An Unkindness of Ravens An Unkindness of Ravens An Unkindness of Ravens is a novel by British crime-writer Ruth Rendell. It was first published in 1985, and features her popular protagonist Inspector Wexford, and is the 13th entry in the series. On American publication, it was shortlisted for the MWA Edgar Award, alongside another Rendell novel, "The Tree of Hands", meaning she has the remarkable distinction of being one of only two authors in the award's history to have had "two" novels on the shortlist in any one year (the other being Charlotte Armstrong). "Ravens" was adapted as a play by theatre professor Joel
Specific force acceleration. The g-force acceleration is the same as the specific force. The acceleration of an object free falling towards the earth depends on the reference frame (it disappears in the free-fall frame, also called the inertial frame), but any g-force "acceleration" will be present in all frames. This specific force is zero for freely-falling objects, since gravity acting alone does not produce g-forces or specific forces. Accelerometers on the surface of the Earth measure a constant 9.8 m/s^2 even when they are not accelerating (that is, when they do not undergo coordinate acceleration). This is because accelerometers measure the proper
