1.

The unit `J Pa^(-1)` is equivalent toA. `m^(3)`B. `cm^(3)`C. `dm^(3)`D. None of these

Answer» Correct Answer - A
`Jpa^(-1)`, unit of work is Joule and unit of pressure is Pascal. Dimension of Joule i.e. work `=FxxL=MLT^(-1) xxL`
`=[ML^(2) T^(-2)]`
`L^(2)/(MLT^(-2))=M^(-1) LT^(2)`
`ML^(2)T^(-2)xxM^(-1)LT^(2)=L^(3)`
