Question

find the value of 10 joules on a system which has 10 cm 100 g and 30s as the fundamental units ​

Answer 1

Answer:

Energy = (1/2)mv2

so E is proportional to mv2

E = 10 J = 10 Kg (m/s)2

10 J = 10 Kg (m/s)2 = 10 x 1000 g x (100 cm /s)2

= 10 x 10 x (100g) x (10 x 10 cm / s)2

= 100 x (100g) x (10x30 x 10cm/30s)2

= 100 x (100g) x (300 x 10cm/30s)2

= 100 x (300)2 x (100g) (10cm/30s)2

= 9000000 x 100g (10 cm / 30s)2

= 9000000 new unit
