A periodic digital waveform has a pulse width 25 and a period of 150 . Determine the frequency and the duty cycle
The frequency is 6.67 kHz and the duty cycle is:16.67%.
Frequency and duty cycle
Given:
Pulse width=25
Period=150
Frequency:
Frequency=1/(150×10^-6)
Frequency=1/0.00015
Frequency=6.666 kHz
Frequency=6.67 kHz (Approximately)
Duty cycle:
Duty cycle=(25×10^-6)/ (150×10^-6)×100%
Duty cycle=16.67%
Therefore the frequency is 6.67 kHz and the duty cycle is:16.67%.

When is the output of a NAND-gate HIGH?
Answer:
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.

Technician A says that primary vibration is created by slight differences in the inertia of the pistons between top dead center and bottom dead center. Technician B says that secondary vibration is a strong low-frequency vibration caused by the movement of the piston traveling up and down the cylinder. Who is correct? O A. Neither Technician A nor B OB. Technician B O C. Both Technicians A and B D. Technician A
Neither technician Technician or B is correct in the statement above.
What leads to primary vibration?Vibration is a factor that is said to be caused by one or more other factors that occur together at any given time.
This can be due to actors such as imbalance, misalignment, wear and looseness and others. An imbalance occurs due to a "heavy spot" that is found inside a rotating component and it will lead to vibration when the unbalanced weight is said to rotates in circles round the machine's axis.

Determine the mass density of an oil if 0.3 tonnes of the oil occupies a volume of 4m.
Answer:
Do you mean 4m^3 and 3.0 tones?
Explanation:
solution:
Mass = m = 3.0 tones
- 1 ton = 1,000 kg
= 3.0 × 1,000
= 3,000 kg
volume = v = 4m^3
Required:
Mass density of oil = p = ?
We know that;
[tex]p = \frac{mass}{volume} = \frac{m}{v} = \frac{3000}{4} = 750kg |m^{3} ans [/tex]
The answer is:
750kg / m^3

When is the output of an OR-gate LOW?
Answer:
The OR gate is a digital logic gate that implements logical disjunction (∨) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.

A student borrows $60,000 for business school at 6.5% stated annual interest with equal monthly payments over 10 years. Consider this as a loan with no payments or interest during school so that the problem structure is equivalent to a standard loan received one period before the first payment. How much is the monthly payment?
Answer:
$681.29
Explanation:
The amortization formula seems to apply. The monthly payment on a loan of P at rate r for t years is ...
A = P(r/10)/(1 -(1 +r/12)^(-12t))
For the given loan parameters, the monthly payment is ...
A = $60,000(0.065/12)/(1 -(1 +0.065/12)^(-12·10)) ≈ $681.29
The monthly payment is $681.29.

The volume of microbial culture is observed to increase according to the formula
V(m^3)=e^t
where t is time in seconds
a,calculate the expression for V(in^3) in terms of t(minute)
b,
The expression of V(m³)=e^(t(s)) to make V in in³ and t in minutes is;
V(in³) = (¹/₆₁₀₂₄)a[tex]e^{\frac{1}{60}bt(h)[/tex]
We are given that;
Volume of microbial culture is observed to increase according to the formula;
V = e^(t)
where;
t is in seconds
V is in m³
We want to now express V in in³ and t in minutes.
Now, from conversions;
1 m³ = 61024 in³
Also; 1 second = 1/60 minutes
according to formula for exponential decay, we know that;
V = ae^(bt)
Thus, we have;
61024V = ae^(¹/₆₀b(t(h))
V(in³) = (¹/₆₁₀₂₄)a[tex]e^{\frac{1}{60}bt(h)[/tex]

In a modern industrial plant the most likely polyphase power system in use is a/an blank system
Answer:
three-phase
Explanation:
2-phase, 3-phase, and 6-phase systems are in use. The most common of these is 3-phase.
A modern industrial plant most likely uses a 3-phase system.

Additional comment
Serious research began on 6-phase power transmission systems in 1973. They have been shown to increase power transfer, and to reduce corona, magnetic fields, and audio noise compared to 3-phase systems. However, they are not in widespread industrial use.
