50 lossless wire terminating in a purely resistive load has a voltage-to-wave ratio of 3. Possible values of ZL are 150 ohms and 50/3 ohms.
To find the possible values of load resistance (ZL) that result in a voltage-to-standing wave (VSWR) of 3 in a 50-ohm lossless transmission line, we can use the following formula:
VSWR = ( 1 |Γ| ) / (1 - |Γ|)
where Γ is the reflection coefficient at the load, obtained as follows:
Γ = (ZL - 50) / (ZL 50 )
For VSWR to be 3, we can solve the above equations |Γ| = 0.5 which gives:
0.5 = |(ZL - 50) / (ZL
Squaring both sides and rearrangement gives:
ZL^2 - 50ZL - 2250 = 0
Solving this quadratic equation gives:
ZL = 25 (1 √11) or ZL = 25 (1 - √11)

How a washing machine works (from Wikipedia) All the important parts of the clothes washer are electrically controlled, including the inner drum, the valves, the pump, and the heating element. The programmer is like the conductor of an orchestra, switching these things on and off in a sensible sequence that goes something like this: 1. You put your clothes in the machine and detergent either in the machine itself or in a tray up above. 2. You set the program you want and switch on the power. 3. The programmer opens the water valves so hot and cold water enter the machine and fill up the outer and inner drums. The water usually enters at the top and trickles down through the detergent tray, washing any soap there into the machine. 4. The programmer switches off the water valves. 5. The thermostat measures the temperature of the incoming water. If it's too cold, the programmer switches on the heating element. This works just like an electric kettle or water boiler. 6. When the water is hot enough, the programmer makes the inner drum rotate back and forth, sloshing the clothes through the soapy water. 7. The detergent pulls the dirt from your clothes and traps it in the water. 8. The programmer opens a valve so the water drains from both drums. Then it switches on the pump to help empty the water away. 9. The programmer opens the water valves again so clean water enters the drums. 10. The programmer makes the inner drum rotate back and forth so the clean water rinses the clothes. It empties both drums and repeats this process several times to get rid of all the soap. 11. When the clothes are rinsed, the programmer makes the inner drum rotate at really high speed—around
80mph(130 km/h)
. The clothes are flung against the outside edge of the inner drum, but the water they contain is small enough to pass through the drum's tiny holes into the outer drum. Spinning gets your clothes dry using the same idea as a centrifuge. 12. The pump removes any remaining water from the outer drum and the wash cycle comes to an end. 13. You take your clothes out and marvel at how clean they are! 14. But there's still the problem of drying your wet clothes to figure out
The embedded computer system controls the washing machine by programming a sequence of steps that precisely control the water valves, heating element, inner drum rotation, and pump to wash and spin the clothes clean.
a) What are the inputs devices?The inputs devices for the controller of a washing machine would include the detergent tray, the power switch, the program selector, the thermostat, and the heating element.
b) What are the outputs?
The outputs for the controller of a washing machine would include the water valves, the inner drum, the pump, and the high-speed spin of the inner drum.
c) Name at least two safety features to include and specify
Two safety features that could be added to the controller for a washing machine are a temperature monitor and a motor overload protection. The temperature monitor would ensure that the water temperature does not exceed a certain threshold, while the motor overload protection would ensure that the motor does not become overloaded when running at high speeds. Both of these safety features could be implemented with software.
d) Describe a useful feature which could you add in software without requiring additional hardware.
A useful feature that could be added in software without requiring additional hardware is a timer. This timer would allow the user to set the machine to run at a certain time, allowing them to take advantage of lower electricity prices at certain times of the day.
e) Describe two useful energy-saving features which could you add in software if the controller could keep track the time of day
Two useful energy-saving features that could be added in software if the controller could keep track of the time of day are a delayed start and an off-peak washing cycle. The delayed start would allow the user to set the machine to run at a later time, allowing them to take advantage of lower electricity prices at certain times of the day. The off-peak washing cycle would allow the machine to run at a lower power setting and for a longer period of time when electricity prices are lower, resulting in energy savings.
f) Describe a useful feature which could you add in software if the machine included an internet connection
A useful feature that could be added in software if the machine included an internet connection is remote monitoring and control. This would allow the user to monitor and control the washing machine from anywhere in the world, allowing them to start and stop the machine, adjust settings, and receive notifications.

