We are writing a subroutine, and want to use $t0. What are the considerations? (check all that apply)
1 - We know that the routine which called us gives us permission to use this register, so we don't have to save its value before using it.
2 - The routine which called us may have an important value in that register, so we should save its value before using it.
3- We know that the subroutine won't touch the value in $t0, but if it does, it will save the value then restore it, so the value will be preserved for us.
4 - If this is a recursive subroutine, then we should save the value of $t0.
5- If we have an important value in $t0, and we are going to call another subroutine, we should save the value in $t0 before making the call, and restore the value when we get back from the subroutine.
6- Perhaps we've used $t0, but we are done with the value before calling the subroutine, so in this case we don't have to save its value.
Q2) What values should be saved to the stack? Select all that apply.
1 - The $v0 register
2- The $fp register, if the routine uses it
3- The pc register
4 - Any of the $s registers that this routine uses
5 - The $sp register
6- Any of the $t registers if this routine calls a subroutine and these register have important values
7 - The $ra register (if this routine calls a subroutine)

Mathematical induction is used to demonstrate that 4 evenly divides 3(2n) - 1 for any positive integer n: First: Base case We obtain \(3^{(2n)\) - 1 = \(3^2\) - 1 = 9 - 1 = 8 for n = 1. Since 8 may be divided by 4, the basic assumption is true.

Inductive hypothesis in step two

Assume that 4 evenly divides \(3^{(2k)\) - 1 for all positive integers k. In other words, there is a number m such that \(3^{(2k)\) - 1 = 4m.

Inductive step

We need to show that the statement holds for (k+1), that is, we need to prove that 4 evenly divides \(3^{(2(k+1))\) - 1.

\(3^{(2(k+1))} - 1 = 3^{(2k + 2)} - 1\\\\= (3^2)^k * 3^2 - 1\\\\= (9^k) * 9 - 1\\\\= (8 + 1)^k * 9 - 1\\\\= 8(8^k) * 9 - 1\\\\= 8(3^{(2k)}) * 9 - 1\\\\= 8(3^{(2k)} - 1) + 8\)

8(\(3^{(2k)\) - 1) + 8 = 8(4m) + 8 = 4(8m + 2)

By mathematical induction, we have proven that for any positive integer n, 4 evenly divides \(3^{(2n)\) - 1.

To demonstrate through mathematical induction that 6 evenly divides 7n - 1 for any positive integer n:

The strategy is the same as in section (a).

For n = 1, we have \(7^n\) - 1 = \(7^1\) - 1 = 7 - 1 = 6. Since 6 is divisible by 6, the base case holds.

Assume that for some positive integer k, 6 evenly divides \(7^k\) - 1. That is, there exists an integer m such that \(7^k\) - 1 = 6m.

We need to show that the statement holds for (k+1), that is, we need to prove that 6 evenly divides\(7^{(k+1)\) - 1.

\(7^{(k+1)} - 1 = 7^k * 7 - 1\\\\= (7^k - 1) * 7 + 6\)

\((7^k - 1) * 7 + 6 = (6m) * 7 + 6 = 6(7m + 1)\)

Thus, by mathematical induction, we have proven that for any positive integer n, 6 evenly divides \(7^n\) - 1.

Answer:

E = 8.83 kips

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

\(E = \frac{\sigma}{\epsilon}\\\\E = \frac{6.62\ kips}{7.5\ x\ 10^{-4}}\)

E = 8.83 kips

The non-linearity error as a percentage of the full-scale reading at 100 degree C  is - 0.89%.

Non-linearity error is defined as the biggest deviation from a straight line linking the output signal to the applied force, known as the "best straight," that the calibration curve makes. In order to eliminate second order nonlinearity, the sensor signal conditioning system feeds a portion of the output signal back to the sensor.

If EMF and Celsius temperature have a proportional relationship, then the recorded value of EMF at 100 °C will be understood to be a temperature of.

T/5.268 = 400/21.846

T = 5.268(400/21.846) ≈ 96.457 °C

As a percentage of the full scale, the mistake is

(96.457 -100)/400 × 100% ≈ -0.886%

The estimated flow rate of cyclohexane through the pipe is 2.62 kg/s.

The volumetric flow rate is the volume of fluid that passes per unit time in physics and engineering, particularly fluid dynamics.

