An intake manifold gasket has been replaced due to a vacuum leak. Which of the following steps uses a scan tool to complete the job? O A. Torquing the manifold bolts B. Idle relearn O C. Refilling the cooling system O D. Air cleaner check
Answer: B.Idle relearn
Explanation:
When replacing an intake manifold gasket due to a vacuum leak, using a scan tool for idle relearn is a crucial step to complete the job. The Option B.
How does a scan tool help complete the job when replacing an intake manifold gasket?The scan tool is used to reset the idle control system and allow the engine's computer to relearn the correct idle speed and air/fuel mixture. This is important because the replacement of the intake manifold gasket can affect the engine's idle characteristics.
By using the scan tool to perform an idle relearn procedure, the engine management system can recalibrate and optimize the idle control parameters, ensuring smooth and stable idle operation. This step helps to restore the engine's performance and maintain proper combustion efficiency after the intake manifold gasket replacement.

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 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.

Declare a variable and increment with a while loop until the variable is not less than 5Create a function that returns the product of two numbersUses the new keyword to create an arraywere written in JavaScript and are found in the attached images
Declaring a variableThe first code declares a variable called num and gives it an initial value of 0. It then enters a while loop that lauches a message box (using window.alert) to print the message "Keep going" as long as num remains less than 5.
If nothing is done within the loop to increment num towards the value 5, the loop will go on endlessly notifying the user to "Keep going".
So, an increment of 1 was added to the loop body to increment the variable num. This makes sure the loop terminates.
Creating a function that returns the product of two numbersHere, a function was created that receives two arguments (n1 and n2), then returns the product (n1 * n2)
Declaring an ArrayThis last code segment creates an array using the new keyword. The new keyword is generally used in constructing objects.
In this case the object constructed is an array having three strings;

A 100 MHz generator with Vg= 10/00 v and internal resistance 50 ohms air line that is 3.6m and terminated in a 25+j25 ohm load
The value of Vz at point z from the generator = 17.748 ∠ -107.62° V
Given data :
Internal resistance = 50 ohms
Vg = 10 ∠ 0° v
length of air line = 3.6 m
Terminating resistance = 25 + j25 Ω
First step : Determine the Total impedance
Total Impedance ( z ) = Rin + Rline + Rl + jXl
= 50 + 50 + 25 + j25
= 125 + j25 ≈ 127.47 ∠ 11.3°
Next step : Determine the current in the circuit
current ( I ) = Vg / z
= ( 10∠0° v ) / ( 127.47 ∠ 11.3° )
= 0.0784 ∠ -11.3 amp
Final step : Determine the value of Vz at point z from the generator
Vz = ( Vg + I * Ri ) - ( RI * I + Rline * I )
= ( 10∠0° + 0.0784 ∠ -11.3 * 50 ) - ( 25 + j25 + 50 * 0.0784 ∠ -11.3 )
= -5.37 - j16.91 ≈ 17.748 ∠ -107.62° V
Hence we can conclude that the value of Vz at point z form the generator 17.748 ∠ -107.62° V

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]
