Which of the forces applied to the block perform nonconservative work on the system? Check all that apply. - normal force - weight of the block - applied force - spring force - friction Learning Goal: To use the conservation of energy with nonconservative forces to determine the maximum height and velocity for a block moving on a ramp.
The block shown in slides on the ramp and is attached to the spring. At the starting point, the spring is not stretched or compressed and the block has a velocity up the ramp of vi = 3.7 m/s. A force F = 230 N is also applied to the block, parallel to the ramp. The coefficient of friction between the block and the ramp is μk = 0.25, the spring constant is k = 600 N/m, the mass of the block is m = 7 kg, and the angle of the ramp is θ = 33° Use the conservation of energy Ti +V1 + (ΣU1-2) noncons = T2 + V2
Answers
The forces applied to the block that perform nonconservative work on the system are: Applied force friction
Friction is a force that resists the motion between two surfaces that are in contact.. Nonconservative forces are forces that dissipate the mechanical energy of a system. The forces that perform nonconservative work are the applied force and the frictional force.
The normal force and the spring force are conservative forces because they do not dissipate mechanical energy but rather conserve it. They do not perform nonconservative work.
Friction can both be beneficial and harmful. For example, it can be useful for preventing slipping and sliding of objects.

What is the difference between an end moraine and a ground moraine, and how do they relate to the budget of a glacier?
Answers
The end moraine is a ridge till forming at the end of the glacier when the ice record is in equilibrium. The ground moraine is a layer of till that is deposited when the ice melts when the ice shear exceeds the accumulation. End moraine is a type of moraine that forms at the end (edge) of a glacier, marking its maximum stride.
What is moraine?A moraine is an accumulation of unconsolidated debris (regolith and rocks), sometimes referred to as glaciation, that occurs in current and former glacial regions, and has previously been covered by glaciers or ice caps. drift ice. It can consist of partially round particles ranging in size from boulders (in this case often called boulder clay) to gravel and sand, in a subdivided mass of clay material sometimes called ice powder. Lateral moraines are mounds that form on the side of the glacial flow, and end glacials that form at the foot, marking the maximum advance of the glacier. Other types of moraines include ground moraines (areas that are covered until the formation of plates over flat or irregular terrain) and intermediate moraines (the morass formed at the encounter) of two glaciers).

use the superposition principle to solve for va in the circuit
Answers
The superposition principle allows us to solve for va in a circuit with multiple sources by finding the individual contributions of each source and adding them up. This can be done by turning off one source at a time and solving for va in each case.
To solve for va in the circuit using the superposition principle, we first need to find the contributions of each source individually and then add them up. We can turn off one source at a time and solve for va in each case. Then we add up the individual contributions to get the final value of va.
For example, if we turn off the voltage source V1, we can redraw the circuit with V2 and the current source as the only active sources. We can then solve for va using Ohm's law and Kirchhoff's laws. We repeat the same process for V2 and the current source, each time turning off the other sources.
After finding the individual contributions, we can add them up to get the final value of va using the principle of superposition. The final value of va will be the algebraic sum of the individual values.

The gross weight of a two-place Piper Cherokee is 2000lb and its wing area is 160 ft^2. What is its wing loading
Answers
Answer:
\(W = 12.5\ lb/ft^2\) --- in \(lb/ft^2\)
\(W = 598.503N/m^2\) --- in \(N/m^2\)
Explanation:
Given
\(Weight=2000lb\)
\(Area = 160ft^2\)
Required
Determine the wing loading (W)
Wing loading is calculated using:
\(W = \frac{Weight}{Area}\)
Substitute values for Weight and Area
\(W = \frac{2000lb}{160ft^2}\)
\(W = 12.5\ lb/ft^2\)
The answer can also be converted to N/m^2
\(1\ lb = 4.4482216153N\)
\(1ft^2 = 0.092903m^2\)
So, we have:
\(W = \frac{12.5 * 4.4482216153N}{0.092903m^2}\)
\(W = \frac{55.6027701912N}{0.092903m^2}\)
\(W = 598.503N/m^2\)
Hence, the wing loading is:
\(W = 12.5\ lb/ft^2\) --- in \(lb/ft^2\)
\(W = 598.503N/m^2\) --- in \(N/m^2\)

Required:
a)Determine the power output of the turbine, in hp.
b) The Flow rate
Answer:
a) \(w=74.26hp\)
b) \(m=0.22\)
Explanation:
From the question we are told that:
Initial Pressure \(p_1= 145 psi\)
Initial Temperature \(T_1 =2700oR=>2240.33^oF\)
Final Pressure \(p_2= 29 psi\)
Final Temperature \(t_2=1974oR=>1514.33^oF\)
Output Power \(w=74.26hp\)
Heat transfer Rate \(Q=14BTU/s\)
Generally the equation for Steady flow energy is mathematically given by
\(Q-w=m(h_2-h_1)\)
Where
\(m=Flow\ rate\)
From Steam table
\(h_1=704btu/ib (at\ p_1= 145\ psi,\ T_1 =2700oR=>2240.33^oF )\)
\(h_2=401btu/ib (at\ p_2= 29psi\ t_2=1974oR=>1514.33^oF )\)
Therefore
\(-14-74.26=m(401-704)\)
\(m=\frac{-14-74.26}{(401-704)}\)
\(m=0.22\)

