Answer:
The output for NAND gate is false if all the inputs are true. it is true if either A or B is False.
Step-by-step explanation:
Step1
NAND operator:
NAND is a logic or Boolean expression and is a combination of NOT and AND Gate.
NAND gate is built using various junction diodes and transistors.
Step2
The output of NAND can be 0 or 1. Here, LOW (0) and HIGH (1). 0 or 1 is commonly named as FALSE or TRUE respectively.
It is basically the complement of AND gate. If all its inputs are True or 1, then the output is False or 0 else if either A or B is 0 or 1 then it will give the output as TRUE.
Step3
Here, A and B are 2 inputs used to make the truth table for NAND.
In 1st row, when A and B are both 0, the output for NAND is 1.
Likewise, in 2st row and 3rd row, when either A or B is 0 or 1, the output for NAND is 1 that is TRUE.
But in last row, when both inputs A and B are true, then the output for NAND gate is FALSE or 0.
The diagram and truth table for NAND is shown below.
Answer:
4.9
Step-by-step explanation:
Use the butterfly method.
13*13 = 8*u
39 = 8u
(divide by 8)
4.875 = u
4.875 is about 4.9
Graph 0,20 then add 0.5, or half to it after
Have a great day!
Answer:
V = M/D
Step-by-step explanation:
D = Density
M = mass
V = Volume
Volume for Density:
D = M/V
If we want to find volume we just rearrange the equation:
V = M/D
We can plug in the numbers to check whether or not this equation is true. Say we need to find density and the volumes & mass are already given (V=5 cm^3 and M=10g)
So, 10g/5cm^3 = D
2g/cm^3 = Density
Using the following numbers we can now find the Volume. Say we don't know that 5cm^3 is the volume and we are only given the Density (2g/cm^3) and Mass (10g). We plug those values into the equation V=M/D:
V = 10g/2g/cm^3
V = 5cm^3
The grams cancel out and we are only left with the cm^3 part.
Hope that explains it :)
