The magnitude of a physical quantity is 8.5 Ns. The physical quantity ...
The newton second (also newton-second, symbol N s or N·s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram metre per second (kg·m/s). One newton second corresponds to a one-newton force applied for one second. Derivation- p=mv =kg×m/s =kgm/s×s/s =kgm/s^2×s =N×s

The magnitude of a physical quantity is 8.5 Ns. The physical quantity ...
Explanation:
Therefore, option 'B' is the correct answer.
- The physical quantity with the magnitude of 8.5 Ns is momentum.
- Momentum is the product of an object's mass and velocity. It is a vector quantity as it has both magnitude and direction.
- The SI unit of momentum is kg m/s.
- In this case, the magnitude of momentum is given as 8.5 Ns, which can be written as 8.5 kg m/s.
- Hence, the physical quantity with the magnitude of 8.5 Ns is momentum.
Therefore, option 'B' is the correct answer.
