What is the value of a monolithic capacitor with 103 on it?
- 1000pf.
- 10,000pf.
- 100,000pf.
10^3 =1000pf correct me if am wrong
What does the cut of a file refer to?
- Arrangement of the teeth.
- Number of teeth per inch.
- Grade of material used.
Please write your question here.
The lifting or flaking of the metal at the surface due to delamination of grain boundaries caused by the pressure of corrosion is
- exfoliation.
- electrolysis.
- transgranulation.
Why?
The material specifications for a certain aircraft require that a replacement oil line be fabricated from3/4 inch, 0.072 5052-0 aluminium alloy tubing. What is the inside dimension of this tubing?
- 0.688 inch.
- 0.606 inch.
- 0.750 inch.
Can someone help explain please? Thanks.
Capped nuts are used so
- to prevent leaks from pipe ends.
- the part is not over torqued as the bolt touches the captive part first.
- to ensure that it is dry bolted.
for this question the answer is part not over torqued as bolt touches the captive part first..
meanwhile for this question, the answer is to stop leak:
Capped nuts are used
• prevent overtightening due to the threaded portion being restricted by the cap.
• to provide a dry torque joint.
• to stop leaks.
care to explain anyone?
The Authorised Release Certificate EASA Form 1 can
- have several items entered onto it providing they are identical part numbers.
- have several items entered onto it of different part numbers.
- have only one item entered onto it.
i havent encounter with Form 1 with have several items entered onto it of different part numbers till date but have seen many Form 1 have several items entered onto it providing they are identical part numbers.
can anyone explain this which is correct and why?
A conductor with a positive Q (charge) of 4C has 12.56 x 1018 electrons added to it. It will have a Q =
- 6.
- 2.
- 0.
help?
Which has the greatest volume?
- 1 kg of water at 0 degreesC has a greater volume than 1 kg of ice at the same temperature.
- 1 kg of ice at 0 degreesC has a greater volume than 1 kg of water at the same temperature.
- Both 1 kg of ice at 0 degreesC and 1 kg of water at 0 degreesC have the same volume.
what exactly does this question test,attention to details i suppose.
If the outer cover of a flexible hose is found to be cracked.
- It is unserviceable due to possible flow restriction.
- It may still be serviceable.
- It is unserviceable since it may leak.
shouldnt it be unservicable?
A secondary earth is
- not less than 0.5mm.
- 18 AWG.
- 22 AWG.
i dont understand
Following a major defect the C of A
- is not affected, however may run out on a time basis.
- will be invalidated and requires a full renewal survey before flight.
- Nothing will happen and the C of A remains fully valid.
i dont undersrand the question help please.
In a diode clamper, if the resistor is removed making the time constant equal to C x r where r is the reverse resistance of the diode, this will ensure a
- long time constant.
- short time constant.
- variable time constant.
i dont understand this question can anyone plzz explain it ?
A Transformer with 115V primary voltage and a ratio of 5:1 is supplying a landing light (load 24V 45 amps) is used, what is the current drawn?
- 205 amps.
- 5 amps.
- 9 amps.
why please
In a parallel LCR circuit, if the capacitance is increased by 4 times, what happens to the impedance of the capacitor?
- Increases by 4 times.
- Remains the same.
- Decreases by 75%.
why is this happening?
The Sine wave signals of a circular time base are
- in phase.
- phase separated by 90degrees.
- phase separated by 180degrees.
guys explain kindly
Three capacitors connected in series, each having a value of 12 picofarads, calculate the total capacitance
- 36 picofarads.
- 4 picofarads.
- 12 picofarads.
i think it is 36
The secondary winding of a transformer has an impedance of 10 ohms and 1500 turns. For the primary winding to have an impedance of 1 kilohm, how many turns must it have?
- 15,000.
- 1,500,000.
- 150,000
why
In a series LCR circuit at resonance, R = 100 ohms, L and C are each 10 ohms. The total impedance is
- zero ohms.
- 100 ohms.
- 30 ohms.
why?
If the phase voltage of a star wound generator is 115V, what would be the line to line voltage?
- 220V.
- 180V.
- 200V.
why?
For the diagram shown find the voltage at point B.
- 7V
- 10V
- 26V
why?
The inlet of a turbo fan is
- divergent
- convergent
- convergent-divergent
How come?
How are the combustion chambers cooled?
- By l.p compressor air
- By h.p compressor air
- By fan pressure air
how??
The variable bleed valves on a engine at start up is
- open
- closed
- modulating
bleed valve of the engine remain open during the starting of the engine???????????????????
A thermocouple indication is taken from the
- hot junction
- cold junction
- difference between the hot junction and the cold junction
Cant understand this answer, it is suppose to be difference b/w hot and cold.please explain why only cold junction.
An aircraft flying at 800mph would typically use
- turbojet
- turbofan
- turboprop
it could be turbofan too
