# Water and Kerosine are drawn respectively into the two limbs of a Hare's apparatu...

### 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

### Explanation:

Devices with different liquids
d$$_1$$h$$_1$$ = d$$_2$$h$$_2$$
1 × 20 = 0.8 × h

 h = 20 0.8 = 25cm

## Dicussion (1)

• Devices with different liquids
d$$_1$$h$$_1$$ = d$$_2$$h$$_2$$
1 × 20 = 0.8 × h

 h = 20 0.8 = 25cm
