Which device holds a phono cartridge?
- A.
Cardioid
- B.
Armature
- C.
Tone Arm
- D.
Plate
Correct Answer
C. Tone ArmExplanation
The correct answer is Tone Arm. A phono cartridge is a small device that contains a stylus or needle, which is used to read the grooves on a vinyl record. The tone arm is the part of a turntable that holds the phono cartridge and allows it to move across the record surface. It is responsible for accurately tracking the grooves and transferring the vibrations to the cartridge, which then converts them into an electrical signal that can be amplified and played through speakers.Rate this question:

A picture condition in which horizontal lines are displaced in an irregular manner, fits which audio/video term?
- A.
Tearing
- B.
Vidicon
- C.
Wrms
- D.
IR
Correct Answer
A. TearingExplanation

A weight or force pushing the stylus down into the record groove, fits which audio/video term?
- A.
F-Stop
- B.
Tracking Force
- C.
Dynamic Range
- D.

How long did it take to design and build the world's first privately funded spacecraft, "Spaceship One"?
- A.
Sixteen Months
- B.
Three Years
- C.
Twenty Years
- D.
Sixteen Years

What are programs designed to allow 3rd parties unauthorized access to the computer systems they infect called?
- A.
Adware
- B.
Trojans
- C.
Spam
- D.
Cgi Programs
Correct Answer
B. TrojansExplanation
Trojans are programs designed to allow unauthorized access to computer systems. Unlike viruses or worms, they do not replicate themselves but instead masquerade as legitimate software to deceive users into installing them. Once installed, Trojans can give remote access to hackers, enabling them to steal sensitive information, control the infected system, or launch further attacks. Adware, spam, and CGI programs do not necessarily involve unauthorized access to computer systems, making them incorrect choices for this question.Rate this question:

What is the fasting growing plant?
- A.
Dandelion
- B.
Sunflower
- C.
Moss
- D.
Bamboo
Correct Answer
D. BambooExplanation
Bamboo is the correct answer because it is known to be the fastest-growing plant in the world. Some species of bamboo can grow up to 91 cm (35 inches) per day, making it an incredibly rapid-growing plant. Its unique growth rate is due to its specialized structure and ability to quickly absorb and transport water and nutrients. Bamboo's fast growth makes it a highly sustainable and renewable resource, which is why it is widely used for various purposes such as construction, furniture, and even food.Rate this question:

One nautical mile equals one minute of what?
- A.
Latitude
- B.
Miles
- C.
Time
- D.
Distance
Correct Answer
A. LatitudeExplanation
One nautical mile equals one minute of latitude. This means that for every minute of latitude traveled, a ship or aircraft will cover a distance of one nautical mile. Latitude is a measurement of distance north or south of the equator, and nautical miles are used in navigation to calculate distances on the Earth's surface. Therefore, the correct answer is latitude.Rate this question:

If you yelled for 8 years, 7 months and 6 days, you would have produced enough sound energy radiation to do what?
- A.
Heat One Cup Of Coffee
- B.
Bust An Ear Drum
- C.
Start A Fire
- D.
Create A Sonic Boom
Correct Answer
A. Heat One Cup Of CoffeeExplanation
If you yelled for 8 years, 7 months, and 6 days, you would have produced a significant amount of sound energy radiation. This energy can be converted into heat energy, and it is estimated that it would be enough to heat one cup of coffee. Sound energy is a form of kinetic energy, and when it is absorbed by an object, it causes the molecules to vibrate, resulting in an increase in temperature. Therefore, the correct answer is "Heat One Cup Of Coffee."Rate this question:

It is about 3300 miles from Seattle to Miami, how fast do you need to fly to get there in 3 hours?
- A.
1000 Mph
- B.
110 Mph
- C.
700 Mph
- D.
1100 Mph
Correct Answer
D. 1100 MpHExplanation
To determine how fast you need to fly to cover a distance of 3300 miles in 3 hours, you can divide the distance by the time. Therefore, 3300 miles divided by 3 hours equals 1100 miles per hour (Mph). This means that you would need to fly at a speed of 1100 Mph to reach Miami from Seattle in 3 hours.Rate this question:

Which one of the following disorders is sex-linked?
- A.
PKU
- B.
Fever
- C.
Color Blindness
- D.
Cystic Fibrosis
Correct Answer
C. Color BlindnessExplanation
Color blindness is a sex-linked disorder because it is caused by a gene located on the X chromosome. Since males have only one X chromosome, they are more likely to inherit the disorder if their mother carries the gene. Females, on the other hand, have two X chromosomes, so they have a lower chance of inheriting the disorder. This pattern of inheritance makes color blindness more common in males than in females.Rate this question:

What are you hearing when you put a seashell to your ear?
- A.
Blood Pulsating
- B.
Shell Vibrations
- C.
Ear Feedback
- D.
Air Resonating
Correct Answer
D. Air ResonatingExplanation
When you put a seashell to your ear, you are hearing the sound of air resonating. The shape of the seashell acts as a natural amplifier, capturing and amplifying the surrounding sounds. As you hold the seashell to your ear, the air inside the shell vibrates in response to the sound waves in the environment, creating a resonating effect. This amplified sound is what you perceive as the sound of the ocean or a rushing noise.Rate this question:

What color eyes are the most sensitive to light?
- A.
Green
- B.
White
- C.
Blue
- D.
Brown
Correct Answer
C. BlueExplanation
Blue eyes are the most sensitive to light because they have less melanin, which is a pigment that helps protect the eyes from the harmful effects of sunlight. The lack of melanin in blue eyes allows more light to enter the eyes, making them more sensitive to bright lights and sunlight. This can cause discomfort and potentially lead to vision problems.Rate this question:
