Q. Which of the following factors does NOT affect the buoyant force on an object submerged in a fluid?
A.
Density of the fluid
B.
Volume of the object
C.
Depth of the object
D.
Acceleration due to gravity
Solution
The buoyant force depends on the density of the fluid, the volume of the object submerged, and the acceleration due to gravity, but not on the depth of the object.
Q. Which of the following factors does NOT affect the buoyant force on an object?
A.
Volume of fluid displaced
B.
Density of the fluid
C.
Shape of the object
D.
Acceleration due to gravity
Solution
The buoyant force depends on the volume of fluid displaced, the density of the fluid, and the acceleration due to gravity, but not on the shape of the object.
Q. Which of the following factors does NOT affect the coefficient of kinetic friction?
A.
Surface roughness
B.
Normal force
C.
Material of surfaces
D.
Speed of sliding
Solution
The coefficient of kinetic friction is generally independent of the speed of sliding, while it depends on surface roughness, normal force, and material.
Q. Which of the following factors does NOT affect the entropy of a system?
A.
Temperature
B.
Volume
C.
Pressure
D.
Nature of the substance
Solution
While temperature, volume, and the nature of the substance affect entropy, pressure does not directly affect the entropy of a system in a significant way.
Q. Which of the following factors does NOT affect the equilibrium constant (K) of a reaction?
A.
Temperature
B.
Concentration of reactants
C.
Pressure
D.
Nature of reactants and products
Solution
The equilibrium constant K is only affected by temperature. Changes in concentration or pressure will shift the position of equilibrium but not change the value of K.

Q. Which of the following factors does NOT affect the gravitational force on a satellite?
A.
Mass of the satellite
B.
Mass of the Earth
C.
Distance from the center of the Earth
D.
Speed of the satellite
Solution
The gravitational force on a satellite depends on its mass, the mass of the Earth, and the distance from the center of the Earth, but not on the speed of the satellite.
