What color is a black light bulb?
- A.
Yellow
- B.
Green
- C.
Purple
- D.
Blue
Correct Answer
C. PurpleExplanation
A black light bulb emits ultraviolet light, which is not visible to the human eye. However, certain materials, such as fluorescent substances, can absorb this ultraviolet light and re-emit it as visible light. This visible light appears to be purple in color when viewed with the naked eye. Therefore, the color of a black light bulb is purple.Rate this question:

When the moon appears to block the sun, as seen from Earth, what is the event called?
- A.
Lunar Eclipse
- B.
Blue Moon
- C.
Solar Eclipse
- D.
Solar Flare
Correct Answer
C. Solar EclipseExplanation
A solar eclipse occurs when the moon passes between the sun and Earth, blocking the sun's light and casting a shadow on Earth's surface. This alignment causes the moon to appear to completely or partially cover the sun, resulting in a temporary darkening of the sky. During a solar eclipse, the moon's shadow can be seen on Earth, creating a visually stunning phenomenon. Therefore, the correct answer is Solar Eclipse.Rate this question:

What is a nuclear reaction in which two small atomic nuclei fuse called in scientific terms?
- A.
Nuclear Fusion
- B.
Fission
- C.
Gravity
- D.
Nebula
Correct Answer
A. Nuclear FusionExplanation
Nuclear fusion is a scientific term used to describe a nuclear reaction in which two small atomic nuclei merge together to form a larger nucleus. This reaction releases a tremendous amount of energy and is the process that powers the sun and other stars. Unlike nuclear fission, which involves the splitting of a large atomic nucleus into smaller parts, nuclear fusion involves the combination of smaller nuclei to form a larger one. Gravity and nebula are not scientific terms used to describe this specific type of nuclear reaction.Rate this question:

What do we call data sent from a spacecraft to ground stations?
- A.
Telemetry
- B.
Element
- C.
Signal Path
- D.
Frequency Response
Correct Answer
A. TelemetryExplanation
Telemetry refers to the data sent from a spacecraft to ground stations. It includes various parameters such as temperature, pressure, and velocity, which are collected by sensors on the spacecraft and transmitted back to Earth for analysis and monitoring. This data is crucial for monitoring the health and performance of the spacecraft, as well as for conducting scientific research and making informed decisions during space missions.Rate this question:

What is a unit that measures force?
- A.
Newton
- B.
Kelvin
- C.
Gauss
- D.
Watt-Hour
Correct Answer
A. NewtonExplanation
A Newton is the unit used to measure force. It is named after Sir Isaac Newton, who made significant contributions to the field of physics. The Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. This unit is commonly used in various scientific and engineering applications to quantify the amount of force exerted on an object.Rate this question:

- A.
Ohm
- B.
Current
- C.
Epa
- D.
Glaucoma
Correct Answer
A. OhmExplanation
The measure of electrical resistance is commonly known as Ohm. Ohm is a unit used to quantify the resistance of an electrical circuit. It is named after Georg Simon Ohm, a German physicist who formulated Ohm's law, which relates current, voltage, and resistance in a circuit.Rate this question:

What is a character encoding scheme used by many computers called?
- A.
Morse Code
- B.
Html
- C.
Ascii
- D.
Wordpad
Correct Answer
C. AsciiExplanation
ASCII (American Standard Code for Information Interchange) is a character encoding scheme used by many computers. It represents characters as numerical codes, allowing computers to understand and display text. Morse Code is a communication method that uses a series of dots and dashes, not a character encoding scheme. HTML is a markup language used for creating web pages, not a character encoding scheme. Wordpad is a text editor program, not a character encoding scheme.Rate this question:

Which one of the food groups is a good source of calcium, protein, riboflavin and vitamin A?
- A.
Milk Group
- B.
Fruit Group
- C.
Vegetable Group
- D.
Grain Group
Correct Answer
A. Milk GroupExplanation
