Magnus effect and dynamic lift- The upward force experience by a body when it moves through a fluid is called dynamic lift . Such a lift is felt by airfoil , aircraft win etc. Couse behind it can be explained by Bernoulli’s theorem . It also explain why a spinning ball is deviated from its […]
This assignment contains Important numericals of surface tension which is solved . solution is given just below the questions. 1.The surface tension of the soap solution is 30 x 10-3N/m .How much work is done to increase the radius of the soap bubble from 1.5 cm to 3 cm . Ans- 5.091 x 10-4 j. […]

Surface energy
Before to learn or to know surface energy students must know surface tension. To know about the surface tension click here- Surface energy- It is given as the work done to increase the unit area of a liquid .Or, It is the energy required to remove a molecule completely from a liquid. Or, The molecules at […]

Surface tension
Surface tension– It is the property of a free surface of liquid to get minimum surface area . The property of a liquid at rest by virtue of which its free surface behaves like a stretched elastic membrane and tries to occupy as small an area as possible called surface tension. As we know in […]
