Which of the following is the smallest component of an element that still retains the properties of the element?
atom
An atom is the smallest component of an element that still retains the properties of the element.
Spark plugs receive current from the:
distributor
Spark plugs receive current from the distributor and use it to spark combustion in the combustion chamber of a cylinder.
The standard unit of energy is the:
Joule
The Joule (J) is the standard unit of energy and has the unit \({kg \times m^2} \over s^2\).
What is 7a3 + 7a3?
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
7a3 + 7a3 = 14a3
A vehicle's lighting system is protected from current spikes by:
fuses and circuit breakers
The lighting system consists of interior lights, instrument panel lighting, headlights, and taillights. Like household electrical circuits, the vehicle's lighting system is protected from current spikes by fuses and circuit breakers.
The valence shell of n insulator is how full of electrons?
more than half full
Insulators have valence shells that are more than half full of electrons and, as such, are tightly bound to the nucleus and difficult to move from one atom to another.
In the classification of life, which of the following is not a kingdom?
bacteria
Below domain, life is classified into six kingdoms: plants, animals, archaebacteria, eubacteria, and fungi. The last kingdom, protists, include all microscopic organisms that are not bacteria, animals, plants or fungi. (Archaebacteria and eubacteria are sometimes combined into a single kingdom, monera.)
A compound is a substance containing two or more different chemical elements bound together by what kind of bond?
chemical
A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
What is the voltage of most household electrical systems in the United States?
110V
Most households use electricity with a voltage of 110V.
