An air bubble of radius

2.0 \mathrm{~mm}

is formed at the bottom of a

3.3 \mathrm{~m}

deep river. Calculate the radius of the bubble as it comes to the surface. Atmospheric pressure

=1.0 \times 10^5 \mathrm{~Pa}

and density of water

=1000 \mathrm{~kg} \mathrm{~m}^{-3}

.

View answer and explanation

Correct option: D

2.2 mm

Option D (2.2 mm) is correct because it is the radius calculated using Boyle's law, considering the pressure change as the bubble rises.

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}

near the surface. If the river is

5 \mathrm{~m}

deep, find the shearing stress between the horizontal layers of water. The coefficient of viscosity of water

=10^{-2}

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
