Answer:
Technician B says that the reading is determined by where a dial points on a scale.
Explanation:
A refractometer is a devise used by scientists to gauge a liquids index of refraction.
The refractive index of a liquid is the ratio of light velocity of a specific wavelength in air to its velocity in the substance in evaluation.
The steps of reading a measurement are;
point the front of the refractometer towards the light source and view into the eyepieceYou will see the line outlined at a different point on the refractometer's internal indexRead the point on the index at which the line falls
how many robots does bailey nursery own
Answer:
The Bailey family has flourished during its business’ 110-year history. But Bailey Nurseries’ leaders still operate with the belief that the family doesn’t always know best. The company has grown from a one-man operation selling fruit trees and ornamental shrubs to one of the largest wholesale nurseries in the United States, thanks to insights from those who are family and those who aren’t.
“For a business to thrive, you have to ask for outside help,” says Terri McEnaney, president of the Newport-based company and a fourth-generation family member. “We get an outside perspective through family business programs, advisors and our board, because you can get a bit ingrained in your own way of thinking.”
When Bailey Nurseries chose its current leader in 2000, it brought in a facilitator who gathered insights from key employees, board members and owners. Third-generation leaders (and brothers) Gordie and Rod Bailey picked Rod’s daughter McEnaney, who had experience both inside and outside the company.
Explanation:
A train starts from rest at station A and accelerates at 0.6 m/s^2 for 60 s. Afterwards it travels with a constant velocity for 25 min. It then decelerates at 1.2 m/s^2 until it is brought to rest at station B. Determine the distance between the stations.
Answer:
The distance between the station A and B will be:
[tex]x_{A-B}=55.620\: km[/tex]
Explanation:
Let's find the distance that the train traveled during 60 seconds.
[tex]x_{1}=x_{0}+v_{0}t+0.5at^{2}[/tex]
We know that starts from rest (v(0)=0) and the acceleration is 0.6 m/s², so the distance will be:
[tex]x_{1}=\frac{1}{2}(0.6)(60)^{2}[/tex]
[tex]x_{1}=1080\: m[/tex]
Now, we need to find the distance after 25 min at a constant speed. To get it, we need to find the speed at the end of the first distance.
[tex]v_{1}=v_{0}+at[/tex]
[tex]v_{1}=(0.6)(60)=36\: m/s[/tex]
Then the second distance will be:
[tex]x_{2}=v_{1}*1500[/tex]
[tex]x_{2}=(36)(1500)=54000\: m[/tex]
The final distance is calculated whit the decelerate value:
[tex]v_{f}^{2}=v_{1}^{2}-2ax_{3}[/tex]
The final velocity is zero because it rests at station B. The initial velocity will be v(1).
[tex]0=36^{2}-2(1.2)x_{3}[/tex]
[tex]x_{3}=\frac{36^{2}}{2(1.2)}[/tex]
[tex]x_{3}=540\: m[/tex]
Therefore, the distance between the station A and B will be:
[tex]x_{A-B}=x_{1}+x_{2}+x_{3}[/tex]
[tex]x_{A-B}=1080+54000+540=55.620\: km[/tex]

