Answer 1

Answer:

(b) fall at the rate of 1 cm/h will be the answer.

Explanation:

since half of the candle floats up when in initial equilibrium density of the candle is half of the density of water. Thus it always remains half inside water and half outside. Thus after an hour the length of candle would decrease by 2 cm and half of it. would remain water and half outside thus the fall in the top of the candle would be 1cm

thus rate of flow of top of the candle 1cm/h
