If you were translating an if..else statement from pseudocode to ARM assembly language, and the logical operato used in the if was ==, which branch would you use following the CMP instruction? BEQ O BLO 0 BGE OBNE 0 None of the above. If you were translating an if..else statement from pseudocode to ARM assembly language, and the logical operator used in the if is >, which branch would you use following the CMP instruction? BNE O BEQ BLO O BLS BHS Assume that RO contains the hexadecimal value 20000000. If you want to store the 32 bit value in R5 at the address 20000008, without changing the value in RO, which instruction would you use? STR R5, [RO] O STR [RO], R5 STR RO, [R5, #8] O MOV [RO], R5, #4 None of the above.

Answers

Answer 1

For the first question (if logical operator is ==), the branch instruction to use following the CMP instruction would be BEQ (Branch Equal). This branch is taken if the previous comparison result was equal, indicating that the condition in the if statement is true.

For the second question (if logical operator is >), the branch instruction to use following the CMP instruction would be BGT (Branch Greater Than). This branch is taken if the previous comparison result indicated that the value in the source register is greater than the value in the destination register.

To store a 32-bit value in R5 at the address 20000008 without changing the value in RO, the instruction to use would be STR R5, [RO, #8]. This instruction stores the value in R5 into the memory address formed by adding the offset 8 to the value in RO.

For the first question, when comparing two values using the equality operator (==), the CMP instruction in ARM assembly sets the appropriate condition flags based on the result of the comparison. If the values are equal, the zero flag (Z) is set. The BEQ (Branch Equal) instruction checks the zero flag and branches to the specified label if the values are equal. Therefore, if the condition in the if statement is true (values are equal), the BEQ branch is taken.

For the second question, when comparing two values using the greater than operator (>), the CMP instruction sets the appropriate condition flags based on the result of the comparison. If the source value is greater than the destination value, the carry flag (C) is set. The BGT (Branch Greater Than) instruction checks the carry flag and branches to the specified label if the source value is greater. Thus, if the condition in the if statement is true (source value is greater), the BGT branch is taken.

To store a 32-bit value in R5 at the address 20000008 without changing the value in RO, the STR R5, [RO, #8] instruction is used. This instruction uses the base register RO and adds an offset of 8 to it, specifying the memory address where the value in R5 will be stored. This instruction does not modify the value in RO; it only uses it as a base address for the memory operation.

use superposition to find i2. give each sources contribution to i2. give answers to nearest decimal.

Answers

The contribution of voltage source (V1) to i2 is 6.67 V / 30 kΩ ≈ 0.000222 A, and the contribution of current source (I1) to i2 is 0.125 A.

To find i2 using superposition theorem, each independent source (i.e., voltage or current sources) is considered individually while keeping all other sources inactive. After that, all of the solutions are summed up to get the final solution. Here are the steps to solve this problem:

Step 1: Turn off the current source, and find the voltage at node 2 with respect to ground using only the voltage source (V1).To find the voltage at node 2, apply voltage divider rule:

V_2 = {10}/{(10+20)kΩ} * 20kΩ = 6.67 V

Step 2: Turn off the voltage source, and find the current flowing through the 20 kΩ resistor due to the current source.To find the current through the 20 kΩ resistor, we first need to calculate the Thevenin resistance (R_th) between nodes 1 and 2.

To do that, we remove the 20 kΩ resistor and short the voltage source V1. Then we have the following circuit:Here, R_th = 10 kΩ || 30 kΩ = 7.5 kΩ

Now, we calculate the Thevenin voltage (Vth) between nodes 1 and 2. This can be done by applying voltage divider rule as follows:

V{th} = 10 ,V * {30kΩ}/{10kΩ+30kΩ} = 7.5,V

Next, we add the 20 kΩ resistor back in the circuit and calculate the current flowing through it due to the current source: I = (10-7.5) V / 20 kΩ = 0.125 A

Step 3: Sum up the solutions obtained from Steps 1 and 2 to find i2.

i2 = 6.67 V / 30 kΩ + 0.125 A = 0.00039167 A ≈ 0.0004 A

(a) Since the flow is assumed to be uniform, the Velocity component is in y direction (the component) So that u = V = 0. It follows the continuity equation that dv/dy = 0 and for steady flow dv/dt = 0 so that V = v(x) under these conditions the Navier stokes equations for

0 = -ρg + μ d²v/dx²

or,  d²v/dx² = γ / μ    [γ = ρg]

Integrating the above equation,  

∫d²v/dx² = ∫γ / μ

dv/dx = γ / μ  x +c1

Because there is little air drag on the film. The Shearing stress at the free surface (or any interior parallel surface) is designed as Zxy, where

Zxy = μ dv/dx

c) If Zxy = 0 at x = h

Then 0 = γh/μ + C1

C1 = - γh / μ

Now integrating equation gives the velocity distribution in the film as

v = γ x² / 2μ - γh/μ + C2

At the belt (x=0) the fluid velocity must match the belt velocity Ve so that

V0 = 0-0+C2

C2 = V0

and the velocity  distribution is therefore

v = γ x² / 2μ - γh/μ + V0

with the velocity distribution knowm we can determine the flowrate per unit width q from the relationship

q = ∫ Vdx = ∫ γ x² / 2μ - γh/μ + V0 dx

and thus q = V0 h - γh³/3μ

The average velocity V (where, Q = Vh ) is

Vh = V0h - γh³/3μ

a differentiator has a break frequency of 100 khz and a unity gain frequency of 10 khz. over what frequency range would the circuit provide the derivative of a function and increase the signal?

