Write a method stutter that takes an arraylist of strings and an integer k as parameters and that replaces every string with k copies of that string. for example, if the list stores the values ["how", "are", "you? "] before the method is called and k is 4, it should store the values ["how", "how", "how", "how", "are", "are", "are", "are", "you? ", "you? ", "you? ", "you? "] after the method finishes executing. if k is 0 or negative, the list should be empty after the call.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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
