Answer: Rc = 400 Ω and Rb = 57.2 kΩ
Explanation:
Given that;
VCE = 5V
VCC = 15 V
iC = 25 mA
β = 100
VD₀ = 0.7 V
taking a look at the image; at loop 1
-VCC + (i × Rc) + VCE = 0
we substitute
-15 + ( 25 × Rc) + 5 = 0
25Rc = 10
Rc = 10 / 25
Rc = 0.4 k
Rc = 0.4 × 1000
Rc = 400 Ω
iC = βib
25mA = 100(ib)
ib = 25 mA / 100
ib = 0.25 mA
ib = 0.25 × 1000
ib = 250 μAmp
Now at Loop 2
-Vcc + (ib×Rb) + VD₀ = 0
-15 (250 × Rb) + 0.7 = 0
250Rb = 15 - 0.7
250Rb = 14.3
Rb = 14.3 / 250
Rb = 0.0572 μ
Rb = 0.0572 × 1000
Rb = 57.2 kΩ
Therefore Rc = 400 Ω and Rb = 57.2 kΩ
Answer:
Slot screw driver can be used that way but I wouldn't recommend it
Answer:
A. from zero at the center to maximum at the circumference.
Explanation:
The shear stress describes the process where a body deforms as a result of a part sliding over the other.
The value of shear stress which is induced in the shaft due to the applied couple varies from zero at the center to maximum at the circumference.
The shear stress in a shaft is given by this formula;
τ = Tr/I
where;
τ = shear stress (MPa).
T = applied torque (Nmm).
r = distance from center to stressed surface in the given position (mm).
I = polar moment of Inertia of cross-sectional area (mm).
Width * Length * Thickness * Density = Weight.
48″ * 96″ * . 1875″ * 0.284 lb/in3 = 245 lb.
The software industry is evolving, and software certification is crucial. Software certification is a digitally signed certificate that verifies the identification of an individual or company.
<h3>What is software certification?</h3>
A certificate, sometimes known as a digital certificate, is a special document that has been digitally signed and authenticates the identity of a person or business.
Its validity may be checked using public-key cryptography to make sure that the program or website you are accessing is reliable.
Software developers must demonstrate that their program executes the XBRL conformance suites successfully in order to be certified.
They must also supply extra test cases so that XBRL employees can test the program further. The validity of certification is one year, renewable yearly.
Hence the software industry is evolving, and software certification is crucial.
