What is the Doppler Effect? How can the Doppler Effect be useful for a forensic investigation involving a shooting?

Answers

Answer 1
The Doppler effect is an increase (or decrease) in frequency of sound, light, or other waves as the source and observer move toward (or away from each other).
They use this is forensic investigation involving a shooting because witnesses can identify the type of firearm and the noise. 
Answer 2

Final answer:

The Doppler effect is the change in frequency or wavelength of waves, such as sound or light, as observed by someone moving relative to the source. Forensic investigations can help determine the direction and speed of a shooter in a shooting event by analyzing audio recordings.

Explanation:

The Doppler effect refers to the change in frequency or wavelength of waves to an observer who is moving relative to the wave source. It occurs with all types of waves, including sound, light, and water waves. The effect is commonly experienced when an ambulance passes by with its siren blaring; the siren's pitch appears to decrease as the ambulance moves away. This is due to the sound waves being 'stretched' out, leading to a lower frequency and hence a lower pitch.

Applications in Forensic Investigations:

In forensic investigations, the Doppler effect can be particularly useful in analyzing audio recordings of shootings. By examining the change in frequency of the gunshot sounds, experts can determine the direction and speed of the shooter or the vehicle from which the shots were fired. This can be vital in reconstructing the sequence of events and establishing the positions of the shooter and the victim(s) at the time of the incident.

Using the Doppler effect, forensic teams can also establish whether a recording is authentic or if it has been manipulated since the characteristics of the Doppler shift must conform to the laws of physics and the known movements at the scene of the crime.

Can't expand stack segment by 8 bytes to 524288 bytes.

Answers

try to clear your cashe its possible on a good computer but on a old its not possible for that hardware

Final answer:

The message “Can’t expand stack segment by 8 bytes to 524288 bytes” suggests a stack overflow issue in a program that has reached the maximum size limit for the stack memory allocated by the operating system.

Explanation:

In the context of programming and software development, encountering an error message such as “Can’t expand stack segment by 8 bytes to 524288 bytes” usually indicates that the program is attempting to use more stack memory than is allowed. The stack is a region of memory used for the temporary storage of variables, return addresses, and for managing function calls. This type of error is often termed a stack overflow, which occurs when there is an attempt to push more onto the stack than it can handle. This could be due to excessive or infinite recursion, allocating too much space for variables on the stack, or a lack of proper memory management in the code. To resolve this issue, a programmer would need to review the code for functions that may be using excessive stack space, and modify the code to use the stack more efficiently or allocate memory on the heap instead.

It will always take at least seven years to rebuild bad credit into good credit

Answers

Answer:

false

Explanation:

False. The time it takes to rebuild bad credit into good credit can vary widely and is not fixed at seven years.

The common belief that it takes seven years often stems from the fact that negative information, such as late payments or bankruptcies, may stay on a credit report for seven years. However, individuals can take proactive steps to improve their credit score before this time frame.

Rebuilding credit involves actions such as making on-time payments, reducing debt, and establishing a positive credit history. With responsible financial habits, some individuals may see improvements in their credit score within a shorter time frame than seven years.

It's important to note that the exact time needed to rebuild credit can depend on various factors, including the severity of the credit issues and the individual's efforts to address them. Working with credit counseling services and financial advisors can provide tailored guidance in the credit rebuilding process.

The salesperson in a cell phone store is telling me that the phone I'm considering has 8GB of memory, which means I can save 10,000 photos taken with the phone's camera! Is the salesperson telling me the truth? Why or why not?

Answers

The sale person is not telling you the truth. 
This is because, the size of an average picture on phone is about 3 megabytes. One gigabyte is equivalent to 1000 megabytes; so 8GB is equivalent to 8,000MB [Megabytes].
 If you divide 8,000MB by 3MB, which is the size of an average picture, you will have approximately 2,666 pictures. This means, you will only be able to store about 2,666 pictures on that phone compared to the 10,000 pictures the sale person is talking about.

Explanation: it was correct on edg

Given : an int variable k, an int array currentmembers that has been declared and initialized , an int variable nmembers that contains the number of elements in the array , an int variable memberid that has been initialized , and a bool variable isamember, write code that assigns true to isamember if the value of memberid can be found in currentmembers, and that assigns false to isamember otherwise. use only k, currentmembers, nmembers, and isamember.

Answers

Final answer:

To check if the value of memberid exists in the currentmembers array, you can use a loop to compare each element with memberid and assign true to isamember if a match is found.

Explanation:

One way to check if the value of memberid can be found in currentmembers array is by using a loop. You can iterate through each element in the array and compare it with the value of memberid. If a match is found, you can assign true to isamember and break out of the loop. Otherwise, after the loop ends, you can assign false to isamember.

bool isamember = false;
for (int i = 0; i < nmembers; i++) {
   if (currentmembers[i] == memberid) {
       isamember = true;
       break;
   }
}

In this code, we are using a for loop to iterate from the first index (0) to the last index (nmembers - 1) of the currentmembers array. We check if the value at each index is equal to memberid, and if so, we assign true to isamember and break out of the loop.
