A space probe is built with a mass of 2135 pound-mass [] before launch on Earth. The probe is powered by four ion thrusters, each capable of generating 185.8 millinewtons [] of thrust. What is the acceleration of the craft in feet per minute squared [ft / (mi * n ^ 2)]

On a average work day more than work place firs are reorted

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
