Initially, the calibration of the dynamometer was checked, and a reading of 30 N was found when the cube was attached to the dynamometer and suspended in the air. When the cube was immersed in the lake water until half of its volume was submerged, a reading of 24 N was recorded on the dynamometer. Considering that the local acceleration of gravity is 10 m/s², the density of the lake water, in g/cm³, is A) 0.6. B) 1.2. C) 1.5. D) 2.4. E) 4.8. ================== Follow us on social media: 📱 Instagram:   / thalesquirino   📱 Twitter: https://x.com/fisiquei Check out the complete playlist of ENEM 2011 Resolutions: 👉   • ENEM 2011 - Em um experimento realizado pa...   Professor Thales Quirino Medeiros ================== #ENEM #physics #medicine #studies #education
