Answer» Solution :(i) `3 ms^(-2) = ((3)/(1000) km)((1)/(60xx60)HR)^(-2)` `= (3 xx (60 xx 60)^(2))/(1000) = 3.8880 xx 10^(4) "km" h^(-2) = 3.9 xx 10^(4) "km" h^(-2)` (ii) G = `6.67 xx 10^(-11) N m^(2) kg^(-2)` `= 6.67 xx 10^(-11) (kg m s^(-2)) (m^(2) kg^(-2))` `= 6.67 xx 10^(-11) kg^(-1) m^(3) s^(-2)` `= 6.67 xx 10^(-11) (1000 g)^(-1) (100 cm)^(3) (s^(-2))` `= 6.67 xx 10^(-11) xx (1)/(1000) xx 100 xx 100 xx 100 g^(-1) cm^(3) s^(-2)` `= 6.67 xx 10^(-8) g^(-1) cm^(3) s^(-2)` |
