The area under a velocity–time graph represents:
सही उत्तर: क) Displacement
Area under v–t graph = ∫v dt = displacement. The slope of the v–t graph (not area) gives acceleration.

A stone is dropped from a height of 80 m. The time taken to reach the ground is (g = 10 m/s²):
सही उत्तर: घ) 4 s
h = ½gt² gives t = √(2h/g) = √(160/10) = 4 s. 16 s results from forgetting the square root (2h/g = 16).

A car starts from rest and accelerates uniformly at 2 m/s² for 5 s. The distance covered is:
सही उत्तर: ख) 25 m
s = ut + ½at² = 0 + ½ × 2 × 5² = 25 m. 50 m results from forgetting the factor ½.

Which of the following is a dimensionless quantity?
सही उत्तर: क) Strain
Strain is the ratio of change in dimension to original dimension, so it has no units or dimensions. Stress, pressure and Young's modulus all have dimensions [ML⁻¹T⁻²].

The number of significant figures in 0.00450 is:
सही उत्तर: घ) 3
Leading zeros are not significant, but the trailing zero after the decimal point is significant, giving 4, 5, 0 = 3 significant figures.

-
Which pair of physical quantities has the same dimensions?
सही उत्तर: ग) Work and torque
Both work and torque have dimensions [ML²T⁻²]. However, torque is a vector while work is a scalar, so they are not the same physical quantity.

The SI unit of coefficient of viscosity is:
सही उत्तर: ख) N s m⁻²
From F = ηA(dv/dx), η = F/(A·dv/dx) which has unit N s m⁻² (i.e. Pa·s, also called poiseuille). N m⁻¹ is the unit of surface tension.

The dimensional formula of force is:
सही उत्तर: क) [MLT⁻²]
Force = mass × acceleration, so [M][LT⁻²] = [MLT⁻²]. [ML²T⁻²] is the dimension of work/energy, not force.

The value of the determinant |1 1 1; a b c; a² b² c²| is:
सही उत्तर: घ) (a − b)(b − c)(c − a)
This is the Vandermonde determinant. It vanishes whenever two of a, b, c are equal, and it equals (a − b)(b − c)(c − a). abc is wrong because the determinant need not be zero when one of the variables is zero.

The value of log₃ 5 · log₅ 27 is:
सही उत्तर: ग) 3
By change of base, log₃ 5 · log₅ 27 = log₃ 27 = 3. 1 would be the answer only for log₃ 5 · log₅ 3.
