Question

Give name of scalar and vector quantity which have same dimensions

Answer 1

______here is ur answer_____
Planck constant(scalar quantity) has same dimensions as linear momentum(vector quantity)
linear momentum=r×p
p=mv=kgm/s
linear momentum=m×kgm/s
linear momentum=kgm^2/s
while E=hf
h=E/f
h=kgm^2/s^2×s
h=kgm^2/s
work is a vector quantity while energy is scalar quantity.
W=F.S
W=N.m
W=kgm/s^2.m
W=kgm^2/s^2
E=mv^2
E=kgm^2/s^2
so both energy and work have same dimensions
