A mass of 20kg produces a momentum of 300kgm/s. What is the Kinetic energy?
- 3250 Joules.
- 2250 Joules.
- 4500 Joules.
How is this solution calculated?
Which of the following is true?
- Noise always affects the standard of work for every person.
- Noise has absolutely no measurable impact on a person's work.
- Noise does affect the standard of work with certain people.
Noise affects the standard of work proportionately with the level of the noise.
Fibre optic cables are capable of transmitting light at
- 1.99 * 108 m/s.
- 3.00 * 108 m/s.
- 0.99 * 108 m/s.
Could someone tell me where to find info about this
Kerosene will burn effectively at an air/fuel ratio of
- 150:1.
- 15:1.
- 45:1.
but the mixture provided to the combustion chamber is of ratio 45:1
As a block of ice is melted (to 4 degrees C). Its volume
- stays same.
- decreases.
- increases.
whay?
What is the area of the shape shown, in square centimeters?
- 1000
- 1130
- 1264
How it is?
On an electrical deicing system fast cycle is used
- at low air temperature.
- at high air temperature.
- on the ground.
fast cycle means more deicing so if the temp of the air high, it requires less deicing so switching cycle should be less.
6^7 divided by 12^7 is equal to
- 1/128.
- 1/20.
- 1/2.
how its posible?
The area of a circle whose circumference is given as 12cm is approximately
- 3.8 cm^2.
- 11.3 cm^2.
- 38 cm^2.
how to solve? I get 36cm2
In a turn the up-going wing causes a
- de-stabilizing effect due to increased AoA.
- de-stabilizing effect due to decreased AoA.
- stabilizing effect due to decreased AoA.
Why the aoa decrease?
When resetting the CSD on the ground, the engine should be
- rotating at idle.
- stationary.
- rotating at Nsync.
but while connecting IDG the N2 should be rotating.
The CSD or IDG speed governor setting
- is not allowed to be adjusted.
- is adjusted with the engine stationary.
- is adjusted with the engine running.
b737 AMM:
E. Adjust the CSD Output Speed
SUBTASK 24-11-11-215-039-001
WARNING: MAKE SURE THE ENGINES ARE STOPPED WHEN YOU ADJUST THE CSD. THE
CSD ADJUSTMENT PUTS MAINTENANCE PERSONS IN THE DANGEROUS ZONE
THAT IS AROUND THE ENGINE INLET. ENGINE SUCTION CAN CAUSE INJURY TO
PERSONS.
(1) Make sure that the engine is stopped (PAGEBLOCK 71-00-00/201)...............
If the TAS of an aircraft increases, the CSU will
- increase the blade angle to provide constant RPM.
- decrease the blade angle to provide constant RPM.
- change the blade angle to provide constant RPM.
Why?
Which of the graphs shown is given by the equation y = x^2 + 3?
- a
- b
- c
can someone explain this to me
The minimum propeller pitch is established by the
- superfine pitch stop.
- pitch lock.
- flight fine pitch stop.
Why?
Alert Height is when
- a decision of whether to land is made
- an alert of the altitude of the aircraft is made
- an alert of the ground proximity is made
There are two same questions and two different answers. In this case the correct answer is an alert of the altitude of the aircraft is made. Other case correct answer is a decision of whether to land is made.
So what is the right answer then?
In a bank, the weight is
- increased.
- decreased.
- unchanged.
Why?
Glass is an example of a
- paramagnetic material.
- coercive material.
- diamagnetic material.
In another questions glass is said to be paramagnetic. What's the correct one?!
Thanks
What is the normal spacing between rivets?
- 2 D.
- 3 D.
- 4 D.
wasn't it from 3 to 10 times the diameter?
What happens to load factor as you decrease turn radius?
- It increases.
- It decreases.
- It stays constant.
Why?
Electrostatic discharge occurs when
- materials of similar composition are physically separated from one another.
- materials of the same potential are placed into direct contact with each other.
- materials of different potential are brought in close proximity to each other.
I think this one is wrong
A semiconductor which emits photons and releases electrons when stimulated by photons is called
- a power diode.
- a laser diode.
- a zener diode.
Isn't the answer LED?
An aircraft may have been HIRF affected.
- A bonding load check is required.
- A static wick check is required.
- A full wiring loom check needed.
Explain
In order to maintain HIRF protection, bonding checks between airframe and electrical components carrying voltages greater than 50 volts RMS or DC or main earth return should not exceed
- 5 ohm.
- 1 ohm.
- 3 ohm.
Pls explain.
An aircraft Radio License has to be renewed
- every three years.
- every five years.
- only on change of aircraft ownership.
Aircraft Licences have a 3 year term.
