Answer:

B. Edison thought that the secret to a better bulb could be found

Explanation:

The first electric bulb was made by Humphrey Davy in 1800. He did experiments with electricity and invented electric battery. He connected a piece of carbon with his battery with wires and saw that the carbon began glowing and produced light. He called it electric arc.

Later English physicist Joseph Swan also invented bulbs but his bulbs were not fit for day to day use because he used carbon filaments in his bulbs that burned quickly.

The bulb invented by Thomas Alva Edison was successful everyday use. He experimented with thousands of different filaments and found that carbon filaments didn't burn and glowed longer if placed in oxygen free bulb. He eventually managed to produce a bulb that glow for more than 1500 hours.

Swan's lightbulb didn't last as long as Edison's and required more current to operate at the same power level as Edison's. Higher current meant you need thicker wire to power it.

san4es73 [151]

Answer:

The statement that makes the most accurate claim about swift and Montagu's attitudes on gender D. Both depict negative gender relations because Swift is repulsed by the female body and Montagu is annoyed by male self-importance.

Explanation:

Swift's poem shows a very negative attitude toward women because it shows a big aversion to their body, making statements as something that deserves to be depicted. On the other hand, Montagu's poem makes fun of men, but not about physical terms but about personality issues, for being pompous and foolish.