(t)=u(t) as state variables, r(t) as input, and y(t) as output. Show the derivation of the state-space model equations as well as the final state-space model. What are the matrices A,B,C, and D ?
Answers
To derive the state-space model for the given closed-loop system, let's start by writing the differential equations for the plant and the controller:
Plant:
The plant equation is given as:
y˙(t) + y(t) = 2u(t)
Controller:
The controller equation is given as:
u˙(t) + u(t) = 3r(t)
To define the state variables, let's set x1(t) = e(t) and x2(t) = u(t). Now, we need to express the differential equations in terms of the state variables.
Plant:
Differentiating x1(t) = e(t), we get:
x˙1(t) = e˙(t)
Since e(t) = y(t) - r(t), we can rewrite the equation as:
x˙1(t) = y˙(t) - r˙(t)
Using the plant equation, we substitute the value of y˙(t) into the above equation:
x˙1(t) = -y(t) + 2u(t) - r˙(t)
Controller:
Differentiating x2(t) = u(t), we get:
x˙2(t) = u˙(t)
Using the controller equation, we substitute the value of u˙(t) into the above equation:
x˙2(t) = 3r(t) - u(t)
Now, we can express the above differential equations in matrix form:
[x˙1(t)] [ 0 -1 ] [x1(t)] [ 0 ] [x2(t)]
[x˙2(t)] = [ 0 -1 ] [x2(t)] + [ 3 ] [r(t) ]
The matrices A, B, C, and D for the state-space model are:
A = [ 0 -1 ]
[ 0 -1 ]
B = [ 0 ]
[ 3 ]
C = [ 1 0 ]
D = 0
In summary, the state-space model for the given closed-loop system is:
[x˙1(t)] [ 0 -1 ] [x1(t)] [ 0 ] [x2(t)]
[x˙2(t)] = [ 0 -1 ] [x2(t)] + [ 3 ] [r(t) ]
With the matrices A, B, C, and D defined as mentioned above.
This state-space model can be used to analyze and design the closed-loop system. It provides a concise representation of the system dynamics and facilitates control design and analysis.

Answers
Control charts for variables are based on data that come from continuous measurement processes.
These processes generate numerical measurements of a characteristic of interest, called a variable. The variable can be any measurable attribute such as weight, length, height, volume, temperature, pressure, and so on. The data obtained from measuring the variable is plotted on a control chart to monitor the stability and performance of the process over time.
Variables control charts consist of two types: X-bar and R charts. The X-bar chart displays the average value of the variable, and the R chart displays the range or variation of the variable. Both charts are used together to detect any shifts or changes in the process mean or variability.
The data used to construct the control charts should be representative of the process being monitored and should be collected in a systematic and consistent manner. The data should be accurate, precise, and unbiased. Typically, a minimum of 20 to 25 consecutive samples of the variable is collected before constructing the control charts.
In summary, control charts for variables are based on data that come from continuous measurement processes of a measurable attribute. The data is used to construct X-bar and R charts to monitor the stability and performance of the process over time. The quality of the data is essential to ensure the reliability and usefulness of the control charts.

When an electric current flows through a wire with resistance, energy is liberated as heat.
Thus, when a current flows through the resistor, the electrical energy is converted into heat energy. Hence the heat that is generated in the components of the circuit possesses some resistance and is dissipated into the air around the components.
Resistance in a wire causes a hindrance to the flow of electrons, which results in the conversion of electrical energy into thermal energy. This thermal energy is then dissipated into the surrounding environment, which can be felt as heat.

For more than 35 years, there has been an entity relationship (ER) data model. Because it is rather abstract and simple to describe and explain, it is a good fit for data modelling for usage with databases. Relationship models may be easily converted to relations. ER diagrams serve as a visual representation of ER models, also known as ER schemas. The foundation of the database is comprised on autonomous objects, often known as kernels. They serve as the foundation for additional tables. The meaning of dependent entities, also known as derived entities, is derived from other tables. Additional details about one table are provided by characteristic entities. Each attribute has a name, a domain of allowed values, and an association with an entity.

