Thermal Efficiency: Qincap Q sub i n end-sub is only the positive heat absorbed by the system. Step-by-Step Solution Calculate Total Net Work ( Wnetcap W sub n e t end-sub ): The path forms a triangle with base and height Analyze Heat Input ( Qincap Q sub i n end-sub ): Process 1 →right arrow 2 (Constant Volume, Isochoric): , Pressure goes from P0cap P sub 0 2P02 cap P sub 0 (Heat is absorbed). Process 2 →right arrow 3 (Linear Path): From

The observed rotation curves of spiral galaxies (velocity vs. radius) remain flat or even rise at large radii, while Keplerian motion predicts a decline ($v \propto r^-1/2$). Explain this discrepancy and show how it leads to the dark matter hypothesis.

Why do elliptical galaxies have much larger $M/L$ ratios than spiral disks? What does this imply about their formation?

Let the acceleration of the wedge be

Galaxy mergers can lead to the formation of a new, more massive galaxy, with a changed structure and composition. The merger can trigger starbursts, and the resulting galaxy may have a different shape, size, and stellar population.
