A theta wave is a type of brain wave that is associated with sleep spindles. Brain waves is defined as the regular arrangement of electrical activity that takes place in the brain. Such brain waves are associated with behaviors, thought, and emotions.

There are five types of brain waves that are ranging from lower frequency level to a higher frequency level. They are as follows delta, alpha, theta, beta, and gamma brain wave.

Further explanation:

Sleep involves the recurring state of mind or an inconsistent state of being. These phases can be differentiated from one another. Sleep is divided into two general phases, such as,

(i) Rapid eye movement (REM): This stage is an active period of sleep characterized by the intense activity of the brain.

In these stages, the waves originating from the brain are fast and desynchronized similar to those waves occurs in the waking stage.

(ii) Non-rapid eye movement (NREM): This stage is associated with the reduction in the physiological activity of the brain. This stage is further divided into three stages on the basis of patterns of brain wave.

The first stage of sleep takes place between sleep and wakefulness. It is a period in which a person can drift to sleep.

In this stage, the process of respiration and heartbeat slows down. Muscle tension and body temperature decreases during this phase.

This stage is associated with the alpha and theta waves according to their brain activity. Theta waves have low frequency and high amplitude than alpha waves.

In stage 2, the body is in a deep relaxation state, and the activity of the brain is dominated by theta wave. The activity of the mind is also interrupted by brief bursts of activity called sleep spindles.

It is defined as a quick burst of high-frequency brain waves that is essential for learning and memory.

A theta wave is a type of brain wave associated with sleep spindles.

Theta waves are involved in daydreaming and sleep and also connected to experiencing and feeling deep and raw emotions. Those waves have benefits because can help in improving our intuition and creativity.

How would an x-ray technician position the camera to produce a frontal view of a patient's abdominal cavity?

leva [86]

Answer: Option A. "In front of the patient, pointing at his navel"

Explanation:

The X-ray of abdominal cavity is known as Abdominal x-ray. It has same principle as X-ray and uses ionizing radiation to take pictures of inner parts of abdominal cavity such as intestine, stomach, liver and spleen. it is used to diagnose patients with vomiting, unexplained pain, and nausea.

While diagnosing patient's abdominal cavity, x-ray technician position the camera in front of the patient, pointing at his navel in order to produce a frontal view of abdominal cavity.

Talking about a x-ray machine, it is a compact apparatus which can be taken to the patient in a hospital bed or the emergency room. The x-ray tube connects flexible arm which further extends towards the patient and an x-ray film holder (image recording) plate is placed under the patient.

The technologist will ask the patient to take position on the x-ray table or bed and will position x-ray machine over the abdominal area of the patient, in order to take the frontal view of abdominal cavity. The patient will be asked to hold their breathe to get a clear picture. The technician will turn on the x-ray machine that allows x-ray machine to produce a small burst of radiation which passes through the abdominal area and records the frontal view of patient's abdominal cavity. As a result, soft tissue shows up in shades of gray and air appears black while bones appear white on the x-ray, through which patient can be diagnosed.

Hence, the correct option is A "In front of the patient, pointing at his navel".

Why do hevier objects fall more slowly than lighter objects

Delicious77 [7]

Actually, heavier objects fall faster. The difference is infinitesimal, but there is a tiny difference because more mass causes objects to fall faster (e.g. objects fall faster on earth than on the moon). On earth, the different rate of fall between heavier and lighter objects is negligible (because objects are tiny compared to the earth's mass), so objects of different weights fall at virtually the same rate. But not at exactly the same rate. Objects of different weights must accelerate at different rates because accel.

How does conduction differ from convection?

Free_Kalibri [48]

Answer:

Explanation:

I think the first one is correct.

The second one is half right (conduction works mostly in solids). The second part is not correct. Convection works mostly in gases.

The third one is wrong about waves. Conduction usually has direct contact of particles.

The last one is not correct. There is no visible movement of matter in conduction. The definition for convection is also incorrect.
