conduction
convection
friction
induction
The image shows charging by...

During a storm the base of a cloud becomes negatively charged. Lighting occurs soon after because:
The positively charged particles in the cloud attract to the positive charge of the ground.
The negatively charged particles in the cloud attract to the positive charge of the ground.
The negatively charged particles in the cloud attract to the negative charge of the ground.
When a piece of metal becomes negatively charged it has:
Gained electrons
Gained protons
Lost protons
When you walk across a nylon carpet, you become negatively charged. When you then touch a metal handle you receive a shock because:
Electrons jump from you to the handle
Protons jump from you to the handle
Electrons jump from the handle to you

the balloon will spin in circles
the balloon will be repelled by the rod
the balloon will be attracted to the rod
What is the name of this device that is used to detect charges?
flask

the distance of charged objects.
the force of charged objects.
the charge of charged objects.
Which part of Coulomb's Law is always squared?
distance

Coulomb's constant
force
Coulomb's law says that the force between any two charges depends
directly on the size of the charges
inversely on the square of the distance between the charges
both are correct
neither are correct
When distance increases, electrostatic force ____________; we call this relationship ____________ proportional
decreases;directly
decreases;inversely
increases;inversely
increases;directly

What is thunder?
sound created from clouds crashing into each other
sound created of superheated air expanding from lightning and air molecules crashing into each other creating a shock wave.
electric impulses produced in clouds
sound created from high speed winds
How Does Lightning Occur?
When the positive and negative and negative charges are weak enough to create a spark
When the positive and negative charges are strong enough to create a spark
When the positive and positive charges are strong enough to create a spark
When the negative and negative charges strong enough to create a spark
Lightning can occur from cloud to ground, cloud to cloud, even cloud to air. But how does the ground become charged?
Induction
Conduction
Convection
Friction
Which statement best describes the electric fields in the image?
The charges are neutral.
Both charges are negative, so the field lines are alike.
The field lines move toward a positive charge and away from a negative charge.
The field lines move away from a positive charge and toward a negative charge.
Based on the arrangement of the electric field lines in the diagram, what are the charges?
both charges are the same
the charges are opposite
they are neutral; no charge
