xT: R1← R1+ R2
x' T: R1 ← R2
Every time that variable T = 1, either the content of R2 is added to the content of Rl if
x = 1, or the content of R2 is transferred to R1 if x = 0. Draw a diagram showing the
hardware implementation of the two statements. Use block diagrams for the two 4-bit
registers, a 4-bit adder, and a quadruple 2-to-1-llne multiplexer that selects the inputs
to R l . In the diagram, show how the control variables x and T select the inputs of the
multiplexer and the load input of register R1.
fk (0, 0) = fk (0, 1) = fk (1, 1) = 1; fk (1, 0) = 0
Assuming complements of A and B are not available, what will be the minimum cost
solution for realizing using only 2-input NOR gates and 2-input OR gates (each
having unit cost) ? Explain with nessessary digram and expression.
A truck proceeds to be able to pass another truck. Its speed increases from 50 to 100 km/h in 4 seconds. What is its average acceleration?
Two runners are competing in a 400-meter dash. The first run at 6 m/s and maintains this speed. The second runner starts at 10 m/s and decelerates at 1/8 m/s2. Who will finish first? What will be their time difference?

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
