Adding numbers victor ha an array of size n. He loves to play with these n numbers each numbers. Plays with them he pics up any two consecutive numbers and adds them on adding both numbers it costs him k*(sum of both numbers) find all minimum cost of adding all the numbers in the array. Input1:size of array,
Input2:element of the array
Input3:value of K

A copper wire of unknown length has a diameter of 0.25 in. and a resistance of 0.28 ohm. By several successive passes through drawing dies the diameter of the wire is reduced to 0.05 in. Assuming that the resistivity of the copper remains unchanged in the drawing process, calculate the resistance of the of the reduced-size wire
A 4 m long ladder is supported by a wall and floor as shown in Figure. The coefficient of friction at the wall is 0.30 and that the floor is 0.50. The weight of the ladder is 200 N. The ladder supports a vertical load of 800 N at C. Solve for the reactions at the floor and wall. Compute the least value of at which the ladder may be placed without slipping.
A single layer of No. 24 WGA (dia=0.0201) commercial iron wire is wound over a ceramic tube whose diameter is 3.25 in if the total wire resistance is 41 ohms, determine the number of turns.
