Question

ML⁻¹T⁻² are not the dimensions of
a stress
b tension
c energy density
d pressure

Answer 1

Answer:

b

Explanation:

Stress = force/area = MLT⁻²/L² = ML⁻¹T⁻²

Tension = force = MLT⁻²

Energy density = energy/volume = ML²T⁻²/L³ = ML⁻¹T⁻²

Pressure = force/area = MLT⁻²/L² = ML⁻¹T⁻²

From this we can see that tension does not have the same dimensions as ML⁻¹T⁻², so answer is b.

Answer 2

Answer:

b tension is the answer
