Convert 1 J of energy in terms of ...

Convert 1 J of energy in terms of ergs.

Text Solution

Verified by Experts

[SI unit of energy ] = x [CGS unit of energy ]
but [energy ] = ` [M^1L^2T^( -2) ]`
i.e., ` x = (["SIU of energy" ]) /(["CGSU of energy"] ) = ( 1 kg xx 1 m ^ 2 xx 1 s ^( -2))/( 1 g xx 1 cm ^ 2 xx 1 s ^( -2)) = (1000 g xx (100) ^ 2 cm ^ 2 ) /( 1 g xx 1 cm ^ 2 ) `
` x = 10 ^( 7) `
hence ` 1 J = 10 ^( 7) ` ergs
