Question

Ling built a circuit with three light bulbs. She observed that all three light bulbs glowed.

Then she removed one light bulb, and the others stopped glowing. She explained that the

other light bulbs had burned out. How could Ling test her explanation? *

(1 Point)

Replace the battery and observe whether the two lights come back on.

Take another light bulb out of the circuit and observe whether the last one comes on.

Wait another 10 min to see whether the light bulbs suddenly start glowing again.

Put the light bulb that was removed back into the circuit and observe whether the other lights come on.

Answer 1

Put the light bulb that was removed back into the circuit and observe whether the other lights come on.

Step-by-step explanation:

If all three bulbs initially glowed and she supposes that after removing the first bulb, the others stopped glowing because they burned out, then she must replace the original bulb and see if the other two bulbs will glow.

If all three bulbs don't glow after replacing the first one, then all the bulbs may have probably burned out.
