The compression ratio of an Otto cycle as shown in the figure below is VA/VB = 6.00. At the beginning A of the compression process, 525 cm3 of gas is at 110 kPa and 20.0°C. At the beginning of the adiabatic expansion, the temperature is TC = 730°C. Model the working fluid as an ideal gas with γ = 1.40.

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
