When a liquid rises inside a capillary tube, the weight of liquid column inside the capillary tube is supported
1 entirely by the force due to surface tension
2 partly by atmospheric pressure and partly by force due to surface tension
3 by atmospheric pressure
4 partly by the force due to surface tension
Explanation:
A When a liquid rises inside a capillary tube, the weight of liquid column inside the capillary tube is supported entirely by the force due to surface tension.

The function of hydraulic mechanism in a wheel chair is based on
1 Pascal's principle
2 Archimedes' principle
3 Bernoulli's principle
4 Stefan-Boltzmann law
Explanation:
A The function of hydraulic mechanism in a wheel chair is based on Pascal's principle. Pascal's principle:- An external pressure applied to an enclosed fluid is transmitted uniformly through out the volume of the liquid.

A boat carrying a number of large stones is floating in a water tank. What would happen to the water level if a few stones are unloaded into water?
1 Rises
2 Falls
3 Remains unchanged
4 Rises till half the number of stones are unloaded and then begins to fall.
Explanation:
B When a few stones are unloaded into water then water level will falls because when stone was in the boat and floating, volume of water displaced has a mass equal to the stone. But when stone has drooped it displace equal to its volume.

The meniscus of a liquid contained in one of the limbs of a narrow U-tube is placed between the poles of an electromagnet with the meniscus in a line with the field. The liquid is seen to rise to the line. This indicate that the liquid is
1 Ferromagnetic
2 Paramagnetic
3 Diamagnetic
4 Non magnetic
Explanation:
B Paramagnetic materials are materials that tend to get weakly magnetized in the direction of the magnetizing field when placed in a magnetic field. As given in the question the meniscus of a liquid contained in one of the limbs of a narrow U-tube is placed between the poles of an electromagnetic with the meniscus in a line with the field. The liquid get magnetized as it seen to rise to the line, so the liquid behaves as paramagnetic materials.