To estimate the flow rate of cyclohexane through the pipe, we can use the Darcy-Weisbach equation for pressure drop in pipes:

ΔP = f x (L/D) x (ρ x \(V^2\) / 2)

V = √(2 x ΔP / (f x ρ) x (D/L))

The Reynolds number for this flow can be calculated as:

Re = (ρ x V x D) / μ

Re = (778 kg/\(m^3\) x V x 0.03 m) / 0.00114 Pa·s = 20355 x V

Now we can calculate the fluid velocity:

V = √(2 x ΔP / (f x ρ) x (D/L))

7 barg = (7 + 1) bar = 800000 Pa

The downstream pressure is 1 atm, which is equivalent to 101325 Pa.

The pressure drop is therefore:

ΔP = 800000 Pa - 101325 Pa = 698675 Pa

The fluid density is 778 kg/\(m^3\).

V = √(2 x 698675 Pa / (0.03 x 778 \(kg/m^3\) x 100 m) x (0.03 m / 100 m))

V = 5.29 m/s

Finally, we can calculate the mass flow rate (ṁ) of cyclohexane using the formula:

ṁ = ρ x A x V

A = π x \((D/2)^2\) = π x \((0.015 m)^2\) = 0.000706 \(m^2\)

ṁ = 778 kg/\(m^3\) x 0.000706 \(m^2\) x 5.29 m/s = 2.62 kg/s

Thus, the flow rate is 2.62 kg/s.

Answer:

The fat and protein contents of corn flour in dried basis are 1.213% and 6.549%, respectively. The fat and protein contents of wheat flour in dried basis are 2.041% and 14.655%, respectively.

Explanation: To convert the fat and protein contents of flour from wet basis to dry basis, we need to assume a certain moisture content to calculate the amount of dry matter in the flour. In this case, we will assume a moisture content of 0%, which means that we are calculating the fat and protein contents on a completely dry basis.

To calculate the fat and protein contents in dried basis, we can use the following formulas:

Fat (dried basis) = Fat (wet basis) / (1 - moisture content)

Protein (dried basis) = Protein (wet basis) / (1 - moisture content)

Using these formulas and the given values, we can calculate the fat and protein contents of corn flour and wheat flour in dried basis as follows:

For corn flour:

Fat (dried basis) = 1.2% / (1 - 0.12) = 1.213%

Protein (dried basis) = 6.5% / (1 - 0.12) = 6.549%

For wheat flour:

Fat (dried basis) = 2.0% / (1 - 0.14) = 2.041%

Protein (dried basis) = 14.0% / (1 - 0.14) = 14.655%

Explanation:

Modulus of elasticity = Stress/Strain

Since stress = Force/Area

Given

Force = 1000lb

Area = 0.75sqin

Stress = 1000/0.75

Stress = 1333.33lbsqin

Strain

Strain = Stress/Modulus of elasticity

Strain = 1333.33/5,000,000

Strain = 0.0002667

Also

Strain = extension/original length

extension = 0.005in

Original length = extension/strain

With increased heating due to heavy current flow, the transistor is damaged.

Answer:

the closest distance the center of gravity can be behind the front axle to have the vehicle achieve its maximum acceleration from rest on good, wet pavement is 47.8 in

Explanation:

Given that;

Weight of car W = 2600 lb

power = 80 hp = 44000 lb ft/s

Engine rpm = 3296

gear reduction ratio e = 10

drivetrain efficiency n = 95% = 0.95

wheel radius R = 16 in  = 1.3333 ft

Length of wheel base L = 95 in =

coefficient of road adhesion u = 0.60

height of center of gravity above pavement  h = 22 in

we know that;

Coefficient of rolling resistance frl = 0.01 for good wet pavement

distance of center of gravity behind the front axle lf = ?

Maximum tractive effort (Fmax) =  (uW / L) (lf - frl h) / (1 - uh / L)

First we calculate our Fmax to help us find lf

Power = Torque × 2π × Engine rpm / 60 )

44000 = Torque ( 2π×3296 / 60)

Torque = 127.5 lb ft  

so

Fmax = Torque × e × n / R

so we substitute in our values

Fmax = 127.5 × 10 × 0.95 / 1.333

Fmax = 908.66 lb

Now we input all our values into the initial formula

(Fmax) =  (uW / L) (lf - frl h) / (1 - uh / L)

908.66 =  [(0.6×2600/95) (lf - 0.01×22)] / [1 - 0.6×22) / 95]

908.66 = (16.42( lf - 0.22)) / 0.86

781.4476 = (16.42( lf - 0.22))

47.59 = lf - 0.22

lf = 47.59 + 0.22

lf = 47.8 in

Therefore the closest distance the center of gravity can be behind the front axle to have the vehicle achieve its maximum acceleration from rest on good, wet pavement is 47.8 in
