Find the value 15 joule in a system which has 10 cm, 100 gm and 20sec

1.	Find the value 15 joule in a system which has 10 cm, 100 gm and 20sec as a fundamental units?
Answer» Solution :In S.I. `n_(1)=15, M_(1)=1KG, L_(1)=1m, T_(1)=1`s Energy `=ML^(2)T^(-2),x=1,y=2,z=-2` In the NEW SYSTEM `n_(2)=?,M_(2)=100g, L_(2)=10cm,T_(2)=20s` `n_(2)=n_(1)(M_(1)//M_(2))^(x)(L_(1)//L_(2))^(y)(T_(1)//T_(2))^(z)=15(10^(3)g//100g)^(1)(100cm//10cm)^(2)(15//20s)^(-2)` `1J=6xx10^(6)` new UNITS.
