What is the voltage of a D cell battery?
- A.
1.0 Volts
- B.
3.5 Volts
- C.
8.0 Volts
- D.
1.5 Volts
Correct Answer
D. 1.5 VoltsExplanation
A D cell battery typically has a voltage of 1.5 volts. This is a common voltage for many types of batteries, including alkaline batteries. The voltage of a battery is a measure of the electric potential difference between the positive and negative terminals of the battery. In the case of a D cell battery, the voltage is 1.5 volts, which means that there is a potential difference of 1.5 volts between the positive and negative terminals. This voltage is suitable for powering a variety of devices, from small electronics to larger appliances.Rate this question:

What is a term describing a flight, which may be conducted where the pilot cannot see outside the aircraft?
- A.
Auto Mode
- B.
Landwise
- C.
Instrument Flight Rules
- D.
Blind Flight
Correct Answer
C. Instrument Flight RulesExplanation
Instrument Flight Rules (IFR) is the correct answer because it accurately describes a flight conducted when the pilot cannot see outside the aircraft. In IFR, pilots rely solely on the aircraft's instruments and navigation systems to navigate and maintain control of the aircraft. This is typically done in adverse weather conditions or at night when visibility is poor. The use of IFR ensures safe and controlled flight operations even when visual references are limited or unavailable.Rate this question:

Which aeronautical term is a regulatory term describing flights where the pilot can see the ground?
- A.
Visual Flight Rules
- B.
Seeing Ground Rules
- C.
All Clear
- D.
Sway
Correct Answer
A. Visual Flight RulesExplanation
Visual Flight Rules (VFR) is a regulatory term used in aeronautics to describe flights where the pilot has visual contact with the ground and can navigate visually. This means that the pilot relies on their own visual observations to navigate and maintain separation from other aircraft. VFR flights are typically conducted during good weather conditions and require the pilot to have a certain level of visibility and cloud clearance. This term is used to differentiate from Instrument Flight Rules (IFR), where pilots rely on instruments for navigation and can fly in poor visibility conditions.Rate this question:

One of the first remote controls was called "Flashmatic". How did it work?
- A.
Radio Waves
- B.
Shining A Beam Of Light Onto A Photoelectric Cell
- C.
It Used An IR
- D.
It Was A Wired Remote
Correct Answer
B. Shining A Beam Of Light Onto A Photoelectric CellExplanation
The correct answer is "Shining A Beam Of Light Onto A Photoelectric Cell". The Flashmatic remote control operated by using a beam of light that was emitted from the remote control and directed towards a photoelectric cell on the television set. When the beam of light was interrupted by pressing a button on the remote control, the photoelectric cell detected the change in light and transmitted a signal to the television to perform the desired action. This technology was later replaced by infrared (IR) remote controls.Rate this question:

In 1956, Robert Adler developed Zenith Space Command and a "modern" wireless remote, how did it work?
- A.
Used Ultrasound To Change The Channel And Volume
- B.
Beam Of Light Onto A Photoelectric Cell
- C.
Infrared Light
- D.
Used Radio Signals
Correct Answer
A. Used Ultrasound To Change The Channel And VolumeExplanation
The correct answer is "Used Ultrasound To Change The Channel And Volume." Robert Adler's Zenith Space Command used ultrasound technology to transmit signals from the remote control to the television. When a button was pressed on the remote, it emitted an ultrasonic sound that was picked up by a microphone in the television. The television then responded accordingly by changing the channel or adjusting the volume. This ultrasound technology was innovative at the time and paved the way for future remote control advancements.Rate this question:

A maximum linear excursion of a speaker voice coil remaining within the magnetic flux field, fits which audio/video term?
- A.
F-Stop
- B.
Xmax
- C.
Driver
- D.
Blooming
Correct Answer
B. XmaxExplanation
Xmax is a term used in audio/video to describe the maximum linear excursion of a speaker voice coil that remains within the magnetic flux field. This refers to how far the speaker cone can move back and forth without leaving the area where the magnetic field is effective. It is an important specification as it determines the speaker's ability to produce low-frequency sounds accurately and without distortion.Rate this question:

What is an electronic circuit that aligns unsynchronized video signals before signal processing?
- A.
Xmax
- B.
Cmos
- C.
Dip
- D.
Timebase Corrector
Correct Answer
D. Timebase CorrectorExplanation
A timebase corrector is an electronic circuit that is used to align unsynchronized video signals before they are processed. It corrects timing errors in the video signals, ensuring that they are in sync and can be properly processed. This is particularly useful in situations where video signals from different sources need to be combined or edited together. The timebase corrector helps to eliminate any discrepancies or inconsistencies in the timing of the video signals, resulting in a smoother and more accurate video output.Rate this question:

A non-inductive resistor with same resistance as the cable being used, fits which audio/video term?
- A.
Comb Filter
- B.
Yagi
- C.
Blooming
- D.
Termination
Correct Answer
D. TerminationExplanation
Termination refers to the process of matching the impedance of a cable or transmission line to the impedance of the connected device or load. In this context, a non-inductive resistor with the same resistance as the cable being used can be used as a termination to ensure proper impedance matching. This helps prevent signal reflections and ensures maximum power transfer, resulting in better audio or video quality. Therefore, the correct answer is Termination.Rate this question:

A length of time a switcher holds on a camera before moving on fits which audio/video term?
- A.
Freeze Frame
- B.
Gen-Lock
- C.
Dwell Time
- D.
Azmith
Correct Answer
C. Dwell TimeExplanation
Dwell Time refers to the length of time a switcher holds on a camera before moving on. It is a term commonly used in audio/video production to describe the duration that a camera shot remains on screen before transitioning to another shot. This term is relevant in live broadcasts or video editing, where the switcher controls the timing and sequencing of different camera shots.Rate this question:
