You are using a wrench in an attempt to loosen a nut by applying
a force as shown; but this fails to loosen the nut. Which one of
the following choices is most likely to loosen this tough nut?
Select all that apply.
Doubling the length or doubling the force will have the same
result, but doubling the length is easier.
Continue applying the same force as in the drawing and
eventually the nut will loosen.

Consider an 8 to 256 decoder built using 256 8-input AND gates. 1. For the decimal input A=65, 0x41, how many inverters will be used with the 8-input AND gate used to perform a successful decode of A? 2. Numbering the eight AND gate inputs a7 through a0, a7..a0, with a7 associated with the most significant bit of the input A and a0 associated with the least significant bit, list the inputs in descending order that will have an inverter...
