Convert (i) `1Nm^(2)kg^(-2)` into dyne `cm^(2)g^(-2)`, (ii) `60Kmhr^(-1)` into `ms^(-1)`,

Text Solution

Verified by Experts

The correct Answer is:
(i) `10^(3)` (ii) `16.67ms^(-1)`
`1N=10^(5)` dyne `1kg=10^(3)g,1m=10^(2)m`
`1Nm^(2)kg^(-2)=10^(5)` dyne `xx(10^(2)cm)^(2)xx(10^(3)g)^(-2)=10^(3)"dyne"cm^(2)g^(-2)`
(ii) `60kmh^(-1)=60xx1000mxx(3600)^(-1)s^(-1)=16.57ms^(-1)`
