Water and Kerosine are drawn respectively into ... - JAMB Physics 2019 Question
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.
A
1.6cm
B
16.0cm
C
20.0cm
D
25.0cm
correct option: d
for the different liquids,
d\(_1\)h\(_1\) = d\(_2\)h\(_2\)
1 × 20 = 0.8 × h
| h | = | 20
0.8 |
= | 25cm |
h = 25cm
