What would happen if the switch was taken out of the circuit shown and the wires attached to the switch were connected?
Wires would disappear
Light bulb would stay on
Light bulb would go off
Battery would produce more electricity
Graphite is a good conductor of heat and electricity. What will most likely happen if the graphite part of a pencil is placed in the circuit, closing the circuit?
The light bulb will turn on because graphite insulates electricity when combined with copper wire.
The light bulb will not turn on because the wood in the pencil will cancel out the conductivity of the graphite.
The light bulb will not turn on because the graphite part of the pencil is too narrow to allow electricity to flow through it.
The light bulb will turn on because the graphite will allow electricity to flow through it.
Your Mom was cooking dinner. In order to not get burned, she chose a pot with a handle made of..
metal because it does not catch on fire as quickly as wood
plastic because it is a good conductor of heat.
metal, because it is a good conductor of heat
plastic, because it is not a good conductor if heat
What would happen if part A was removed?
Only the modem would be affected
There would be no energy for the system to function.
Only part D would be affected.
The volume of the phone would be louder.
Which of the following is the role of the wire in the circuit?
changing the electrical energy into light energy
carrying electrical energy to the light bulb
producing energy for the light bulb
turning the light bulb on and off
A class poured 90 degree water in three different cups and let them sit for 30 minutes. The students recorded the beginning and ending temperatures in the chart above.
Based on the information, which item is the BEST insulator of thermal energy?
they all insulate the same
the cup made of glass
the cup made of styrofoam
the cup made of plastic
Which is TRUE about an insulator?
It can be a good conductor.
It allows heat to pass through easily.
It slows energy transfer.
It provides heat to keep materials warm.
Sam and Kim placed boards on the curb to race their identical remote control cars on. Sam's board had a rough surface. Kim's board was smooth. Kim's car won all of the races. Kim's car was faster than Sam's because of
friction
pressure
tension
gravity
