Answer:
No, the piece of Wood will not follow.
a) Volume = 0.00105 m³
b) Density of Wood = 1200 kg/m³
Step-by-step explanation:
For the piece of wood to float on salt water, the density of the wood should be less than 1030kg/m³
First we'll calculate the volume of the piece of wood, which later we'll use to find the density.
a) Volume of Wood
Volume is given by 7 cm × 10 cm × 15 cm
Convert all the values into meters.
7 cm = 7/100 = 0.07 m
10 cm = 10/100 = 0.10 m
15 cm = 15/100 = 0.15 m
Calculate Volume:
Volume = 0.07 m × 0.1 m × 0.15 m
Volume = 0.00105 m³
b) Density of Wood
Formula for density is given by
Density = Mass / Volume
Where
Volume = 0.00105 m³
Mass = 1260 g = 1260/100 = 1.260 kg
Density = 1.260 kg/0.00105 m³
Density of Wood = 1200 kg/m³
As Density of Wood ≥ Density of Salt water , the piece of Wood will not float.
