Which of the following statements is correct? assume that the project being considered has normal cash flows, with one outflow followed by a series of inflows. a) the higher the wacc used to calculate the npv, the lower the calculated npv will be. b) if a project's npv is greater than zero, then its irr must be less than the wacc. c) if a project's npv is greater than zero, then its irr must be less than zero. d) the npvs of relatively risky projects should be found using relatively low waccs.

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a.if the manual switch s is on, then the light l is on. b.besides the manual switch, there is a motion detector, m1, which activatesthis light.c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d.the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
