In the verification of ohm's law mass is 200 g initial length is 31 final length is 31.6 so what is the extension?

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Agas mixture with a compostion of 55 methane, 30% propane, and 15 butane by volume) is compressed from 1 bar and 25°c to 9bar in a compressor with an isentropic efficiency of 85%. the environment has a temperature of to25 c. determine (a) the exit temperature of the mixture (b) the specific work required to run the compressor (c) the specific entropy generation of the process (d) the specific exergy destruction of the process (e) the second law efficiency of the compressor

Through changes in clamping, a sheet-metal forming operation can allow the material to undergo a negative minor strain in the forming limit diagram. explain how this effect can be advantageous.
