Question

2.8 Find dimension
i) Impulse
ii) Pressure​

Answer 1

Explanation:

Impulse = Force × Time

= kgm/s² × s

= kgm/s

= [M¹L¹T^-¹]

Pressure = Force/Area

= kgm/s²/m²

= M¹L¹T-²/L²

= [M¹L-¹T-²]

Answer 2

i) Impulse = Force × Time

$= {m}^{1} {l}^{1} {t}^{ - 2} \times {t}^{1} \\ = {m}^{1} {l}^{1} {t}^{ - 1}$

ii) Pressure = Force / Area

$= \frac{ {m}^{1} {l}^{1} {t}^{ - 2} }{ {l}^{2} } \\ = {m}^{1} {l}^{ - 1} {t}^{ - 2}$
