Plz help me it’s a true or false question A shorter wire will allow electricity to
move through at a higher rate than a
longer wire.
A short, thick, cold wire is the best
conductor
How well a material conducts current is
an internal factor affecting resistance.
If you double the length of a wire, you cut
the resistance in half.
If you double the thickness of a wire, you
cut the resistance in half.
Superconductors have no measurable
resistance
The higher the temperature of the
conductor, the lower the resistance.
The resistance in a wire with less
thickness is less.
Thickness, length, and temperature are
internal factors that affect resistance.
When a light is first switched on the light
bulb's filament has a lower resistance
than after it gives off light for awhile.

-- A shorter wire will allow electricity to  move through at a higher rate than a  longer wire . . . True, but "rate" is a poor way to say it. It should say "a higher current".  

-- A short, thick, cold wire is the best  conductor . . .  True

-- How well a material conducts current is an internal factor affecting resistance . . . True

-- If you double the length of a wire, you cut  the resistance in half . . . False. Double the length also means double the resistance.

-- If you double the thickness of a wire, you  cut the resistance in half . . . True

-- Superconductors have no measurable  resistance . . . True. They literally have NO resistance.

-- The higher the temperature of the  conductor, the lower the resistance . . . False. Higher temperature means higher resistance, for almost all conductors.

-- The resistance in a wire with less  thickness is less . . . False. We just said, up above  in Question-#5, "If you double the thickness of a wire, you  cut the resistance in half". Less thickness means more resistance. Just like a highway with fewer lanes.

-- Thickness, length, and temperature are  internal factors that affect resistance . . . False. They affect resistance, but they're external factors.

-- When a light is first switched on the light  bulb's filament has a lower resistance  than after it gives off light for awhile . . . True. Look back 3 questions from here, where it says "Higher temperature means higher resistance".
