Material A and material B are both removed from the same oven at the same time, after being in the same amount of time. Material A is a higher temperature than material B. This is because
- material B has a higher specific heat capacity.
- material A had a higher initial oven temperature.
- material A has a higher specific heat capacity.
why ?
How far does a wheel of 7m radius travel in one revolution?
- 14m
- 22m
- 44m
2 pgreck r=14pgrek. So is 43.96!!!!
Common aircraft fibreoptics use
- modulating intensity on direct read.
- modulating frequency on direct read.
- modulating phase on direct read.
please give some reference.
A pilot requests 9.2 tonnes of fuel. The bowser driver reports to the pilot that the specific gravity is 0.8, what will the uplift be?
- 10200 litres.
- 11500 litres.
- 14375 litres.
Can someone explain this ?
When reheat is used, E.P.R
- is reduced.
- remains constant.
- is increased.
y?? i dont understand
Oil systems consists of
- 2 systems
- 3 systems
- 4 systems
Dose 3 system mean to be 'wet sump','dry sump' & 'full flow', then what about, 'pressure relief valve' & ' total loss system' please give some reference authentic enough to justify your answer. :)
A FADEC system consists of
- H.M.U, A.D.C and sensors.
- E.E.C, A.D.C and sensors.
- H.M.U, sensors and an E.E.C.
is the answer not EEC and ADC as i though the FADEC did not have HMU
The inlet of a turbo fan is
- divergent
- convergent
- convergent-divergent
How come?
Kevlar and Nomex are types of
- glass fibre composite.
- advanced composite.
- aluminium alloy.
Please explain to me the difference between. Glass fibre opposite and a advanced composite ?
Co-axial cables are used
- as they are able to handle high current.
- as the fields due to current flow in the inner and outer cancel each other out.
- as they are protected from electromagnetic interference.
Co-axial cables are used to prevent EM interference and o not cancel each other out. Incorrect answer I believe
A worm drive creates
- a drive in 2 planes and transmits both directions.
- a drive in 1 plane but transmits both directions.
- a drive in 2 planes but transmits 1 direction only.
Can somebody explain to me how a worm drive dives in 2 planes and a single direction? I believe it is 1 plane with 2 directions I.e. forwards nd reverse in the same plane
log 100+2 =
- 4
- log 102
- log 200
Please explain log100+2 is 4
What is log6^3?
- 6log3
- log18
- 3log6
please explai log63 is 3log6
An aircraft flying in "ground effect" will produce
- more lift than a similar aircraft outside of ground effect.
- less lift than a similar aircraft outside of ground effect.
- the same lift as a similar aircraft outside of ground effect.
What is ''ground effect''?
The 5th coloured band on a resistor represents the
- reliability or temperature coefficient.
- tolerance.
- multiplier.
Isn't it the tolerance in coloured band is represent in the 4th band?
Potentiometers are used as a
- variable voltage source.
- variable resistor.
- variable current source.
Isn't it potentiometer relates to variable voltage source?
What happens to the current in a series resistive resonant circuit?
- It is maximum.
- It is minimum.
- It is zero.
Isn't it that at resonant, we have high impedance hence we should have minimum current flow?
With a trailing edge flap being lowered, due to rising gusts, what will happen to the angle of attack?
- Tend to decrease.
- Stay the same.
- Tend to increase.
Someone can show me why the angle of attack tend to increase?
An aircraft flying below the tropopause descends at a constant True Airspeed, its Mach. No. will
- stays constant.
- rise.
- decrease.
why? If TAS is costant the Mach No. will be constant for me. Help?
The process of removing roots from the denominator of fractions is called what?
- Rationalizing the denominator.
- Squaring the denominator.
- Derooting the denominator.
i'm confuse right now because before this the answer was squarizing the denominator. but now the answer is rationalizing the denominator. which one is the correct one?
The arithmetic logic unit (ALU) in a central processor unit (CPU) carries out
- addition, subtraction, multiplication and division.
- data storage, retrieval, and logical comparisons.
- timing, synchronisation, and bus control operations.
aren't multiplication and division result of addition and subtraction?
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.
What is the depth of water in the tank shown if the volume of water is 4000 litres?
- 50 cm
- 80 cm
- 5 m
can someone explain the calculation of this question...i can't get it..thank you so much
If on a flight deck EFIS system all the displays were missing one bit of information. This is most likely to be
- the input sensor bus and display controller.
- the input sensor bus and display processor.
- the display controller and symbol generator.
why should the symbol generator be faulty since each dislay is driven by a different one?
(unless of course when all other symbol generators have failed)
A sector with angle A is subtended to the centre point of a circle. Area of the sector is proportional to
- angle A.
- cos A.
- sin A.
Explain
