Best Science GK Questions for SSC Exams
Q : Consider an inductor whose linear dimensions are tripled and the total number of turns per unit length is kept constant, what happens to the self-inductance?
(A) 9 times
(B) 3 times
(C) 27 times
(D) 1/3 times
Correct Answer : B
What is the constant of proportionality of an oscillator if the damping force is directly proportional to the velocity
(A) Kg.s-1
(B) Kg.m.s-1
(C) Kg.s
(D) Kg.m.s-2
Correct Answer : A
Explanation :
The damping force of an oscillating particle is observed to be proportional to velocity. The constant of proportionality can be measured in. kgs−1.
The capacity of parallel plate condenser is dependent on the
(A) The separation between the plates
(B) The metal used for the construction
(C) The thickness of the plate
(D) The potential applied across the plates
Correct Answer : B
Explanation :
Therefore, the capacity of a parallel plate capacitor directly depends on the relative permittivity of dielectric material, the permittivity of space, the area of plates, and is inversely dependent on the separation between the plates.
The observer hears a sound from the source which is moving away from the observer who is stationary. Determine the frequency of the sound
(A) It is halved
(B) It remains the same
(C) It reaches infinity
(D) It gets doubled
Correct Answer : A
Explanation :
If the observer is moving away from the source ((Figure)), the observed frequency can be found: λs=vTo−voTovTs=(v−vo)Tov(1fs)=(v−vo)(1fo)fo=fs(v−vov).
Find the molecular mass of a gas that takes three times more time to effuse as compared to He with the same volume
(A) 9 u
(B) 64 u
(C) 27 u
(D) 36 u
Correct Answer : B
Explanation :
Its molecular mass will be: 64u.
What is the ratio of power dissipated if two electric bulbs are connected in series and the ratio of their resistance is 1:2?
(A) 1:4
(B) 1:2
(C) 2:1
(D) 1:1
Correct Answer : B
Consider copper and aluminum wire whose length and resistance are the same. Also, the specific resistance of aluminum is more than copper. Select the correct statement
(A) Copper and aluminum mass are the same
(B) Copper wire has more mass than the aluminum wire
(C) Copper wire has less mass than the aluminum wire
(D) The information given is incomplete
Correct Answer : D
A potentiometer is considered a versatile and accurate device to make an electrical measurement of EMF. Why?
(A) Because the method involves a combination
(B) There are cells involved
(C) Because of potential gradients
(D) As there is no flow of current through the galvanometer
Correct Answer : D
Explanation :
A potentiometer is an accurate and versatile device to make electrical measurements of emf because the method involves a condition of no current flow through the galvanometer, the device can be used to measure potential difference, internal resistance of a cell and compare emf's of two sources. Q.
Degree of dissociation does not depend on which of the following factors?
(A) Nature of the solute
(B) Nature of the solvent
(C) Sound
(D) Concentration
Correct Answer : C
Explanation :
The Degree of dissociation does not depend on catalyst.The equivalent conductivity of 0.1M weak acid is 100 times less than that at infinite dilution.
What is the degree of dissociation for strong electrolytes?
(A) 1
(B) 0
(C) Less than 1
(D) Greater than 1
Correct Answer : A
Explanation :
Strong electrolytes have a degree of dissociation close to one, while weak electrolytes have a degree of dissociation less than one. Solvent nature: Solvents with a high dielectric constant show more dissociation. Dilution: As the solution is diluted, the degree of dissociation increases.
