Two particles with the same charge will __________ or drive away from each other.
repel
Two particles with opposite charges will be ____________ to each other.
attracted
Material with free charged particles that easily flow through it when an electric force acts on it. They allow electricity to flow through them easily
conductors
Materials without free charged particles that do not easily allow electricity to flow through them
inductors
Material that can be made to behave as either a conductor or an insulator of electricity.
semiconductors
When one has connected a conductor, a source of electricity such as a battery and an appliance such as a bulb, one has created an electric ___________
circuit
SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 X 10^18 electrons.
coulomb
The relationship among electrical force, charges, and distance. The electrical force between two charges varies directly as the product of the charges and inversely as the square of the distance between them.
Coulomb Law
The region where electric force may be felt surrounding a charged object. Represented by lines that start on a + charge and end on a - charge.
electric field
to limit the possible values to a discrete multiple of a minimum value
quantized
When an atom has a slight excess of positive charges on one side and a slight excess of negative charges on the other side.
electrically polarized
The energy a charged object possesses by virtue of its location in an electric field
Electric Potential Energy
A field of force surrounding a charged particle; electric field= F/q
Electric Field
measured in volts; called voltage
voltage= electric potential energy/charge
Electric Potential
The charging of an object without direct contact.
induction
The principle that net electric charge is neither created nor destroyed but is transferable from one material to another.
conservation of charge
the study of electric charges at rest
electrostatics
Allowing charges to move freely along a connection between a conductor and the ground.
grounding
A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract.
electrical force
Common laboratory device that can develop high voltages
Van de Graaff Generator
Charged object can have ___________ by virtue of its
location in an electric field.
potential energy
____________ is done when a force moves something
against a the force.

(a) What is the resistance of a Nichrome wire at $0.0^{\circ} \mathrm{C}$ if its resistance is $100.00 \Omega$ at $11.5^{\circ} \mathrm{C}$ ? (b) What is the resistance of a carbon rod at $25.8^{\circ} \mathrm{C}$ if its resistance is $0.0160 \Omega$ at $0.0^{\circ} \mathrm{C}$ ?
physics
What is the relationship between the speed of light and the index of refraction of a transparent substance?
chemistry
Define activation energy. What role does activation energy play in chemical kinetics?
engineering
The speed of the brake drum shown is controlled by a belt attached to the control bar $A D$. Knowing that the coefficient of static friction is $0.30$ and that the brake drum is rotating counterclockwise, determine the minimum value of $a$ for which the brake is not self-locking.
