Viscoelasticity and the non-linear rheology of polymers are responsible for phenomena such as rod climbing or die swell as well as part of the challenge of processing polymer melts. 1) explain why from a polymer physics point of view polymer melts can have non-Newtonian behaviors that do not scale linearly with molecular weight and 2) explain what one of these two examples are and posit an explanation for it.

Given is the rod of length L with the linear charge of density ?=?/? . The rod lies on the x axis with its midpoint at the origin. Find the electric field vector on y axis resulting from such continuous system of charge at distance y from the origin. Use this result to obtain the expression for electric field at distance y from the infinitely long wire.

As shown in the figure, a conducting rod with a linear mass density of 0.0395 kg/m is suspended by two flexible wires of negligible mass in a uniform magnetic field directed into the page. A power supply is used to send a current through the rod such that the tension in the support wires is zero. (a) If the magnitude of the magnetic field is 3.70 T, determine the current in the conducting rod. (b) Determine the direction of the...

NO WIKI or PLAGIARIZING!! Reflect on the concepts of linear and non-linear systems. What concepts (only the names) did you need to accommodate the concept of linear and non-linear systems in your mind? What are the simplest linear system and non-linear system you can imagine? In your day to day, is there any occurring fact that can be interpreted as linear systems and non-linear systems? What strategy are you using to get the graph of linear systems and non-linear systems?
