Two soap bubbles of radii 3cm and 4cm
WebCorrect Option (c) Air flows from the smaller bubble to the bigger. Explanation: The excess pressure inside the soap bubble is inversely proportional to radius of soap bubble l.e. , p ∝ 1/r,r being the radius of bubble, It follows that pressure inside a smaller bubble is greater than that inside a ** bubble.. Thus, if these two bubbles are connected by a tube, air will … WebAug 27, 2024 · Answer: Option (1) 5 cm. Explanation: if the radius of the soap bubble is r, T is surface tension then. Pressure inside the soap bubble = 4T/r Let the combined radius of …

WebAnswer (1 of 4): Let bubble a have 4r radius while bubble b have 3r. Also let's bubble a have W_a work done on itself to move a distance ds and bubble b have W_b work done on itself to move a distance ds. We shall for this consider the velocity of motion of both the bubbles to be same, i.e., both... WebApr 29, 2024 · Two spherical bubbles of radii R 1 and R 2 , which contain air, coalesce into a single bubble of radius R 3 . If the ambient air pressure is p0 and the merging process is isothermal, derive a formula that relates R 3 to ( p 0 , R 1 , R 2 , ℑ ).
WebThe excess pressure inside the soap bubble is inversely proportional to the radius of soap bubble i.e. P ∝1/r, r being the radius of the bubble. It follows that pressure inside a smaller bubble is greater than that inside a bigger bubble. Thus, if these two bubbles are connected by a tube, air will flow from smaller bubble to bigger bubble and the bigger bubble grows … WebApr 27, 2024 · Under isothermal condition two soap bubbles of radii `r_(1)` and `r_(2)` coalesce to form a single bubble of radius r. The external pressure is `p_(0) asked May 18, …
WebIn the above case, the radius of curvature for the smaller and larger bubbles are 3 cm and 9 cm respectively. Hence the pressure in the smaller bubble would be higher in comparison to the pressure inside the larger bubble. The excess pressure in the larger bubble would be ~1 N/m 2 and in the smaller bubble would be ~3 N/m 2. WebLet r 1 and r 2 be the radii of two given soap bubbles and r be that of the coalesced bubble. Here, r 1 = 30 cm and r 2 = 4 cm. Since a soap bubble has two free surfaces, total surface area of the coalesced bubble = 2 × 4 πr 2 = 8 πr 2. Potential energy of the coalesced bubble, i.e., W = 8 πr 2 T …(i)
WebDec 23, 2024 · Sol: Initial radius of soap bubble R 1 = 3cm = 3 × 10-2 m. Final radius of soap bubble R 2 = 4cm = 4× 10-2 m. Work done in blowing soap bubble from radius R 1 to R 2 is.