A plane stress state (2D) of material is defined by: [σ] = [800300300−400] (MPa). Define the principal stresses σ1, σ2 using:
• Determinant Method
• Mohr’s Circle (determine also ????max)
Answer:
Explanation:
Given that:
[tex][\sigma] = \left[\begin{array}{cc}800&300\\ \\300&-400\end{array}\right] (MPa)[/tex]
[tex][\sigma] = \left[\begin{array}{cc}\sigma_{xx}&\sigma_{xy}\\ \\\sigma_{yx}&\sigma_{yy}\end{array}\right][/tex]
Using Determinant method
The principal stress is the maximum or minimum normal stress acting on any plane. For the 2D stress system, the 2-principle plane always carries zero shear stress.
For principal stress [tex]( \sigma_1, \sigma_2)[/tex]
[tex]\sigma_{1,2} = \dfrac{\sigma_x+ \sigma_y}{2} \pm \sqrt{( \dfrac{\sigma_x - \sigma_y}{2} )^2 + \sigma^2_{xy}}[/tex]
[tex]\sigma_{1} = \dfrac{800+(-400)}{2} \pm \sqrt{( \dfrac{800 -(-400)}{2} )^2 + (300)^2}[/tex]
[tex]\sigma_{1} = \dfrac{400}{2} \pm \sqrt{ (600)^2 + (300)^2}[/tex]
[tex]\sigma_{1} = 200+ 670.82 \\ \\ \sigma_{1} = 870.82 \ MPa[/tex]
[tex]\sigma_{2} = \dfrac{800+(-400)}{2} \pm \sqrt{( \dfrac{800 -(-400)}{2} )^2 + (300)^2}[/tex]
[tex]\sigma_{2} = 200- 670.82 \\ \\ \sigma_{1} = - 470.82 \ MPa[/tex]
According to Mohr's circle;
Mohr's circle is the locus provided that the position of the normal stress and the shear stress is acting on any plane.
Center = (a,0)
[tex]a = \dfrac{\sigma_{x}+\sigma_{y}}{2}[/tex]
[tex]a = \dfrac{800+(-400)}{2}[/tex]
a = 200 MPa
radius (r) = [tex]\sqrt{ (\dfrac{\sigma_{x}-\sigma_{y}}{2})^2 + \sigma^2 _{xy}}[/tex]
[tex]=\sqrt{ (\dfrac{800-(-400)}{2})^2 + (300)^2}[/tex]
[tex]=\sqrt{ (600)^2 + (300)^2}[/tex]
r = 670.82 MPa
[tex]\sigma_1 = a +r \\ \\ \sigma_1 = 200 + 670.82 \\ \\ \sigma_1 = 870.82 \ MPa[/tex]
[tex]\sigma_2 =-(r-a)[/tex] (it is negative because of the negative x-axis)
[tex]\sigma_2 =670.82 - 200 \\ \\ \sigma_1 = 470.82 \ MPa[/tex]
[tex]\tau_{max} = radius \ of \ Mohr's \ circle[/tex]
[tex]\tau_{max} = 670.82 \ MPa[/tex]
The gross weight of a two-place Piper Cherokee is 2000lb and its wing area is 160 ft^2. What is its wing loading
Answer:
[tex]W = 12.5\ lb/ft^2[/tex] --- in [tex]lb/ft^2[/tex]
[tex]W = 598.503N/m^2[/tex] --- in [tex]N/m^2[/tex]
Explanation:
Given
[tex]Weight=2000lb[/tex]
[tex]Area = 160ft^2[/tex]
Required
Determine the wing loading (W)
Wing loading is calculated using:
[tex]W = \frac{Weight}{Area}[/tex]
Substitute values for Weight and Area
[tex]W = \frac{2000lb}{160ft^2}[/tex]
[tex]W = 12.5\ lb/ft^2[/tex]
The answer can also be converted to N/m^2
[tex]1\ lb = 4.4482216153N[/tex]
[tex]1ft^2 = 0.092903m^2[/tex]
So, we have:
[tex]W = \frac{12.5 * 4.4482216153N}{0.092903m^2}[/tex]
[tex]W = \frac{55.6027701912N}{0.092903m^2}[/tex]
[tex]W = 598.503N/m^2[/tex]
Hence, the wing loading is:
[tex]W = 12.5\ lb/ft^2[/tex] --- in [tex]lb/ft^2[/tex]
[tex]W = 598.503N/m^2[/tex] --- in [tex]N/m^2[/tex]

What happens to the amperage draw of a condensing unit on a split AC system if the liquid line is restricted
Answer:
The amperage draw of the condensing unit will be low.
Explanation:
A condensing unit is made up of a compressor and condenser, while an evaporating unit is made up of an evaporator coil.
A split AC system is a type of air conditioner system that has a condensing unit which is placed separately from the evaporative coil unit. Then the two units are connected to each other via a copper tube containing refrigerants.
The liquid line connects the condenser to the evaporator, and if this liquid line is restricted, the amp consumed by the condensing unit will be low.
The displacement of a certain object is described by y(t) = 23 sin 5t, where t is measured in seconds. Compute its period and its oscillation frequency in rad/sec and in hertz
Answer:
5 rad/sec
0.796 Hz
1.256 seconds
Explanation:
Y(t) = 23sin5t ----1
Y(t) = aSin(w)t----2
w = 5 rad/sec
Then we get the Oscillation frequency from the formula below
w = 2πf
We make f to be the subject of this formula
f = w/2π
f = 5/2*3.24
f = 5/6.28
f = 0.796Hz
From the calculated frequency, we get the period = 1/f
= 1/0.796
= 1.256 seconds

Answer:
AirWaterIron AlloysExplanation:
Rust is quite simply hydrated Iron oxide because it is as a result of iron allows coming into contact with oxygen(air) and water.
The resulting reaction gives off rust as a product. The chemical reaction is:
4Fe + 3O₂ + 6H₂O → 4Fe(OH)₃.
You can see from above how rust is formed from Iron alloys, Oxygen and water.
As iron is a widely used components in the production of many things such as cars, rust presents a problem because in dissolving away iron, the object produced is compromised and this can lead to serious consequences if left unchecked.

