An iron anchor has a density of 480kg/m³ and weighs 250kg in air. If it is immersed in a sea water that has a density of 64kg/m³,how much force would be required to lift it while it is immersed? |

Answer» Answer: If you WANTED to immerse the anchor, you WOULD have to apply a downward force of 817.5 N to fully immerse this “anchor” completely under the water. This anchor has a mass of 250 kg. Therefore, it's WEIGHT is: W=mg=(250KG)(9.81ms2)=2452.5N downward. |
