The resistance of a starter for a 200-V, shunt motor is such that maximum starting current is 30 A. When the current has decreased to 24 A, the starter arm is moved from the first to the second stud. Calculate the resistance between these two studs if the maximum current in the second stud is 34 A. The armature resistance of the motor is 0.4 Ω.
ANSWER [1.334 Ω]

We have created an ArrayList of Person class. write a method called push that pushes all the people with the even length last name to the end of the ArrayList
Content of the ArrayList before push
[alex Bus, Mary Phillips, Nik Lambard, Rose Rodd, Esa khan, Jose Martinex, Nik Patte]
content of the ArrayList after the push method
[alex Bus, Nik Lambard, Nik Patte, Mary Phillips, Rose Rodd, Esa
khan, Jose Martinex]
