Answer 2

Q. Name the physical quantities whose dimensions are 1)ML^2T^-22)ML^2T^-33)MT^-24)ML^-1T^-15)ML^-1T^-2

Ans:-

1) Work

2)Power

3)Surface tension

4)Coefficent of viscosity

5)Pressure or Stress

Explanation:-

$(1) \: \: m {l}^{2} {t}^{ - 3}$

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

$= force \times distance$

$= work$

$(2) \: \: m {l}^{2} {t}^{ - 3}$

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

$= \frac{work}{time}$

$= power$

$(3) \: \: m {t}^{ - 2}$

$= \frac{ml {t}^{ - 2} }{l}$

$= \frac{force}{length}$

$= surface \: tension$

$(4) \: \: m {l}^{ - 1} {t}^{ - 1}$

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

$= \frac{force}{area \times velocity \: gradeint}$

$= coefficent \: of \: viscocity$

$(5) \: \: m {l}^{ - 1} {t}^{ - 2}$

$= \frac{ml {t}^{ - 2} }{ {l}^{2} }$

$= \frac{force}{area}$

$= pressure \: or \: strain \:$
