Question

A Eureka can of mass 100g and cross-sectional area 100cm² is filled with water of density 1g/cm³. A piece of metal of mass 20g and density 8g/cm³ is lowered carefully into the can as shown. Calculate:

The total mass of water and Eureka can before the metal was lowered.
(A) 120g
(B) 100g
(C) 1000g
(D) 200g

Answer 1

The total mass of water and the Eureka can before the metal was lowered is 200g.

Step-by-step explanation:

To calculate the total mass of water and the Eureka can before the metal was lowered, we need to add the mass of the can and the mass of the water. The mass of the can is given as 100g. The mass of the water can be calculated using the density formula, density = mass/volume. Since the density of water is 1g/cm³ and the volume of the can is 100cm², the mass of the water is 100g. Adding the mass of the can and the mass of the water, we get a total mass of 200g.
