To determine which object would sink in honey with a density of 1.4 g/cm³, we need to compare the density of each object with the density of honey.
- Object 1: 0.9 g/cm³ (sinks in water but floats in honey)
- Object 2: 1.2 g/cm³ (floats in water but still floats in honey)
- Object 3: 0.2 g/cm³ (sinks in water but floats in honey)
- Object 4: 2.3 g/cm³ (denser than honey, will sink)
Objects that have a density greater than 1.4 g/cm³ will sink in honey. Thus, Object 4 with a density of 2.3 g/cm³ would sink in honey.
