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.

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

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.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