Below is the derivation of the dynamic model for a double pendulum system. Verify the derivation is correct and determine what assumptions were necessary to arrive at the given equations of motion. Then, convert the given equations to state-space form. FFFF EF,-F +From+Fre: 140, If we make a few assumptions, the equations of motion are: md, gm, +k(0,0 -0,8) 0 m.d. gm +k(d,, -0,)=0 m m 2.7 kg: d, -d-0.45 meters bib, 0.05 Nm 0.65 meters K-13 N . Gravity. -9.81 m
The assumptions necessary to arrive at the given equations of motion are that the masses of the pendulums are constant, the spring constant is also constant, and there is no friction present in the system.
What is friction?Friction is the force that resists the movement of two objects sliding against each other.
The equations of motion for a double pendulum system can be derived from the Lagrangian formulation. The Lagrangian for the system is given by:
L = T – V
Where T is the kinetic energy of the system, and V is the potential energy of the system.
The kinetic energy of the system can be expressed as:
T = 1/2 m1v12 + 1/2 m2v22 + 1/2 I1w12 + 1/2 I2w22
Where m1 and m2 are the masses of the two pendulums, v1 and v2 are their respective velocities, I1 and I2 are their respective moments of inertia, and w1 and w2 are their respective angular velocities.
The potential energy of the system can be expressed as:
V = m1gy1 + m2gy2 + 1/2 k(θ1 – θ2)2
Where g is the acceleration due to gravity, k is the spring constant, and y1 and y2 are the heights of the two pendulums.
After substituting the expressions for T and V into the Lagrangian, and then taking its variations with respect to θ1 and θ2, the equations of motion can be expressed as:
m1d2θ1/dt2 + m2d2θ2/dt2 + g(m1sinθ1 + m2sinθ2) + k(θ1 – θ2) = 0
m2d2θ1/dt2 + m2d2θ2/dt2 + g(m2sinθ1 + m2sinθ2) + k(θ1 – θ2) = 0
Assuming the masses are constant and the spring constant is also constant, the above equations can be rewritten as:
m1d2θ1/dt2 + gm1sinθ1 + k(θ1 – θ2) = 0
m2d2θ2/dt2 + gm2sinθ2 + k(θ2 – θ1) = 0
These equations can be converted to state-space form by introducing the state variables x1 = θ1, x2 = θ2, x3 = dθ1/dt, x4 = dθ2/dt. The equations can then be expressed as:
dx1/dt = x3
dx2/dt = x4
dx3/dt = -gm1sin(x1)/m1 – k(x1 – x2)/m1
dx4/dt = -gm2sin(x2)/m2 – k(x2 – x1)/m2
The assumptions necessary to arrive at the given equations of motion are that the masses of the pendulums are constant, the spring constant is also constant, and there is no friction present in the system.

? if the dissolved load is discharged into streams what will this do to the water supply, like our water here
The makeup of the dissolved compounds determines how the dissolved load affects the water supply. While certain dissolved compounds can have positive effects on water quality, others can have harmful ones.
How does dissolved load behave in a stream?Due to the fact that on steeper surfaces, rain is less likely to enter the rocks, leading to less chemical weathering, which lowers the dissolved load, the contribution of the dissolved load to the overall stream load reduces as topographic relief increases.
How does stream capacity change as a result of discharge?Stream capacity is the greatest weight that a stream is capable of carrying. With increasing discharge, competence and capacity both rise. At high discharge, material with the size of boulders and cobbles can flow with the stream and is consequently carried.
