Question

show that the following pairs of physical quantities have identical dimension​

Answer 1

Answer:

(A) : Young's modulus is given by Y= AF . LΔL This implies Pressure (F/A) and Young's modulus have same dimensions. (B) : From the equation L= 2πnh We say that, Planck's constant and angular momentum have same dimensions.(C) : Using the relation between impulse J and moment of force τ, J=τΔtWe say that impulse and moment of force have different dimensions.(D) :From the relation F= dtdd

We say that force F and rate of change of momentum

We say that force F and rate of change of momentum dt

dp

have same dimension
