Explanation:
What is the density of the coin?
Formular for density = Mass / Volume
Mass of coin = 18.82g
Volume occupied = 7.3ml - 5.2ml = 2.1ml
Density = 18.82 / 2.1 = 8.9619g/ml
what is the mass of the iceberg in metric tons (1 metric ton = 1000 kg)?
Density = 0.9I68g/cm^3
Volume = 35,000 m^3 = 3.5e+10cm^3 (Conversion to cm^3)
Mass = Volume * Density = 3.5 * 10^10 * 0.9I68 = 3.2088 * 10^10g
Upon conversion to kg by dividing by 1000
Mass = 3.2088 * 10^7kg
(1 metric ton = 1000 kg)
Mass = 3.2088 * 10^3 metric tonnes
In your own words explain how Archimedes' principle can be used to measure the volume of an irregularly shaped solid.
By definition, all matter has mass and occupy space. Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. And the weight of fluid displaced is the volume of fluid.
So the volume is obtaiined by placing the irregularly shaoed solid and noting the volume of fluif displaced.
what volume of water (d = 1.000g/mL) is about to impact Melinda's head?
Volume of sphere = V = (1 / 6) πd³
Inserting the value of V = 10.7 cm
Volume = 641.43cm³
