(Ts - T∞)
Where Pmax is the maximum allowable power and A is the area of the chip. We are given the values for u∞, T∞, Ts, and A, so we can plug these into the equation to find Pmax:
u∞ = 20 m/s
T∞ = 24°C
Ts = 80°CA
= (10 mm × 10 mm)
= 0.0001 m²
We also need to find the value for h, which we can do using the equation for the Nusselt number for a flat plate in parallel flow:
\(NuL = 0.664Re^{0.5}Pr^0.33\)
Where NuL is the Nusselt number, Re is the Reynolds number, and Pr is the Prandtl number. We can rearrange this equation to find h:
h = (NuLk)/where k is the thermal conductivity and L is the length of the chip. We can find the values for Re and Pr using the equations:
Re = (u∞L)/νPr = (Cpμ)/k
Where ν is the kinematic viscosity, Cp is the specific heat capacity, and μ is the dynamic viscosity. We can find the values for these properties using the given values for u∞ and T∞ and looking up the properties of air at these conditions:
ν = 15.68 × 10^-6 m²/s
Cp = 1007 J/kg·Kμ
= 18.46 × 10^-6 kg/m·sk
= 0.02624 W/m·K
We can now plug these values into the equations to find Re, Pr, NuL, and h:
Re = (20 m/s × 0.01 m)/(15.68 × 10^-6 m²/s)
= 12755.1Pr =
(1007 J/kg·K × 18.46 × 10^-6 kg/m·s)/(0.02624 W/m·K)
= 0.708NuL
= 0.664(12755.1^0.5)(0.708^0.33)
= 59.58h
= (59.58 × 0.02624 W/m·K)/0.01 m
= 155.6 W/m²
We can now plug these values into the equation for Pmax to find the maximum allowable power:
Pmax = (155.6 W/m²·K)(0.0001 m²)(80°C - 24°C) = 0.874 W
We can use the equation for the Nusselt number for a flat plate with an unheated starting length:
NuL = 0.3387(ReLPr)^(1/3)
Where L is the length of the heated portion of the plate.
We can plug in the values for Re, Pr, and L to find NuL:
NuL = 0.3387(12755.1 × 0.01 m × 0.708)^(1/3)
= 9.23
We can now use this value for NuL to find a new value for h:
h = (9.23 × 0.02624 W/m·K)/0.01 m = 24.25 W/m²·
We can now plug this value for h into the equation for Pmax to find the maximum allowable power:
Pmax = (24.25 W/m²·K)(0.0001 m²)(80°C - 24°C)

An elastic cable is to be designed for bungee jumping from a tower 130 ft high. The specifications call for the cable to be 85 ft long when unstretched, and to stretch to a total length of 100 ft when a 750-lb weight is attached to it and dropped from the tower.
Determine:
a. The required spring constant k of the cable.
b. How close to the ground a 185-lb man will come if he uses this cable to jump from the tower?
Answer:
a) The spring constant is 50 lb/ft
b) The man is 26.3 ft close to the ground.
Explanation:
Height of tower is 130 ft
Specification calls for a cable of length 85 ft
the maximum this length stretches is 100 ft when subjected to a load of 750 lb
The extension of the cable is calculated from the formula from Hooke's law
F = kx
where F is the load or force on the cable
k is the spring constant of the cable
x is the extension on the cable
a) The extension on the cable is
x = 100 ft - 85 ft = 15 ft
substituting into the formula above, we'll have
750 = k*15
k = 750/15 = 50 lb/ft
b) for a 185 lb man, jumping down will give an extension gotten as
F = kx
185 = 50*x
x = 185/50 = 3.7 ft
The total length of the cable will be extended to 100 ft + 3.7 ft = 103.7 ft
closeness to the ground = 130 ft - 103.7 ft = 26.3 ft

This assignment is about your project Mazer: Vision and Scope The due date: Thursday, September 8, 2022 at 1.00PM. Here are the details for the initial implementation of your project Mazer (Math Analyzer for mazers). At this stage, think about how you will implement it. We will discuss your ideas next week in class. 1. The Mazer is command line, as discussed in class. 2. Alphabet consists of: 0−9,+,−(,),space,tab. 3. Valid forms: integers - int (can be signed - single, parenthesized - multiple) 4. White space is ignored, except between a+/− and int 5. Accept an input and indicate "Valid" "Invalid". 6. Repeat until the user enters 0. 7. + - must be followed by an int or something that evaluates to int. A + or - cannot follow a+ or −. 8. Any other forms of mazer are invalid. Example of valid mazers: 123,+1 1
,(1) etc. Examples of invalid mazers: 1+,++, (1 etc. Please implement the Mazer requirements in a language of your choice. As discussed in class, you must not use an evaluator, but read input chracter by character. Submit requirements, commented code, sample outputs, and test suites. Due: October 6,2022 by class time.

A system will never enter a deadlocked state if:__________A) the system chooses to ignore the problem altogether.B) the system uses the detection and recovery technique.C) the system uses the deadlock avoidance technique.D) None of the above.
A system will never enter a deadlocked state if the system uses the detection and recovery technique. Thus the correct option is B.
What is deadlocked state?A deadlock in desktop software happens when a procedure or task enters a waiting state as a result of another waiting process holding the requested system resource.
When a group of processes is in a wait state, a deadlock occurs because each process is awaiting a resource that is being held by another waiting process.
The wait-for graph must be maintained by the system in order to detect deadlocks, and the system periodically runs an operation that looks for cycles in the wait-for graph.
There is no method used by the OS to avoid or stop deadlocks. The OS checks the system on a regular basis for any deadlocks in an effort to break them. Therefore, option B is appropriate.

When a company converts from one system to another, it affects many areas within the organization. Let's discuss how this conversion will affect different groups individually and collectively:
The conversion to a new system will impact employees in various ways. They may need to undergo training to learn how to operate the new system effectively. This training could be time-consuming and may require them to adapt to new processes and procedures. Employees who were previously familiar with the old system may initially experience a learning curve as they become accustomed to the new system. However, once they become proficient, the new system may offer improved efficiency and productivity.
The conversion to a new system will require the involvement of management at different levels. They will be responsible for overseeing the transition process and ensuring that it is carried out smoothly. They may need to allocate resources, such as time and budget, to support the conversion. Additionally, management will need to communicate the reasons behind the conversion to the employees and address any concerns or resistance that may arise during the transition.
