Answer 2

Given:

'X’ does 400 J of work in 1⁄6 hrs and ‘Y’ does 600 J of work in 1⁄3 hrs .

To find:

Ratio of power developed ?

Calculation:

• Power is defined as the rate of doing work.

• SI unit of power is watt (i.e. J/Second)

$\dfrac{P_{X}}{P_{Y}} = \dfrac{ \bigg( \dfrac{400}{1/6 \times 3600} \bigg)}{ \bigg( \dfrac{600}{1/3 \times 3600} \bigg)}$

$\implies \dfrac{P_{X}}{P_{Y}} = \dfrac{ \bigg( \dfrac{400}{1/6} \bigg)}{ \bigg( \dfrac{600}{1/3 } \bigg)}$

$\implies \dfrac{P_{X}}{P_{Y}} = \dfrac{ \bigg( \dfrac{4}{1/6} \bigg)}{ \bigg( \dfrac{6}{1/3 } \bigg)}$

$\implies \dfrac{P_{X}}{P_{Y}} = \dfrac{ 4 \times 6}{ 6 \times 3}$

$\implies \dfrac{P_{X}}{P_{Y}} = \dfrac{ 4 }{ 3}$

So, required ratio is 4 : 3 .
