An automobile battery, when connected to a car radio, provides 12.5 V to the radio. When connected to a set of headlights, it pr

ovides 11.7 V to the headlights. Assume the radio can be modeled as a 6.4? resistor and the headlights can be modeled as a 0.55? resistor.Part A - vth = 12.6VPart BWhat is the Thevenin equivalent resistance for the battery?Part CWhat is the Norton equivalent current for the battery?Part DWhat is the Norton equivalent resistance for the battery?

Base on the question, and in my further computation, the possible answers would be the following and I hope you are satisfied with my answer and feel free to ask for more.

- If you want to determine the Thevenin equivalent voltage and resistance without overloading the battery, then apply some known resistance 

<span><span>RL</span><span>RL</span></span> and measure the output voltage as <span><span>VL</span><span>VL</span></span>. Measure the voltage without a load as <span><span>V<span>OC</span></span><span>V<span>OC</span></span></span>. The voltage divider equation tells us that

<span><span><span>VL</span>=<span>V<span>OC</span></span><span><span>RL</span><span><span>R<span>TH</span></span>×<span>RL</span></span></span></span><span><span>VL</span>=<span>V<span>OC</span></span><span><span>RL</span><span><span>R<span>TH</span></span>×<span>RL</span></span></span></span></span>

Solve for <span><span>R<span>TH</span></span><span>R<span>TH</span></span></span>, and you know that <span><span><span>V<span>TH</span></span>=<span>V<span>OC</span></span></span><span><span>V<span>TH</span></span>=<span>V<span>OC</span></span></span></span>.

tatuchka [14]

Answer:

C. bachelor’s degree in filmmaking

Explanation:

Because Andy wants to become a multimedia producer, the degree that would best help him achieve his goal is a bachelor's degree in filmmaking.

Multimedia has to do with both audio, video and graphics or animations because it encompasses multiple media files.

Filmmaking has to do with the various forms of making and producing films. Filmmaking has to do with multiple media (multimedia) and it would help him achieve his goal.

What are the arguments for writing efficient programs even though hardware is relatively inexpensive?
Ainat [17]

Answer: Even though the hardware is inexpensive the writing of program is not efficient through this method as proper development of program is necessary for the clear execution due to factors like:-

  • The facility of writing program even the cost of hardware is less but it is not a free facility.
  • It also has a slower processing for the execution of the program
  • The construction of the efficient program is necessary for the compilation and execution of it rather than poorly constructed program is worthless and inefficient in working.

inn [45]

Answer:

#include <iostream>

using namespace std;

 

int main () {

  // for loop execution

  int semester_fees=8000;

  int b=1;

  cout<<"there are 5 years or 10 semester fees breakdown is given below"<<endl;

  for( int a = 1; a <=5; a++ ) {

     semester_fees = semester_fees*1.03;

     cout<<"Semester fees for each of semester"<<b++<<"and"<<b++<<"is:$"<<semester_fees<<endl;

     

  }

 

  return 0;

}

Explanation:

code is in c++ language

Fees is incremented yearly and i have considered only two semester per year

A computer has 4 GB of RAM of which the operating system occupies 512 MB. The processes are all 256 MB (for simplicity) and have
Afina-wow [57]

Answer:

1-p^{14} = 0.99

p^{14}= 0.01

p =(0.01)^{1/14}= 0.720

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Explanation:

Previous concepts

Input/output operations per second (IOPS, pronounced eye-ops) "is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD)"

Solution to the problem

For this case since we have 4GB, but 512 MB are destinated to the operating system, we can begin finding the available RAM like this:

Available = 4096 MB - 512 MB = 3584 MB

Now we can find the maximum simultaneous process than can use with this:

\frac{3584 MB}{256 MB/proc}= 14 processes

And then we can find the maximum wait I/O that can be tolerated with the following formula:

1- p^{14}= rate

The expeonent for p = 14 since we got 14 simultaneous processes, and the rate for this case would be 99% or 0.99, if we solve for p we got:

1-p^{14} = 0.99

p^{14}= 0.01

p =(0.01)^{1/14}= 0.720

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %
