Question

obtained the dimensions of the following SI derived quantities from their defining equations i) density ii) momentum​

Answer 1

Answer:

Density is dimensionally represented as [M1 L-3 T0].

Momentum is dimensionally represented as [M1 L1 T-1].

Answer 2

Explanation:

density = mass / volume

dimension of mass / dimension of volume

[M]/[L³] = [ML^(-3)]

like this

momentum P = mv

[M] / [LT^(-1)] = [MLT^(-1)]