Answers

     An op amp-based circuit known as a differentiator produces an output signal that is proportional to the differentiation of the input signal. In essence, an op amp differentiator is an inverting amplifier with an appropriate capacitor at its input end.

A differentiator circuit: what is it?

        Depending on the circuit time constant and the amplifier's bandwidth, the differentiator circuit produces the derivative of the input signal over a range of frequencies. Applying the input signal to the inverting input causes the output to be polarity-inverted with respect to the input signal.

       Why is a differentiator opamp used? The major application of this op-amp is to boost weak signal levels. Depending on the components used in the design, an op-amp differentiator can be either active or passive. We will utilize this differentiator amplifier in frequency modulators and wave shaping circuits because it essentially functions as a high pass filter.

      Why do op-amps utilize capacitors? A feedback capacitor is used in a typical op-amp circuit to restrict bandwidth. A feedback capacitor is a typical approach to minimize noise because restricting op-amp bandwidth will do so. Consider that a capacitor functions as a short to "high frequency" AC impulses in order to comprehend how the feedback capacitor operates.

Answer:

The volume percent of graphite is 9.9%

Explanation:

Given;

weight percent of graphite, C = 3.1wt%

density of ferrite, \(\rho _f\) = 7.9 g/cm³

density of graphite, \(\rho _g\) = 2.3 g/cm³

Determine the mass fraction;

\(W_f = \frac{C_g - C_0}{C_g -C_f} \\\\W_f =\frac{100 - 3.1}{100-0}\\\\W_f = 0.969\\\\\\W_g = \frac{C_0 - C_a}{C_g -C_f} \\\\W_g =\frac{3.1-0}{100-0}\\\\W_g = 0.031\)

Determine the volume fraction;

\(V = \frac{W_g/ \rho_g}{W_f / \rho_f \ + \ W_g / \rho_g} *100 \%\\\\V = \frac{0.031/ 2.3}{0.969 / 7.9 \ + 0.031 / 2.3}*100\%\\\\V = 9.9\%\)

Therefore, the volume percent of graphite is 9.9%

  = 4250 ( 44 x 10⁻³ )  / 3.141593 ( 5.6 x 10⁻³ ) ³

  = 4250 (44 x 1 /1000 )) / 3.141593 ( 5.6 x 10⁻³ ) ³

  = 4250 ( 11 / 250  ) / 3.141593 ( 5.6 x 10⁻³ ) ³

  = 187 / 3.141593 ( 5.6 x 1 / 1000 ) ³

  = 187 / 3.141593 (0.0056)³

  = 338943767.745358

  = 338.943768 x 10⁶

σ = 338 x 10⁶ N/m²

Now we compute the load i.e. F from the following formula:

\(F_{f}\) = 2 σ\(_{fs}\) d³/3 L

F = 2σd³/3L

  = 2(338 x 10⁶)(12 x 10⁻³)³ / 3(44 x 10⁻³)

  = 2 ( 338 x 1000000 ) ( 12 x 10⁻³)³ / 3 ( 44 x 10⁻³)

  = 2 ( 338000000 ) ( 12 x 10⁻³)³ / 3 ( 44 x 10⁻³)

  = 676000000 ( 12 x 10⁻³)³ / 3 ( 44 x 10⁻³)

  = 676000000 ( 12  x  1/1000  )³ / 3 ( 44 x 10⁻³)

  = 676000000 (  3  / 250  )³ / 3 ( 44 x 10⁻³)

  = 676000000 (  27  / 15625000 )  / 3 ( 44 x 10⁻³)

  = 146016  / 125 / 3 ( 44 x 1 / 1000  )

  = ( 146016  / 125 ) /  (3 ( 11 /  250 ))

  =  97344  / 11

F =  8849 N

If the constant is added to every observation of data then arithmatic mean obtained is

Answers

Answer:

Explanation:

Increased by the constant. Take a very simple case.

4  +  5 +  6 = 15

The mean is 5  (obtained by dividing the total (15) by the number of terms (3).

Now add a constant say 6

4 + 6 = 10

5 + 6 = 11

6 + 6 = 12

Total = 33/3 = 11

So the mean 5 is increased by the constant 6.

Now do the same thing more symbolically.

4 + c

5 + c

6 + c

Total = 15 + 3c

Divide by 3 you get 5 + c

system of many millions or even billions of stars and galactic formations moving together with a gravitational relationship

Answers

The description for a star cluster is a system of stars held together by gravity that can number from a thousand up to a million stars. The correct option is b.

What is a star cluster?

Due to their location on the dusty spiral arms on the plane of spiral galaxies, they are occasionally referred to as galactic clusters. All of the stars in an open cluster originated from the same initial massive molecular cloud.

The most basic theory states that star cluster when a massive cloud of gas and dust condenses. Once the cloud's center has attracted enough material from its surroundings, star formation can begin.

Therefore, the correct option is b, a system of stars held together by gravity that can number from a thousand up to a million stars.
