NEET Physics Power Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Watt (i) 1 kWh = 3.6 × 10^6 J (b) Horse-power (ii) 746 W (c) Energy used by a 100 W bulb for 10 hours (iii) Unit of power (d) James Watt (iv) Innovator of steam engine
Choose the correct matching:
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-ii, d-i
D
a-iii, b-i, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
The watt is defined as a unit of power (1 J/s) and is correctly matched with its definition. Horse-power is indeed 746 W, and the energy consumed by a 100 W bulb for 10 hours is 1 kWh, which equals 3.6 × 10^6 J. James Watt is known for his contributions to the steam engine, making the pairings correct.
