A cubical block of iceberg of density `rho` is floating on the surface of water. Out of its height L, fraction x is submerged in water. The vesel is in an elevator accelerating upward with acceleration a . What is the fraction immersed?

Iceberg floats in water with part of it submerged. What is the fraction of the volume of iceberg submerged if the density of ice is rho_1 = 0.971 g cm^-3 ?

Sea water at frequency v=4xx10^8Hz has permitivity epsilon~~80epsilon_0 , pemeability mu=mu_0 and resistivity rho=0.25Omega-m . Imagine a parallel plate capacitor immersed in sea water and driven by an alternating voltage source V(t)=V_0sin(2pivt) . What fraction of the conduction density is the dispalcement current density?
