Question

a truck moves at the speed of 36 kilometre per hour or how far will it travel in 15 seconds​

Answer 1

Step-by-step explanation:

The NAND (Not – AND) gate has an output that is normally at logic level “1” and only goes “LOW” to logic level “0” when ALL of its inputs are at logic level “1”. The Logic NAND Gate is the reverse or “Complementary” form of the AND gate we have seen previously.

Logic NAND Gate Equivalence

logic nand gate

The logic or Boolean expression given for a logic NAND gate is that for Logical Addition, which is the opposite to the AND gate, and which it performs on the complements of the inputs. The Boolean expression for a logic NAND gate is denoted by a single dot or full stop symbol, ( . ) with a line or Overline, ( ‾‾ ) over the expression to signify the NOT or logical negation of the NAND gate giving us the Boolean expression of: A.B = Q.

Then we can define the operation of a 2-input digital logic NAND gate as being:

Answer 2

speed = distance / time

distance= 36000× 15seconds

= 5,40,000 m/s

= 540km
