Match the following with the correct answer: (1) Work (A) Chemical energy converts into electrical energy (2) Battery (B) Sound energy converts into electrical energy (3) Power (C) Kilowatt-hour (4) Microphone (D) Joule
This question requires matching physics concepts and units with their correct definitions or associations. We need to pair each item from the first list (Work, Battery, Power, Microphone) with the correct item from the second list (Chemical energy converts into electrical energy, Sound energy converts into electrical energy, Kilowatt-hour, Joule).
Let's analyze each item to establish the correct matches:
$J$.$J \cdot s^{-1}$). The option Kilowatt-hour (C) is a unit of energy, not power. A kilowatt-hour ($kWh$) represents the energy consumed or produced by one kilowatt of power in one hour. While technically mismatched as a direct definition or unit of power, in practical contexts, energy consumption (often billed in kWh) is related to the power rating of appliances and their usage duration. Based on the provided options and the common correct answer alignment, this pairing is likely intended.Here's a breakdown of the matches:
| Item | Description |
|---|---|
| (1) Work | (D) Joule |
| (2) Battery | (A) Chemical energy converts into electrical energy |
| (3) Power | (C) Kilowatt-hour |
| (4) Microphone | (B) Sound energy converts into electrical energy |
Based on the detailed analysis and the derived matches (1-D, 2-A, 3-C, 4-B), we look for the option that reflects this specific order.
Option 1 lists the matches as: 1 - D, 2 - A, 3 - C, 4 - B.
This option accurately represents the pairings derived from the question, including the association of Power with Kilowatt-hour.
