result of mixing 10g ice at -10C with 10g water at +10C. find the temperature? when C ice= 2.1J/gC , Lf ice= 336J/gC , Cw= 4.2J/gC

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.

Properties seen when one one substance changes to another are known as properties

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).
