    no here is the qurstion If you have a heat engine with a hot reservoir of 515°C and a cold reservoir of 190°C, what is the thermal efficiency of the system?

    @marieeeee did they give you any more information for this question? \[a = \frac{ V _{2}-V _{1} }{ t _{2}-t_{1} }\]

    \[v=u+at\] where v is your final velocity, u is initial velocity, t is time and a is acceleration Other equations relating a and u are \[s=ut+\frac{1}{2}at^2\] \[v^2-u^2=2as\] s is displacement

    You can clearly compare how acceleration changes when u is 0 or u has some value using any equation
