Characteristics of Electricity

Why are there so few electric-only vehicles in use?
1. Many heavy batteries are needed, and they need to be recharged frequently
2. Electric vehicles are too powerful and difficult to control
3. Brake technology must still be perfected for electric vehicles
4. Electric vehicles increase air pollution
How do hybrid vehicles differ from traditional gasoline engine vehicles?
1. Hybrid vehicles have both a gasoline and electric motor
2. Hybrid vehicles have only an electric motor
3. The gasoline engines in hybrid vehicles are generally larger
4. Hybrid vehicles do not have a fuel tank
Which of the following best describes static charge?
1. Electric charges that can be collected and held in one place
2. Electric charges that cannot move
3. Electric charges that are neutral
4. Electric charges that are only found on the inside of objects
Which of the following best describes the charges in an atom?
1. Electrons are the lightest, negatively charged atomic particles
2. Electrons are the lightest, positively charged atomic particles
3. Protons are the heaviest, negatively charged atomic particles
4. Electrons are located in the nucleus
Due to an interaction with another atom, a neutral atom of sodium loses an electron. How is the charge of the sodium atom affected?
1. The sodium atom now has a positive charge
2. The sodium atom now has a negative charge
3. The charge of the sodium atom is unaffected
4. The neutral charge of the sodium atom is increased
Use the following information and image to answer the next 2 questions.

Photo A shows a cat being rubbed by a balloon. After the cat is rubbed, the balloon is slowly lifted, and the cat's fur stands on end (photo B).

What occurs as a result of the rubbing?
1. Electrons are transferred from the cat fur to the balloon
2. Protons are transferred from the cat fur to the balloon
3. Heat from friction transforms into excess electrons
4. The static electric charge of the balloon is discharged
Why does the cat fur stand on end?
1. The cat's fur has become statically charged
2. The balloon is exerting a magnetic pull on the fur
3. The cat's fur has increased in neutrality
4. The cat's fur is rapidly losing protons
The unit of electric charge is the
1. coloumb.
2. electron.
3. volt.
4. newton.
Which of the following best describes a conductor?
1. A material that allows electrons to travel freely
2. A material that prevents electron flow
3. A material that can retain a static charge
4. A material that holds protons on its surface
In an experiment a wool sock is rubbed vigorously on a piece of plastic. This results in the plastic acquiring a static charge. When measured 10 minutes later, it is found that the plastic is still holding much of the original charge. The result of this experiment indicates that
1. the plastic is an insulator.
2. the plastic is a conductor.
3. the plastic is a proton absorber.
4. the plastic allows for the free movement of electrons.
