Answer 1

Explanation:

The efficiency of carnot engine when source temperature The length of a metal is ????₁ when the tension in it is T₁ and

is ????₂ when the tension is T₂. The original length of the wire

is

(a)????₁ + ????₂/2

(b)????₁T₂ + ????₂T₁/T₁ + T₂

(c)????₁T₂ + ????₂T₁/T₂ - T₁

(d) √T₁T₂????₁????₂

is T₁ and sink temperature is T2 will be

(a) T₁ - T₂/T₁

(b) T₂ - T₁/T₂ (c) T₁ - T₂/T₂

(d)T₁/T₂
