What part of a circuit is designed to turn electricity into another form of energy? Is it the Switch, Resistor, Voltage or Wires?
Resistor
Is sound a longitudinal or transverse wave?
Longitudinal.
We hear sound as having different pitch and volume. What wave characteristic is responsible for the volume of the sound and which wave characteristic is responsible for the pitch?
(possible answers: wavelength, frequency, crest, trough, amplitude)
volume - Amplitude
pitch - frequency/wavelength
When light passes from glass to a second medium, it bends toward the normal. You can conclude that the second medium is (more/less) dense than glass?
more dense

True or False: A circuit with a current of 1A and a resistance of 6 ohms has a potential difference of 1/6 volts.
False. V=IR, so the voltage would be 6 Volts

the most dense - Iron
What is refraction and does it occur in daily life?
Refraction is the bending of light and is most well known for producing rainbows.
