Water and Kerosine are drawn respectively into the two limbs of a Hare’s apparatus. The destiny of water is 1.0gcm\(^{-3}\) and the density of kerosine is 0.80gcm\(^{-3}\). If the height of the water column is 20.0cm, calculate the height of the kerosine column.
- 1.6cm
- 16.0cm
- 20.0cm
-
25.0cm
The correct answer is: D
Explanation
Devices with different liquids
d\(_1\)h\(_1\) = d\(_2\)h\(_2\)
1 × 20 = 0.8 × h
| h | = | 20
0.8 |
= | 25cm |
