[" Q.6Efficiency of engine is "eta_(1)" at "T_(1)=200^(@)C" and "T_(2)=0^(@)C" and "eta_(2)" at "T_(1)=0^(@)C" and "T_(2)=200K" ."],[" the ratio of "(eta_(1))/(eta_(2))]

Efficiency of an engine is eta1 at T1 =200 degree C and T2= 0 degree C and eta2 at T1 = 0 degree C and T2 = -200 degreeC find the ratio of eta1 / eta2

In a Carnot engine when T_(2) = 0^(@)C and T_(1) = 200^(@)C its efficiency is eta_(1) and when T_(1) = 0^(@)C and T_(2) = -200^(@)C . Its efficiency is eta_(2) , then what is eta_(1)//eta_(2) ?

In a Carnot engine when T_(2) = 0^(@)C and T_(1) = 200^(@)C its efficiency is eta_(1) and when T_(1) = 0^(@)C and T_(2) = -200^(@)C . Its efficiency is eta_(2) , then what is eta_(1)//eta_(2) ?

In a Carnot engine when T_(2) = 0^(@)C and T_(1) = 200^(@)C its efficiency is eta_(1) and when T_(1) = 0^(@)C and T_(2) = -200^(@)C . Its efficiency is eta_(2) , then what is eta_(1)//eta_(2) ?

The efficiency of d.c. motor is given by eta =
