NEET Physics Power Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) 1 watt | (i) 746 W |
| (b) 1 hp | (ii) 1 J s⁻¹ |
| (c) 1 kWh | (iii) 3.6 × 10⁶ J |
| (d) 100 W bulb | (iv) 10 hours |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iii, c-i, d-iv
a-i, b-iv, c-ii, d-iii
Correct Answer
Detailed Explanation
1 watt is defined as 1 J s⁻¹, while 1 horsepower (hp) is equivalent to 746 W. Additionally, 1 kWh corresponds to 3.6 × 10⁶ J, and a 100 W bulb consumes energy over a specified duration. This matches the power definitions and conversions provided in the NCERT context.