For this situation: (a)What output voltage results? (b)What is the voltage gain from source to load? (c)What is the voltage gain from the amplifier input to the load? (d)If the output voltage across the load is twice that needed and there are signs of amplifier saturation, suggest the location and value of a single resistor that would produce the desired output. Choose an arrangement that would cause minimum disruption to an operating circuit. (Hint)
Answers
Answer:
a) 2.40 V
b) 120
c) 150
d) 8 kΩ in parallel with the amplifier input
Explanation:
The voltage divider between the source resistance and the amplifier input resistance makes the amplifier input voltage be ...
vi = (10 mV)(ri/(rs+ri)) = (10 mV)(40/(10+40)) = 8 mV
(a) The gain of 300 makes the open-circuit amplifier output voltage be ...
Vo = 300(8 mV) = 2400 mV = 2.40 V . . . . open-circuit output voltage
__
(b) The load voltage is the result of voltage-divider action between the output resistance and the load resistance.
Vl = Vo(rl)/(ro +rl) = 2.40 V(100)/(100 +100) = 1.20 V
So, the overall voltage gain from the source is ...
vl/vs = (1.20 V)/(0.010 V) = 120 . . . . voltage gain from source
__
(c) The voltage gain to the load from the amplifier input is ...
vl/vi = 1.200 V/0.008 V = 150 . . . . voltage gain from input to load
__
(d) To reduce the input of the amplifier without breaking the circuit, we could add a resistor in parallel with the amplifier input. It would need to reduce the gain of that voltage divider from 0.8 to 0.4 to cut the output voltage in half. That is, for some parallel resistor R (in kOhms), we want ...
R(Ri)/(R·(Ri +Rs) +Ri·Rs)) = 0.40
40R/(50R + 400) = 2/5
200R = 100R +800 . . . . cross multiply
100R = 800 . . . . . . . . . . . subtract 100R
R = 8 . . . . kOhms
Putting 8 kOhms in parallel with the amplifier input will reduce the overall gain by the required amount.

An insulated cover is placed on the tank. The tank is adiabatic. Estimate the equilibrium temperature of the system (block + water). Be sure to state all applicable assumptions.
Answers
Answer:
final temperature = 26.5°
Explanation:
Initial volume of water is 1 x 1 x 1 = 1 \(m^{3}\)
Initial temperature of water = 20° C
Density of water = 1000 kg/\(m^{3}\)
volume of copper block = 0.46 x 0.46 x 0.46 = 0.097 \(m^{3}\)
Initial temperature of copper block = 100° C
Density of copper = 8960 kg/\(m^{3}\)
Final volume of water = 1 - 0.097 = 0.903 \(m^{3}\)
Assumptions:
since tank is adiabatic, there's no heat gain or loss through the wallsthe tank is perfectly full, leaving no room for cooling airtotal heat energy within the tank will be the summation of the heat energy of the copper and the water remaining in the tank.mass of water remaining in the tank will be density x volume = 1000 x 0.903 = 903 kg
specific heat capacity of water c = 4186 J/K-kg
heat content of water left Hw = mcT = 903 x 4186 x 20 = 75.59 Mega-joules
mass of copper will be density x volume = 8960 x 0.097 = 869.12 kg
specific heat capacity of copper is 385 J/K-kg
heat content of copper Hc = mcT = 869.12 x 385 x 100 = 33.46 Mega-joules
total heat in the system = 75.59 + 33.46 = 109.05 Mega-joules
this heat will be distributed in the entire system
heat energy of water within the system = mcT
where T is the final temperature
= 903 x 4186 x T = 3779958T
for copper, heat will be
mcT = 869.12 x 385 = 334611.2T
these component heats will sum up to the final heat of the system, i.e
3779958T + 334611.2T = 109.05 x \(10^{6}\)
4114569.2T = 109.05 x \(10^{6}\)
final temperature T = (109.05 x \(10^{6}\))/4114569.2 = 26.5°

Explanation:
Two long pipes convey water between two reservoirs whose water surfaces are at different elevations. One pipe has a diameter twice that of the other; both pipes have the same length and the same value of f. If minor losses are neglected, what is the ratio of the flow rates through the two pipes?
Answers
Answer:
1 : 5.66 ≈ 1 : 6
Explanation:
Determine the ratio of the flow rates through the two pipes
The flow from the bigger pipe is 5.66 times greater than that from the smaller pipe hence the ratio of the flow rates is : 1 : 5.66

What is the basic requirement of measurements?
Answers
The basic requirement of measurements is to have a standard or reference point against which to compare the quantity being measured. This standard or reference point should be well-defined and stable, and the measurement process should be repeatable and consistent. Additionally, it is important to ensure that the measurement equipment is calibrated and in good working condition.
Answer:
The most basic requirement for measurements is the presence of a standard or reference point against which the quantity being measured can be compared. The measurement process should be repeatable and consistent, and the standard or reference point should be well-defined and stable. Furthermore, ensure that the measurement equipment is calibrated and in good working order.

compare and contrast a software development process with the software project management (poma) process.
Answers
Below you can find the compare and contrast of software development process with the software project management (poma) process.
process for developing software
A framework put on the creation of a software product is the software development process or life cycle. Such processes include a number of models, each of which describes methods for a range of tasks or activities that take place during the process. Process approaches are being used by more and more firms that build software.
Analysis of Requirements
The first step in building desired software is to identify its needs. Customers likely think they know what the product is supposed to perform, but identifying incomplete, confusing, or conflicting requirements may take ability and experience in software engineering.
method for managing software projects
The art and science of organising and supervising software projects are known as software project management. It is a branch of project management where software projects are planned, carried out, tracked, and managed. The different operations that make up software project management include project planning, determining the scope of the software product, cost estimating in various forms, task and event scheduling, and resource management.
Project Management
Scope Control
Task Estimation
Project Management
Planning the software project is a step that must be taken before the programme is actually produced. It is there to support software creation, but it doesn't really entail any specific tasks that are directly related to it; rather, it consists of a number of procedures that make software production easier.
