Question

assertion: both have dimensions of length. reason: mass and density cannot be added.​

Answer 1

Answer:

Work and torque both are represented as force multiplied by distance therefore must have the same dimensional formula.

Angular momentum can be written as L=mvr which gives its dimensions i.e. kg m

2

s

−1

and it is same as that of plank's constant.

As we know E=hν

∴ h=E/ν

However tension which is defined as force and surface tension which is defined as force per unit length must have different dimensional formulas.

Impulse is change is linear momentum over a time interval, therefore has the same dimension as the linear momentum.
