What is the relationship between electric field and conductor surface at equilibrium?

• The field is parallel to the surface
• The field is perpendicular to the surface
• The field is diagonal to the surface
• The field has no specific orientation

What happens to charges in a capacitor after the battery is removed?

• They immediately dissipate
• They flow back to the battery
• They remain due to electrostatic attraction
• They change polarity

What type of energy conversion occurs in a battery?

• Mechanical to electrical
• Chemical to electrical
• Thermal to electrical
• Nuclear to electrical

Which properties characterize a metal?

• Poor conductivity and dull appearance
• Lustrous appearance and good conductivity
• Non-conductive and shiny
• Only conducts heat, not electricity

How is acceleration defined?

• The total distance traveled
• The rate of velocity change
• The total speed achieved
• The direction of motion

What are the two components needed to express a quantity?

• Direction and magnitude
• Speed and time
• Numerical value and unit
• Mass and volume

What is the purpose of a coordinate system?

• To measure time only
• To define object position using numerical values
• To calculate speed only
• To measure temperature changes

How does a tensor field differ from vector and scalar fields?

• It only exists in one dimension
• It's a more general form that can represent both
• It only works with temperature
• It only measures force

How does the force on an electron between charged sheets compare to near a single sheet?

• It's half as large
• It's the same
• It's twice as large
• It's four times as large

What type of acceleration does a charged particle experience between parallel charged sheets?

• Variable acceleration
• Zero acceleration
• Exponentially increasing acceleration
• Constant acceleration
