what does the top of the TRIBOELECTRIC SERIES mean correct answers they can give up
electrons easily
what does the bottom of the TRIBOELECTRIC SERIES mean correct answers they will most
likely take on electrons
one Coulomb: correct answers 6.3 x 10^18 electrons
A positive charge of one Coulomb means that an object is ____ 6.3 X 10^18 electrons. correct
answers deficient
If a positive charge of one coulomb means This will still result in a spark, but electron flow will
be from the what correct answers the other object to the positively-charged object.
In ___, both negative and positive charges will drift toward the opposite charge. correct answers
fluids
, in __ where the atoms are locked in place, only electrons loosely bound in outer shells will
move. correct answers solids
The Five Laws of Electrostatics: correct answers 1. Like charges repel each other, opposite
charges attract
2. In solid objects, only negative charges (electrons) can move
3. In solid objects, electrical charges exist only on the surface of the object.
4. In solid objects, charge will concentrate at the greatest curvature of the surface
5. The force of electric charge follows Coulomb's Law
1. Like charges ___ each other, opposite charges ____ correct answers repel ; attract
In solid objects, only ___charges can move correct answers negative (ELECTRONS)
in solid objects, __ __exist only on the surface of the object. correct answers electrical charges
In solid objects, charge will concentrate at the what correct answers greatest curvature of the
surface
The force of electric charge follows WHAT LAW correct answers Coulomb's Law
coulombs law formula correct answers F = oldQ/newQ = newD2/oldD2
Q = amount of hcarge
Coulombs Law states that the force of repulsion or attraction between two charges is: correct
answers A. Proportional to the product of the two charges
B. Inversely proportional to the square of the distance between the two charges
Three Methods of Electrification: correct answers Friction
Conduction
Induction
Electrons can be rubbed off of some materials with very loosely-bound electrons onto certain
other materials, even though neither material is charged to begin with correct answers friction
what can cause sudden
discharges of electricity
(sparks), and was a constant
problem with old x-ray
film - Sliding it across
counter tops, out of
cassettes or out of film
