Write a static method called flip2 that takes an arraylist of strings as a parameter and then flips each successive pair of values in the list. for example, suppose that a variable called list stores the following sequence of values: ["aa", "bb", "cc", "ddd", "happy", "snow"] and we make the following call: flip(list);

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
