Question

The mass of an empty bucket of capacity 20 liters is 1.5 kg. Find the mass of the bucket when completely filled with a liquid of relative density of 0.9

Answer 1

Answer:

Explanation:

density of liquid = 0.9×1000kg/m

Volume of bucket = 20 litre

                              = 20×10

=18kg

mass of bucket = 20kg

mass = 38kg

Volume = 2×10
