Question

the piece of wood of 28 cm cube volume and the piece of glass of 1 cm cube volume are tied with each other. the density of wood is 0.6 gram per centimetre cube and the density of Glass is 11.3 gram per centimetre cube according to the calculation both piece will A.swim in water B. sink in water C. sink in the middle D. none of these​

Answer 1

28×0.6= <1 flot

1×11.3 =>1 shrink

Answer 2

Answer:

it will. A. swim in water

Explanation:

Mass of piece of wood = 0.6 * 28 = 16.8 g

Mass of piece of glass = 11.3 * 1 = 11.3 g

total mass = 16.8+11.3 = 28.1 g

total volume = 28+1 = 29 cm cube

so density = 28.1 /29 = 0.97g/cm cube

since the density of two pieces on tying is less than the density of water so the pieces will float on water .
