A production plant has a requirement for a counter that will count 4,000 items before recycling and starting over. How many D fl

ip-flop stages would be required in this counter

6 0

Answer:

12

Explanation:

A n-bit integer represents values from 0 to (2^n)-1 states. For example, if we have 3 bits we can count up to 7 states, that is counting from 0 to 7.

On the other hand, a flip flop stores one bit of data  So, we will need n flip flops to count (2^n) -1 states.

So we have production plant that requires a counter that will count 4,000 items before recycling and starting over.

Therefore (2^n) - 1 =4000. The nearest integer value of n that will give 4000 is 12.

For n = 12 , 2^12 = 4096 and for n =11 2^11 = 2048. 12 is the closest value. Therefore we need 12 D Flip Flop stages to count the required items.

Bingel [31]

Answer:

None of these is correct.

Explanation:

The wave particle duality has to do with Louis de Broglie's proposition that matter could exist as waves or particles.

According to him, matter poseses an associated wavelength. Hence, a certain wavelength is traceable to the hydrogen atom.

This wavelength is the ratio of Plank's constant to the momentum of the hydrogen atom

How do scientists and engineers use math to help them?
VikaD [51]
Math (e.g., algebra, geometry, calculus, computer computation) is used both as a tool to create mathematical models that describe physical phenomena and as a tool to evaluate the merit of different possible solutions. ... In engineering, math and science are tools used within the engineering design process.
Biologists use math as they plot graphs to help them understand equations, run small “trial and error” tests with some sample numbers when developing algorithms, and use the R project for analyzing protein sequences and structures. Electrical engineers use math in many ways in their career. They use math to help design and test electrical equipment. They use math to calculate amp and volt requirements for electrical projects. They use math in creating computer simulations and designs for new products.

gregori [183]

Answer:

(a) T = W/2(1-tanθ)  (b) 39.81°

Explanation:

(a) The equation for tension (T) can be derived by considering the summation of moment in the clockwise direction. Thus:

Summation of moment in clockwise direction is equivalent to zero. Therefore,

T*l*(sinθ) + W*(l/2)*cosθ - T*l*cosθ = 0

T*l*(cosθ - sinθ) = W*(l/2)*cosθ

T = W*cosθ/2(cosθ - sinθ)

Dividing both the numerator and denominator by cosθ, we have:

T = [W*cosθ/cosθ]/2[(cosθ - sinθ)/cosθ] = W/2(1-tanθ)

(b) If T = 3W, then:

3W = W/2(1-tanθ),

Further simplification and rearrangement lead to:

1 - tanθ = 1/6

tanθ = 1 - (1/6) = 5/6

θ = tan^(-1) 5/6 = 39.81°
