Explanation:
The question is basically asking you to build a 2-bit asynchronous counter.
What the counter does is it increase it's value by 01₂ every clock pulse. So at 0₂, nothing happens, but at 1₂ it'll count up by 1. It then reset to 00₂ when it overflows.
The design for it is pretty much universal so I kinda did this from memory.
a.) A count-up counter (from 00-11) is simply made by connecting Q' to D, and the output of the previous DFF to the clock of the next one.
b.) A count-down counter (from 11-00) is simply made by using the same circuit as the count-up counter, but you connect Q' to the clock instead of Q.
Answer:
Rate of corrosion = 24.95 mpy
Rate of corrosion = 0.63 mm/yr
Explanation:
given data
steel sheet area = 150 in²
weight loss = 485 g
density of steel = 7.9 g/cm³
time taken = 1 year
to find out
rate of corrosion in (a) mpy and (b) mm/yr
solution
we get here the rate of corrosion that is express as
rate of corrosion = (k × W) ÷ (D × A × T) ..................1
here k is constant and w is total weight lost and t is time taken for loss and A is surface area and D is density of steel
so put her value in equation 1 we get
Rate of corrosion = 
Rate of corrosion = 24.95 mpy
and
Rate of corrosion = 
Rate of corrosion = 0.63 mm/yr
Answer:
b)false
Explanation:
As we know that
Volume flow rate Q
Q = A x V
For constant volume flow rate,if velocity will increase then automatically area will decrease and vice versa.
Generally nozzle are used to increase the velocity and diffuser are used to decrease the exit velocity of flow.
So by increasing the cross sectional area of the restriction ,the velocity of the flow will decrease.
Answer:
Below see details
Explanation:
A) It is attached. Please see the picture
B) First to calculate the overall mean,
μ=65∗25/75+80∗25/75+95∗25/75
μ=65∗25/75+80∗25/75+95∗25/75 = 80
Next to calculate E(MSTR) = σ2+(1/r−1) ∑ni(μi−μ)^2 = 5634
And E(MSE) = σ^2= 9
C) Yes, it is substantially large than E(MSE) in this case.
D) If we sampled 25 employees from each group, we are likely to get a F statistics to indicate differences of job satisfactions among three types of length of service of employees.
