3 Layer Liquid Density Experiment - Denser Than You Think! #Shorts #Magnetbrains #Scienceexperiment

Give reason for Liquid have lesser density than solids.

State two experiences that made you think that air exerts pressure (other than those given in the text).

A cylinder of length L floats with its entire length immersed in two liquids as shown in the fig. The upper liquid is water and the lower liquid has density twice that of water. The two liquid are immiscible. The cylinder is in equilibrium with its (3)/(4) lenght in the denser liquid and (1)/(4) of its length in water. The thickness of water layer is (L)/(4) only. Find. (a) the specific gravity of the material of the cylinder. (b) the time period of oscillations if the cylinder is depressed by some small distance (lt(L)/(4)) and released. Neglect viscosity and change in level of liquids when the cylinder moves.

Lead has greater density than iron and both are denser than water. Is the buoyant force on a lead object greater than, less than or equal to the buoyant force on an iron object of the same volume?

Do you think that interference pattern in Young's double slit experiment is the consequence of the superposition of the diffracted waves from the two slits?
