What type of lens is a tumbler filled with water ?
Assertion : A star will appear to twink le if seen from free space (say moon) Reason : An air bubbles inside water behave like a convergent lens .
Statement-1 : If there is a water bubble in air then excess pressure inside it is (4T)/(R) , where T is surface tension of water and R is the radius of the bubble. Statement-2 : If there is a water drop in air then excess pressure inside it is (2T)/(R) 1 Statement-3 : If there is an air bubble in water then excess pressure inside it is (4T)/(R)
What will happen to the potential energy of an air bubble in water when it rises in water ?
Suppose there is an air bubble of radius inside the air cavity of radius R inside a water drop of radius 3R as shown in figure. The ratio of gauge pressure at point C to gauge pressure at point B is: -B
