Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice :
STATEMENT-1 : Pascal's Law is the working principle of a hydraulic lift.
STATEMENT-2 : Pressure is equal to thrust acting per unit area.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 : Two row boats moving parallel to one another are pulled towards one another. STATEMENT-2 : When the boats are close to each other, the velocity of water between them increases and pressure falls according to Bernoull's theorem.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 : The velocity increase, when water flowing in broader pipe enter a narrow pipe. STATEMENT-2 : According to equation of continuity, product of area and velocity is constant.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 : Ratio of normal stress to volumetric strain is bulk modulus of given gas. STATEMENT-2 : Compressibility is the reciprocal of bulk modulus.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 Falling raindrops acquire a terminal velocity. STATEMENT-2 A constant force in the direction of motion and a velocity dependent force opposite to the direction of motion, always result in the acquisition of terminal velocity.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 A rain drop after falling through a certain distance attains a constant velocity. STATEMENT-2 The viscous force for spherical body is proportional to its speed. Hence after falling through a certain distance viscous drag and buoyant forces balance the gravitational force.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 Viscosity of liquid increases rapidly with the rise of temperature. STATEMENT-2 Viscosity of liquid is the property of liquid by virtue of which it opposes the relative motion amongst its different layers.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 Steel is more elastic than rubber. STATEMENT-2 When same deformation is produced in two identical bodies of these material greater restoring force develops in the steel body.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 1kg of cotton fibre will weight less lens in air when made more fluffy. STATEMENT-2 Weight of air in cotton will cancel out with the force of extra buoyancy acting on it.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 If a body is floating in a liquid, the density of liquid is always greater than the density of solid. STATEMENT-2 Surface tension is the property of liquid surface.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 In the steady flow of an ideal fluid, the velocity at any point is same for different fluid particles. STATEMENT-2 Steady fluid flow is the unaccelerated fluid flow.
