what are the applications of archimedes principle???
a body weighs 25 kg on the surface of the earth. if mass od the earth is 6.0*1024 kg, the radius of the earth is 6.4*106 m and the universal gravitational constant is 6.7*10-11Nm2/kg2, calculate

RELATIONSHIP BETWEEN SMALL g AND CAPITAL G
A test tube is loaded with lead shots so that it floats in a liquid immersed to a mark on the tube. The total weigh of tube and lead shots is 30 gf. the tube is then placed in water and lead shots are added to sink the tube to the same mark. Now, the tube and lead shots weigh 35 gf. Calculate the relative density of liquid.
