Vs = 9 V, I = 13.6 mA. What is R?
Answer:
661.7 ohm
Explanation:
The base formula for the solution is
[tex]i = \frac{v}{r} [/tex]
so the I is equal to V divided by R and so we can change the formula according to the given stats so we change it to
[tex]r = \frac{v}{i} [/tex]
just put the stats in V and I and you will get the answer, don forget to change the milliampere to ampere!!
The status of which of these determines the sequence in which output devices, such as solenoid values and motor contactors, are turned on and off?
A: Physical inputs and outputs
B: NO contract instructions
C: Output coil instructions
The status of physical inputs and outputs determines the sequence in which output devices, such as solenoid values and motor contactors, are turned on and off. The correct option is A.
What is output device?An output device is any piece of computer hardware that transforms data into a form that can be understood by humans or, historically, into a form that can be physically read by machines and used with other non-computerized equipment.
Text, graphics, sound, touch, or video are all acceptable. The primary output component of a computer is the monitor.
An output device enables the computer to convey data in a format that is understandable to humans, such as sound played through a speaker.
The order in which output devices, such as solenoid values and motor contactors, are turned on and off depends on the status of the physical inputs and outputs.
Thus, the correct option is A.

I need to drop 10 V to feed an LED from a 12 V power supply. The resistor value is 490 Ω. How much of my battery power will be wasted in the resistor?
Answer:
P = 0.204 W
Explanation:
Given that,
Voltage drop is 10 V to feed an LED from a 12 V power supply. The resistor value is 490 Ω.
We need to find how much of my battery power will be wasted in the resistor. The power of a battery is given in terms of voltage and resistance is given by :
[tex]P=\dfrac{V^2}{R}[/tex]
V is the voltage drop to feed an LED
Putting all the values,
[tex]P=\dfrac{(10)^2}{490}\\\\P=0.204\ W[/tex]
So, 0.204 W of power will be wasted in the resistor.

Answer:
D. cutting-plane view
Explanation:
When using the cutting plane view, cutting plane lines are utilized to show a plane or planes in which a sectional view is shown. Section views give a clear indication of interior views of an object or structure including hidden parts or features which are not directly visible through convectional ways such as direct observation.

Answer:
D
Explanation: you need a jump cable to hook on a power source because the jump cable has two color cables to hook up to the power source. the two jump cables have two colors to tell you which one is positive and negative. The red one is the positive and the black on is the negative one.
The denominator of a fraction is 4 more than the numenator. If 4 is added to the numenator and 7 is added to the denominator, the value of the fraction 1 half find the original fraction.
Answer:
[tex]\frac{3}{7}[/tex]
Explanation:
Lets take the numerator of the fraction to be = x
So the denominator of the fraction is 4 more than the numerator = x+4
The fraction is ;[tex]\frac{x}{4+x}[/tex]
Now add 4 to the numerator and add 7 to the denominator as;
[tex]\frac{x+4}{4+x+7} =\frac{x+4}{x+11}[/tex]
This new fraction is equal to 1 half =1/2
write the equation as;
[tex]\frac{x+4}{x+11} =\frac{1}{2}[/tex]
perform cross-product
2(x+4 )=1( x+11 )
2x+8 = x + 11
2x-x = 11-8
x=3
The original fraction is;
[tex]\frac{x}{4+x} =\frac{3}{3+4} =\frac{3}{7}[/tex]

Annie has been designing a new pool filter for pools of over 5,000 gallons. The prototype she designed works well, but only on pools of less than 3,000 gallons. Which statement explains why Annie is not frustrated?
A. Engineers still need to design filters for smaller pools; this prototype can be distributed to other clients.
B. Engineers work in a cyclical process; she can just begin a totally new project.
C. Engineers can always take an existing idea and expand on it.
D. Engineers will not allow failures to stop them; a previous failure can be a practical solution for a new problem.
Answer:
C. Engineers can always take an existing idea and expand on it.
Explanation:
Engineers are problem solvers. When they identify a challenge, they design solutions and test the ideas using a prototype. When the prototype performs the desired output, they go ahead to implement a full design. This is to say, they take the existing idea that works in certain parameters and expand it to fit the intended solution.
Answer choices A,B, and D are true but not correct because the issue of frustration is not indicated. They are true because they explain the general form of working of engineers which is: continuing designing everyday to solve new problems, the work done by engineers has stages and processes and finally because engineers seek to give solutions, failure is not failing but a new problem that needs a new idea as a solution.
