a Carnot engine is operated between two reservoirs at temperature 400k and 300k. If the engine receives 200J from the 400k reservoir, how many joules does it reject to the lower temperature reservoir and what is the thermal efficiency of the reservoir​

Divide 108.2 x 10^6 into 1.5 x 10 and the result will be in au (astronomical units)

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
