Required information The PV diagram shown is for a heat engine that uses 1.030 mol of a diatomic ideal gas as its working substance. In the constant-temperature processes A and C, the gas is in contact with reservoirs at temperatures 373 K and 273 K, respectively. In constant-volume process B, the gas temperature decreases as heat flows into the cold reservoir. In constant- volume process D, the gas temperature increases as heat flows from the hot reservoir.

A 190-g block is launched by compressing a spring of constant k = = 200 N/m by 15 cm. The spring is mounted horizontally, and the surface directly under it is frictionless. But beyond the equilibrium position of the spring end, the surface has frictional coefficient μ = 0.27. This frictional surface extends 85 cm, fol- lowed by a frictionless curved rise, as shown in Fig. 7.21. After it's launched, where does the block finally come to rest? Measure from the left end of the frictional zone. Frictionless μ = 0.27 Frictionless FIGURE 7.21 Problem 57arrow_forward3.
