An incrementer is a special kind of adder that takes in one input and adds 1 to it. (That is, it computes S = X + 1). Show how you can build a 4-bit incrementer using only half adders. (Remember, a half adder has two inputs and two outputs—it does not have a carry-in input.)

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

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

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
