Answer:
amount of electric charge transported = 1.13 × C
Explanation:
given data
electric current = 237.0 mA = 0.237 A
time = 8 min = 8 × 60 sec = 480 sec
solution
we get here amount of electric charge transported that is express as
amount of electric charge transported = electric current × time ...........1
put here value and we get
amount of electric charge transported = 0.237 × 480
amount of electric charge transported = 113.76 C
amount of electric charge transported = 1.13 × C
Answer:
The power input, in kW is -86.396 kW
Explanation:
Given;
initial pressure, P₁ = 1.05 bar
final pressure, P₂ = 12 bar
initial temperature, T₁ = 300 K
final temperature, T₂ = 400 K
Heat transfer, Q = 6.5 kW
volumetric flow rate, V = 39 m³/min = 0.65 m³/s
mass of air, m = 28.97 kg/mol
gas constant, R = 8.314 kJ/mol.k
R' = R/m
R' = 8.314 /28.97 = 0.28699 kJ/kg.K
Step 1:
Determine the specific volume:
p₁v₁ = RT₁
Step 2:
determine the mass flow rate; m' = V / v₁
mass flow rate, m' = 0.65 / 0.81997
mass flow rate, m' = 0.7927 kg/s
Step 3:
using steam table, we determine enthalpy change;
h₁ at T₁ = 300.19 kJ /kg
h₂ at T₂ = 400.98 kJ/kg
Δh = h₂ - h₁
Δh = 400.98 - 300.19
Δh = 100.79 kJ/kg
step 4:
determine work input;
W = Q - mΔh
Where;
Q is heat transfer = - 6.5 kW, because heat is lost to surrounding
W = (-6.5) - (0.7927 x 100.79)
W = -6.5 -79.896
W = -86.396 kW
Therefore, the power input, in kW is -86.396 kW

A plastic deformation is defined as a change in shape of the part between the damaged and undamaged area that is smooth and continuous. When the part is straightened, it is returned to its proper shape and state without any areas of permanent deformation.
Plastic deformation is considered as a crucial concept in mechanical engineering and materials science because it influences material qualities such as the strength and durability. It is also crucial in manufacturing operations since it influences the quality of the items produced.
Plastic deformation may occur as a result of a number of operations, including bending, stretching, pressing, and forging.

Answer:
Digital electronics deals with the discrete-valued digital signals. In general, any electronic system based on the digital logic uses binary notation (zeros and ones) to represent the states of the variables involved in it. Thus, Boolean algebraic simplification is an integral part of the design and analysis of a digital electronic system.

Answer:
x3=0.100167
Explanation:
Let's find the answer.
Because we are going to find the solution for sin(Ф)=0.1 then:
f(x)=sin(Ф)-0.1 and:
f'(x)=cos(Ф)
Because 0<Ф<π/2 let's start with an initial guess of 0.001 (x0), so:
x1=x0-f(x0)/f'(0)
x1=0.001-(sin(0.001)-0.1)/cos(0.001)
x1= 0.100000
x2=0.100000-(sin(0.100000)-0.1)/cos(0.100000)
x2=0.100167
x3=0.100167
