Two spherical soap bubbles of radii

a

and

b

in vacuum coalesce under isothermal conditions. The resulting bubble has a radius given by

View answer and explanation

Correct option: C

\sqrt {{a^2} + {b^2}}

Option C (

\sqrt{a^2 + b^2}

) is correct because the total surface area of the bubbles remains constant during isothermal coalescence in a vacuum.

The average mass that must be lifted by a hydraulic press is

80 \mathrm{~kg}

. If the radius of the larger piston is five times that of the smaller piston, what is the minimum force that must be applied? A small drop of oil spreads over water because A film of water is formed between two straight parallel wires of length

20 \mathrm{~cm}

with separation of

0.5 \mathrm{~cm}

. The work done to increase the separation by

0.1 \mathrm{~cm}

is: The velocity of water in a river is

15 \mathrm{~m} / \mathrm{s}

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
