Find an article written in the last year that describes the problem and proposes some solutions. Try searching for terms such as “environmental disaster,” “oil spill,” “groundwater contamination,” “air pollutants,” or other terms of your choosing. Focus your search on reputable news sources. The article may be from a website, newspaper, magazine, or other online source. The article may not be from a blog, unless it is a U. S. government site.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

An electric kettle is made out of stainless steel, weighs two pounds (when empty) and is equipped with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
