NEET Physics Power Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Watt | (i) 746 W |
| (b) Horse-power | (ii) 1 J s –1 |
| (c) Kilowatt hour | (iii) 3.6 × 10 6 J |
| (d) Energy usage | (iv) 1000 W × 10 h |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-ii, b-i, c-iii, d-iv
a-i, b-iv, c-ii, d-iii
Correct Answer
Detailed Explanation
Watt is defined as 1 J s –1, while horse-power is equivalent to 746 W. A kilowatt hour represents 1000 W used over one hour, equating to 3.6 × 10 6 J of energy. Thus, the correct matches are a-ii, b-i, c-iii, d-iv.
