What are the volume and the density of the material

Reference no: EM13553777

A sample of an unknown material appears to weight 300N in air and200N when immersed in alcohol of specific gravity 0.700. What are(a) the volume and (b) the density of the material?

*Please explain the Archimedes' principle of apparentweight and why in the solution you have to subtract 200N from300N*
