Question

Regan has an empty glass cup. It has a mass of 0.3 kg. She drops the cup on the ground and it shatters into several pieces. If she collected all of the pieces of the cup, how much mass would all of the pieces have combined?
A: Less than 0.3 kg
B: More than o.3 kg
C: There is n way to determine the mass of the shattered glass
D: exactly 0.3 kg

Answer 1

hint: mass is conserved, so if she picks up ~all~ of the pieces like the original problem implies, the mass should be equal to the original mass. However, in all likelihood, there will be some fragments she misses and the total mass will be lower
