Answer:

80.9 db.

Explanation:

So, in this particular Question/problem we need to determine/calculate for the the worst possible CMRR. The data or information provided by the Question above;

=> ''amp differential amplifier is built using four identical resistors''

Therefore, R1 = R2 = R3 = R4. From the question above, we also know that the tolerance is ±5% for resistor that is;

A1 = A2 = A3 = A4 = A ±5%.

Using the kirchoff formula to each case, we have;

(1). Non Inverting terminal:

[ J - J2 / (A1 = A3) ] + J/ (A2 = A4) = 0.

J = 0.53 J2.

(2). Inverting terminal:

[ J_ - J2 / (A1 = A3) ] + J_ - Jb / (A2 = A4) = 0.

Thus, Jb = 2.11 J_ - 1.11 J2.

Note that J = J_ = 0.53 J2.

Thus, Jb = 1.11 J2 - 1.11 J1.

(Note that we will have that A2 = A4 = A + 0.05 = 1.05A.

Also, A1 = A3 = A - 0.05 = 0.95A).

The voltage is c1 and c2.

Therefore, Jb = 1.11( ccm + cv/2) - 1.11 ( Ccm - cv/2).

= - 10^-4 ccm - 1.11 cv.

Thus, CMMR = 20 log [| 1.11 ÷ (- 10^-4)|] = 80.9 db.

jeka57 [31]

Answer:

a) at T = 5800 k  

  band emission = 0.2261

at T = 2900 k

  band emission = 0.0442

b) daylight (d) = 0.50 μm

    Incandescent ( i ) =  1 μm

Explanation:

To Calculate the band emission fractions we will apply the Wien's displacement Law

The ban emission fraction in spectral range λ1 to λ2 at a blackbody temperature T can be expressed as

F ( λ1 - λ2, T ) = F( 0 ----> λ2,T) - F( 0 ----> λ1,T )

<em>Values are gotten from the table named: blackbody radiati</em>on functions

<u>a) Calculate the band emission fractions for the visible region</u>

at T = 5800 k  

  band emission = 0.2261

at T = 2900 k

  band emission = 0.0442

attached below is a detailed solution to the problem

<u>b)calculate wavelength corresponding to the maximum spectral intensity</u>

For daylight ( d ) = 2898 μm *k / 5800 k  = 0.50 μm

For Incandescent ( i ) = 2898 μm *k / 2900 k = 1 μm

Air enters a diffuser operating at steady state at 540°R, 15 lbf/in.2, with a velocity of 600 ft/s, and exits with a velocity of
yKpoI14uk [10]

Answer: Hello the question is incomplete below is the missing part

Question:  determine the temperature, in °R, at the exit

answer:

T2= 569.62°R

Explanation:

T1 = 540°R

V2 = 600 ft/s

V1 = 60 ft/s

h1 = 129.0613  ( value gotten from Ideal gas property-air table )

<em>first step : calculate the value of h2 using the equation below </em>

assuming no work is done ( potential energy is ignored )

h2 = [ h1 + ( V2^2 - V1^2 ) / 2 ] * 1 / 32.2 * 1 / 778

∴ h2 = 136.17 Btu/Ibm

From Table A-17

we will apply interpolation
