  • Each natural frequency that an object or instrument produces has its own characteristic vibrational mode or standing wave pattern.
  • A harmonic is an integer (whole number) multiple of the fundamental frequency.
  • The harmonics generated depend on the note or chord being played, and each frequency will produce different harmonics.
  • The harmonics heard are based on the fundamental frequency being played and produce a lower amplitude (or volume) as they increase from 1st to 8th harmonic.

 

Additional Information

  • When a string is fixed at both ends, two waves travelling in opposite directions simply bounce back and forth between the ends.
  • This will produce even harmonics.
  • When air is blown into the open organ pipe, the air column vibrates in the fundamental mode.
  • Antinodes are formed at the ends and a node is formed in the middle of the pipe.
  • The frequencies of harmonics are in the ratio of 1: 2 : 3...

Correct answer

Answer: (d)D.

0

Why this answer is correct

The correct answer is 0.

 

Key Points

  • Venus (and the planet Mercury) are the only two planets that don't have a single natural moon orbiting them.

Important Points

  • Venus is only a little smaller than the Earth.
  • Venus is the second closest planet to the sun at a distance of about 108 million km (67 million miles) or 0.72 AU.
  • One day on Venus lasts as long as 243 Earth days (the time it takes for Venus to rotate or spin once).

Additional Information

  • Moons are also known as natural satellites that orbit planets and asteroids in our solar system.

Question 1880

SSC CPO 2020• General Knowledge and General Awareness• General Knowledge and General Awareness

Standing in an open ground on a cloudless day, at what time will your shadow be the shortest?

  1. AOption (a)

    15:00

  2. BOption (b)

    07:00

  3. COption (c)

    12:00

  4. DOption (d)

    09:00

View answer & explanation

Correct answer

Answer: (c)C.

12:00

Why this answer is correct

The Correct Answer is 12:00.

 

Key Points

  • From sunrise to sunset, the sun traces an arc across the sky and reaches its highest point in the sky at local noon.
  • As the sun moves through the sky, the shadow cast by an object is constantly changing in length.
  • The shortest shadow occurs when the sun reaches its highest point, at local noon.

 

Additional Information

  • Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky.
  • As the Earth rotates on its axis, the sun hits each location in the morning at an angle.
  • This makes the shadow appear long.
