Electricity is a from of energy that when in motion exhibits magnetic, chemical and ? effects.
- A.
Lighting
- B.
Thermal
- C.
Ionic
- D.
Compound
Correct Answer
B. ThermalExplanation
Electricity, when in motion, exhibits magnetic, chemical, and thermal effects. This means that it can generate heat or be converted into heat energy. Thermal energy is a form of energy that is associated with the motion of particles within a substance. When an electric current flows through a conductor, it can produce heat due to resistance in the material. Therefore, the correct answer is thermal.Rate this question:

An conductor is any substance that easily transmits electricity. which one is a good conductor.
- A.
Concrete
- B.
Metals
- C.
Mountain rocks
- D.
Wooden fence poles
Correct Answer
B. MetalsExplanation
Metals are good conductors of electricity because they have a high number of free electrons that can easily move through the material when an electric current is applied. This allows the electricity to flow easily without much resistance. In contrast, concrete, mountain rocks, and wooden fence poles do not have a high number of free electrons and therefore do not conduct electricity as well as metals.Rate this question:

The positive electrode of electrotherapy devices is called
- A.
Galvanic
- B.
Anode
- C.
Cathode
- D.
Cataphoresis
Correct Answer
B. AnodeExplanation
The positive electrode of electrotherapy devices is called the anode. In electrotherapy, the anode is the electrode through which the positive current flows into the body. It is responsible for attracting negatively charged ions and promoting various therapeutic effects such as pain relief and tissue healing. The anode is commonly used in galvanic electrotherapy, where direct current is applied to the body for therapeutic purposes.Rate this question:

The process of forcing liquids into the tissues from the negative toward the positive pole is called
- A.
Desincrustation
- B.
Iontophoresis
- C.
Cataphoresis
- D.
Anaphoresis
Correct Answer
D. AnaphoresisExplanation
Anaphoresis is the process of forcing liquids into the tissues from the negative toward the positive pole. It is a technique commonly used in electrotherapy, where an electrical current is applied to the body to deliver medication or other substances into the tissues. This process can be used to treat various conditions, such as inflammation, pain, and muscle spasms. Unlike desincrustation, iontophoresis, and cataphoresis, which involve the movement of substances in the opposite direction, anaphoresis specifically refers to the movement of liquids from the negative to the positive pole.Rate this question:

The process of introducing water soluable products into the skin with the use of electric current is called
- A.
Iontophoresis
- B.
Cataphoresis
- C.
Anaphoresis
- D.
Desincrustation
Correct Answer
A. IontophoresisExplanation
Iontophoresis is the correct answer because it refers to the process of introducing water-soluble products into the skin using electric current. This technique is commonly used in skincare treatments to enhance the absorption of certain substances into the skin, such as medications or serums. By applying a low-level electric current, iontophoresis helps to push the products deeper into the skin, allowing for better penetration and effectiveness.Rate this question:

Forces acidic substances into deeper tissues using galvanic current from the positive toward the negative pole.
- A.
Desincrustation
- B.
Anaphoresis
- C.
Cataphoresis
- D.
Iontophoresis
Correct Answer
C. CataphoresisExplanation
Cataphoresis is a process that uses galvanic current to force acidic substances into deeper tissues. The positive pole is used to attract the acidic substances and push them towards the negative pole. This technique is commonly used in skincare treatments to deliver beneficial ingredients deep into the skin, helping to improve its condition and appearance.Rate this question:

Tesla high frequency current should not be used on clients who are pregnant, suffer from epilepsy, who have high blood pressure, a pacemaker, metal implants or ?
- A.
Arthiritis
- B.
Asthma
- C.
Albino skin
- D.
Skin cancer
Correct Answer
B. AsthmaExplanation
High frequency current is a type of electrical current that is commonly used in beauty treatments. It is not recommended to use high frequency current on clients who have certain medical conditions, such as asthma. This is because asthma is a respiratory condition that can be triggered or worsened by electrical stimulation. Therefore, using high frequency current on a client with asthma could potentially exacerbate their symptoms and cause discomfort or harm.Rate this question:

Positive pole (anode) includes
- A.
Decreaces blood supply
- B.
Opens pores
- C.
Softens tissues
- D.
Emulsifies grease deposits
Correct Answer
A. Decreaces blood supplyExplanation
The positive pole (anode) is known to decrease blood supply. When the positive pole is applied to the body, it causes vasoconstriction, which is the narrowing of blood vessels. This constriction reduces the flow of blood to the area, resulting in a decrease in blood supply.Rate this question:

Negative pole (cathode) using galvanic current from the posittive toward the negative pole forces ?
- A.
Chemical changes when it passes through the tissues
- B.
Introduces water soluble products into the skin
- C.
Acidic substances into deeper tissues
- D.
Muscle contractions of the face and scalp
Correct Answer
C. Acidic substances into deeper tissuesExplanation
The correct answer is "acidic substances into deeper tissues." When galvanic current is applied from the positive pole (anode) to the negative pole (cathode), it causes chemical changes to occur as it passes through the tissues. These chemical changes result in the introduction of acidic substances into deeper tissues.Rate this question:

Desincrustation is a process used to treat
- A.
Sunburns
- B.
Wrinkling
- C.
Dark spots removed from face
- D.
Acne
Correct Answer
D. AcneExplanation
Desincrustation is a process used to treat acne. It involves the use of a galvanic current to soften and liquefy sebum and other impurities in the pores, making it easier to remove them. This treatment can help to unclog pores, reduce inflammation, and improve the overall appearance of the skin.Rate this question:

What produces moist uniform heat that can be applied to the head or face
- A.
Ultraviolet rays
- B.
Tesla high frequency current
- C.
Steamer or vaporizer
- D.
Cold rags
Correct Answer
C. Steamer or vaporizerExplanation
A steamer or vaporizer produces moist uniform heat that can be applied to the head or face. Ultraviolet rays are not used for producing heat and Tesla high frequency current is not typically used for this purpose either. Cold rags do not produce heat at all. Therefore, the correct answer is steamer or vaporizer.Rate this question:

Correct Answer
B. 60Explanation
Infrared rays make up 60% of natural sunlight. Infrared rays are a type of electromagnetic radiation that has longer wavelengths than visible light. They are not visible to the human eye but can be felt as heat. Sunlight consists of various types of electromagnetic radiation, including infrared rays. The given answer suggests that 60% of the energy in natural sunlight is made up of infrared rays.Rate this question:

- B.
90
- C.
45
- D.
5
Correct Answer
D. 5Explanation
Ultraviolet rays make up a very small percentage of natural sunlight, approximately 5%. This is because sunlight consists of a broad spectrum of electromagnetic radiation, including visible light, infrared rays, and ultraviolet rays. While ultraviolet rays are responsible for causing sunburn and other skin damage, they make up only a small fraction of the overall sunlight.Rate this question:

What are used to make reactions happen more quickly
- A.
A vibrator
- B.
Heat lamps
- C.
Catalysts
- D.
Electromagnetic radiation
Correct Answer
C. CatalystsExplanation
Catalysts are substances that are used to increase the rate of a chemical reaction without being consumed in the process. They work by providing an alternative pathway for the reaction to occur with lower activation energy. This lowers the energy barrier for the reaction, allowing it to happen more quickly. Unlike other options such as a vibrator, heat lamps, or electromagnetic radiation, catalysts specifically facilitate chemical reactions and are not consumed or altered in the process.Rate this question:
