Why is hair attracted to a comb?
Hair is attracted to a comb because of the buildup of static electricity on the comb and on the hair. This buildup occurs when you pass the comb through the hair, and can be reduced or eliminated by adding a little bit of water to the comb or to the hair. Depending on the material of the comb, either the comb will be positively charged and the hair negatively charged, or it could be the other way around. Since opposing charges attract each each, the hair then is attracted to the comb.
Describe a case in which electrical energy is converted into thermal energy?
hair dryer, electrical energy enters the hair dryer and is converted to kinetic energy as a small motor spins a fan blade the electrical energy is converted to thermal by a grind of wires that heat up
What about the comb?
Combs are used to detangle and style hair by running through it. They come in various sizes, shapes, and materials to suit different hair types and styling needs. Proper care of combs, such as cleaning them regularly, can help maintain healthy hair.
What type of joint movement is used to comb hair?
Flexion and extension of the elbow joint are utilized to comb hair, along with supination and pronation of the forearm. This involves a combination of movements that allow for the arm to move in different directions to effectively comb the hair.
Give a practical example of static electricity?
An example is rubbing your head with a balloon. If you rubbed hard enough, your hair should stand up. Also, when you are VERY close to lightning, your hair stands up!!
How is a hair dryer an example of electrical energy?
A hair dryer converts electrical energy from the power outlet into heat energy and kinetic energy to blow hot air. This demonstrates the transformation of electrical energy into different forms of energy for practical use.
Why does the hair crackles when you comb your hair briskly with a plastic comb?
When you comb your hair briskly with a plastic comb, it can create static electricity. Static electricity occurs when objects with opposite charges rub against each other, resulting in a buildup of electrical charges. This buildup causes hair strands to repel each other, leading to a crackling or popping sound.
What form of energy is formed when comb is mb is placed near the dry bits of paper?
When a comb is rubbed against hair or another material, it becomes electrically charged through the process of triboelectric charging. When this charged comb is placed near dry bits of paper, it creates an electrostatic field that can induce polarization in the paper. This results in an attractive force between the comb and the paper, causing the paper bits to be drawn towards the comb. Thus, the energy involved is primarily electrical energy in the form of electrostatic energy.
When you place a comb in bits of paper it does not stick but if you run the comb through your hair it sticks after combing your hair?
The comb attracts the bits of paper when you rub it against your hair because your hair becomes charged with static electricity as the comb runs through it. The charged hair acts as a magnet, allowing the paper bits to stick to the comb. When the comb and paper bits are initially placed together without running through hair, there is no transfer of static charge to attract the paper.
What is the future tense of comb?
The verb forms are comb, combs, combing, combed. Example sentence:Please comb your hair.He combs his hair every five minutes.We're combing the carpet for the diamond from my ring.She combed her hair and washed her face.
What form of energy is formed when the comb is placed near the hair?
Static Electricity
What force do you use if you comb your hair?
when you comb your hair the force you use is a pull force.
What is electrical energy transformed into in a hair dryer?
Electrical energy in a hair dryer is transformed into heat energy, which is used to dry and style hair by evaporation of water. The heating element within the hair dryer converts the electrical energy into thermal energy, which is then transferred to the air blown out of the dryer.
How do you comb hair?
run the comb through the hair
What is an example of energy transformation when used of getting ready for school?
When getting ready for school, electrical energy from a hairdryer is transformed into heat energy to dry your hair.
What form of energy is flat iron?
A flat iron typically uses electrical energy to heat up and style hair. The electrical energy converts into heat energy that is used to straighten or curl hair.
What type of energy do hair straighteners use?
Hair straighteners typically use electrical energy, which is converted into heat energy to style the hair by passing it through heated plates.
