what is the formula for finding the magnitude of a line?​

Answers

Answer 1

Answer:

Explanation:

To work with a vector, we need to be able to find its magnitude and its direction. We find its magnitude using the Pythagorean Theorem or the distance formula, and we find its direction using the inverse tangent function. Given a position vector →v=⟨a,b⟩,the magnitude is found by |v|=√a2+b2

Answer 2
The formula is

|v|=√a2+b2

someone explain classical conditioning from Ivan Pavlovym to me please???????

Answers

Answer:

Discovered by Russian physiologist Ivan Pavlov, classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.

Explanation:

The most important thing to remember is that classical conditioning involves automatic or reflexive responses, and not voluntary behavior (that's operant conditioning, and that is a different post). What does this mean? For one thing, that means that the only responses that can be elicited out of a classical conditioning paradigm are ones that rely on responses that are naturally made by the animal (or human) that is being trained. Also, it means that the response you hope to elicit must occur below the level of conscious awareness - for example, salivation, nausea, increased or decreased heartrate, pupil dilation or constriction, or even a reflexive motor response (such as recoiling from a painful stimulus). In other words, these sorts of responses are involuntary.

The basic classical conditioning procedure goes like this: a neutral stimulus is paired with an unconditional stimulus (UCS). The neutral stimulus can be anything, as long as it does not provoke any sort of response in the organism. On the other hand, the unconditional stimulus is something that reliably results in a natural response. For example, if you shine a light into a human eye, the pupil will automatically constrict (you can actually see this happen if you watch your eyes in a mirror as you turn on and off a light). Pavlov called this the "unconditional response." (UCR)

As soon as the neutral stimulus is presented with the UCS, it becomes a conditional stimulus (CS). If the CS and UCS always occur together, then the two stimuli would become associated over time. The response that was initially produced in response to the UCS would also be produced in response to the CS, even if it was presented alone. Pavlov called this the "conditional response." (CR)

To make this a bit more concrete, we'll use Pavlov's dogs as an example. Before learning took place, the dogs would reliably salivate (UCR) when given meat powder (UCS), but they gave no response to the ringing of a bell (neutral). Then Pavlov would always ring a bell just before he would present the dogs with some meat powder. Pretty soon, the dogs began to associate the sound of the bell with the impending presence of meat powder. As a result, they would begin to salivate (CR) as soon as they heard the bell (CS), even if it was not immediately followed by the meat powder (UCS). In other words, they learned that the bell was a reliable predictor of meat powder. In this way, Pavlov was able to elicit an involuntary, automatic, reflexive response to a previously neutral stimulus.

The y incision is the start?
A.Bain exam
B. Sample collection stage
C. Internal exam
D. External exam

Answers

i believe c i could be wrong
c) internal examination; Internal Examination
The internal examination starts with a large, deep, Y-shaped incision that is made from shoulder to shoulder meeting at the breast bone and extends all the way down to the pubic bone. When a woman is being examined, the Y-incision is curved around the bottom of the breasts before meeting at the breast bone.
The next step is to peel back the skin, muscle and soft tissue using a scalpel. Once this is done, the chest flap is pulled up over the face, exposing the ribcage and neck muscles.
Two cuts are made on each side of the ribcage, and then the ribcage is pulled from the skeleton after dissecting the tissue behind it with a scalpel.
With the organs exposed, a series of cuts are made that detach the larynx, esophagus, various arteries and ligaments. Next, the medical examiner severs the organs' attachment to the spinal cord as well as the attachment to the bladder and rectum. Once this is done, the entire organ set can be pulled out in one piece and dissected for further investigation.
During this dissection, the various organs are examined and weighed and tissue samples are taken. These samples take the form of "slices" that can be easily viewed under a microscope. Major blood vessels are also bisected and examined.
The examiner opens the stomach and examines and weighs the contents. This can sometimes be helpful in figuring out the time of death (more on time of death later).
The examiner will then remove the body block from the back and put it behind the neck like a pillow, raising the patient's head so that it's easier to remove the brain.
The examiner makes a cut with a scalpel from behind one ear, across the forehead, to the other ear and around. The cut is divided, and the scalp is pulled away from the skull in two flaps. The front flap goes over the patients face and the rear flap over the back of the neck.
The skull is cut with an electric saw to create a "cap" that can be pried off, exposing the brain. When the cap is pulled off, the dura (the soft tissue membrane that covers the brain) remains attached to the bottom of the skull cap. The brain is now exposed. The brain's connection to the spinal cord and tentorium (a membrane that connects and covers the cerebellum and occipital lobes of the cerebrum) are severed, and the brain is easily lifted out of the skull for examination.
Throughout this whole process, the medical examiner is looking for evidence of trauma or other indications of the cause of death. The process varies based on the nature of the case and is incredibly detailed -- the forensic pathologist has to adhere to an intricate, in-depth process to ensure the proper collection and documentation of evidence.
After the examination, the body has an open and empty chest cavity with butterflied chest flaps, the top of the skull is missing, and the skull flaps are pulled over the face and neck. To prepare the body for the funeral home:
The organs are either put back into the body or incinerated.
The chest flaps are closed and sewn back together.
The skull cap is put back in place and held there by closing and sewing the scalp.
The funeral home is then contacted to pick up the deceased.
The whole process takes careful work. Dr Kiesel explains how long this can take:
"An average autopsy case takes about four hours. That's including all the paperwork. There is about a half an hour before and after the autopsy for doing the external examination, the dictation, the paperwork. The autopsy can take anywhere from one hour to two hours if it's an uncomplicated case. If it's a complicated case like a homicide ... it can take many hours -- 4 to 6 hours."
Dr Kiesel continues, "The medical examiner will then take all of the information that they've received from the autopsy exam, all of the information they've received from the investigation, and they will determine a cause of death and a manner of death."
