Which of the following phenomena cannot be observed on the surface of the Moon?
- A.
Rising and Setting of the Sun
- B.
Solar Eclipse
- C.
Motion of Comets
- D.
Twinkling of Stars
Correct Answer
D. Twinkling of StarsExplanation
The twinkling of stars cannot be observed on the surface of the Moon because it lacks an atmosphere. Twinkling occurs when the light from stars passes through Earth's atmosphere and gets refracted or bent due to the varying density of air. Since the Moon has no atmosphere, there is no medium for the starlight to pass through and hence no twinkling can be observed.Rate this question:

What CREATES more drag on an airplane?
- A.
Streamline Shaped Body
- B.
Jet Engine
- C.
Extra Weight
- D.
Things sticking out of the plane's body
Correct Answer
D. Things sticking out of the plane's bodyExplanation
Things sticking out of the plane's body create more drag on an airplane. Drag is the force that opposes the motion of an aircraft through the air. When objects protrude from the streamlined body of the plane, they disrupt the smooth airflow, causing turbulence and increasing the drag. This can include antennas, landing gear, wingtip devices, and other external components. Streamline shaped body, jet engine, and extra weight do not directly contribute to creating more drag on an airplane.Rate this question:

Which one of the following doesn't fly?
- A.
Bee
- B.
Airplane
- C.
Penguin
- D.
Frisbee
Correct Answer
C. PenguinExplanation
Penguins do not fly because they are flightless birds. Unlike bees, which have wings and can fly, penguins have adapted to life in the water and use their wings for swimming instead. Similarly, airplanes are man-made machines designed for flying, and frisbees can be thrown through the air. However, penguins are well-suited for swimming and diving rather than flying.Rate this question:

- A.
It would crash
- B.
It would go slower
- C.
It would go faster
- D.
It would stay suspended in mid air
Correct Answer
C. It would go fasterExplanation
If the thrust of the plane becomes greater than the drag, it means that the force pushing the plane forward is stronger than the force resisting its motion. As a result, the plane would accelerate and go faster.Rate this question:
-

How do airplanes get their thrust for extended periods of time?
- A.
Jet fuel
- B.
Propeller
- C.
All of these together.
- D.
Jet Engine
Correct Answer
C. All of these together.Explanation
Airplanes get their thrust for extended periods of time from a combination of jet fuel, propellers, and jet engines working in tandem. Jet fuel is used as a source of energy to power the engines, while propellers help generate thrust by pushing air backwards. Jet engines, on the other hand, work by compressing incoming air and mixing it with fuel before igniting it, creating a high-speed jet of exhaust gases that propel the aircraft forward. Therefore, all of these components work together to provide the necessary thrust for airplanes to fly for extended periods.Rate this question:

The tilt of Earth's axis has no effect on the length of the day.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The tilt of Earth's axis does have an effect on the length of the day. This is because the tilt causes the angle at which sunlight hits different parts of the Earth to change throughout the year. During the summer solstice, when the axis is tilted towards the sun, the days are longer. Conversely, during the winter solstice, when the axis is tilted away from the sun, the days are shorter. Therefore, the tilt of Earth's axis does impact the length of the day.Rate this question:
