When is the output of an OR-gate LOW?​

Answers

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.

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.

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.

Answers

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 a NAND-gate HIGH?​

Answers

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.

A periodic digital waveform has a pulse width 25 and a period of 150 . Determine the frequency and the duty cycle

Answers

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%.

The volume of microbial culture is observed to increase according to the formula

Answers

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))

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?

Answers

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.
