41)Option B [Always equal to 1]

42)Option C [2r]

The displacement is the minimum distance between the initial position and final position.

Suppose a particle starts at a point A at the periphery of the circle and after covering half the circle, particle is at point B.

The minimum distance between points A and B is AB which is also the diameter of the circle.

Therefore, displacement after covering half the circle =Diameter=2r

43)Option B[meter]

44)Option C[Always equal and opposite]

45)Option C

Force = 250N

Acceleration = 5m/s²

Mass = m = ?

We know that,

Force = Mass × Acceleration

F = ma

Hence

m = F/a

m = 250/5

m = 50kg

Therefore the correct option is option (C)250kg

46)Option B [N's second law]

47)Option C [It always goes away from the earth]

48)Option B[Always equal and opposite]

49)Option B[Car B slows]

The slope of distance vs time graphs represent speed. B has the minimum slope and hence the minimum speed.