. Assuming an n-type transistor with Vds of 1.8V and Vt of 0.7V, find the ranges of Vgs to put the transistor in cutoff, linear, and saturation regions.
Answer:
1. Cut off region: Vgs < 0.7 volts
2. Linear region: Vgs > 2.5
3. Saturation region: 0.7 < Vgs < 2.5
Explanation:
This question has provided us with these details
Vds = 1.8V
Vt = 0.7V
1. To get The cutoff region
Vgs < Vt
Such that when we put in the value, we have:
Vgs < 0.7 volts
This gives us the cut off region
2. The we get the Linear region using this formula:
Vds < Vgs - Vt
After we put in the values;
1.8V < Vgs - 0.7V
Such that
1.8V + 0.7V < Vgs
2.5V < Vgs
This is therefore the linear region of the transistor when Vgs > 2.5 volts
3. We get The saturation region using
Vgs < Vt and
Vds > Vgs - Vt
When we put in the values we have:
Vgs < 0.7V and
1.8V > Vgs - 0.7V
1.8V+0.7V > Vgs
2.5V > Vgs
Then our saturation region would be
0.7V < Vgs < 2.5 V
Prepare 250 cm3 2M NAOH: molar mass M = 40g/mol. calculate substance mass
Answer: The mass of the substance is 20 g
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n = moles of solute
[tex]V_s[/tex] = volume of solution in ml = 250 ml [tex](1cm^3=1ml)[/tex]
moles of [tex]NaOH[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{xg}{40g/mol}[/tex]
Now put all the given values in the formula of molality, we get
[tex]2=\frac{x\times 1000}{40\times 250}[/tex]
[tex]x=20g[/tex]
Therefore, the mass of the substance is 20 g

C. How the driver violates these things whenever he can.
D. How the driver appreciates all the colors he sees.
Answer:
A. How the driver understands and processes the things his or her eyes receive.
Explanation:
When driving, visual interpretation occurs in two things;
What the driver sees around him or her passively, mainly what is received by the eyeHow the driver understands and processes the things his or her eyes receiveProper vision is vital while driving. There is the central vison and the peripheral vision. The central vision is what the driver sees in front through the windshield straight ahead. The Peripheral vision is what is seen at the corners of the eyes.
In driving, visual interpretations are important as it entails what the driver sees and A. How the driver understands and processes the things his or her eyes receive.
It's important for drivers to have proper vision when driving. A driver should be able to interpret what the driver sees around him or her passively.
Also, it's important for the drive to be able to understand and processes the things his or her eyes receive. This is vital in order to prevent accidents.

Assuming an n-type transistor with Vds of 1.8V and Vt of 0.7V, find the ranges of Vgs to put the transistor in cutoff, linear, and saturation regions.
Answer:
1. Vgs<0.7
2. Vgs>2.5
3. 0.7<vgs<2.5
Explanation:
The information below was used to answer to answer this question.
Vds = 1.8V
Vt = 0.7V
1.
The cutoff region
Vgs < Vt
= Vgs < 0.7 volts
This the cut off region
2.
Linear region
Vds < Vgs - Vt
When we put in the values
1.8V < Vgs - 0.7V
1.8V+0.7V < Vgs
2.5Volts < Vgs
This is the linear region when Vgs > 2.5 volts
3.
The saturation region
Vds > Vgs - Vt
When we put in the values we have:
1.8V > Vgs - 0.7V
2.5V > Vgs
And 0.7 < Vgs
Then the saturation region is:
0.7V < Vgs < 2.5 V

6 A square silicon chip (k 150 W/m K) is of width w 5 mm on a side and of thickness t 1 mm. The chip is mounted in a substrate such that its side and back surfaces are insulated, while the front surface is exposed to a coolant. If 4 W are being dissipated in circuits mounted to the back surface of the chip, what is the steady-state temperature difference between back and front surfaces
Answer:
1.1⁰C
Explanation:
Width W = 5mm = 0.005
Thickness t = 1 mm = 0.001
K = thermal conductivity = 150W/m.K
P = q = heat transfer rate = 4W
We are to find the steady state temperature between the back and the front surface
We have to make these assumptions:
1. There is steady state conduction
2. The heat flow is of one dimension
3. The thermal conductivity is constant
4. The heat dissipation is uniform
We have:
∆t = t*P/k*W²
= (0.001m x 4W)/150x(0.005)²
= 0.004/0.00375
= 1.06667
This is approximately,
1.1⁰C
