Question

Q 77. What is the specific gravity of
the metal, if the weighs 6.5 kgf in air
and 3.5 kgf in water ? एका धातूचे हवेतील
वजन ६.५ किलो ग्रॅम फोर्स आणि पाण्यातील
वजन ३.५ किलो ग्रॅम फोर्स असेल तर धातूचे
विशिष्ट गुरुत्व काय आहे ?​

Answer 1

Answer:

Obviously the body replaces a volume of water or air that has a weight difference of 3 units as Water gas a density of roughly 1000 kg/m^3. The volume is about 3 l. Therefore the density is 6,5 kg/3 l= 2,17 kg/l = 2167 kg/m^3.
