What is the type of motion when a body repeats its motion in the same time interval?

  1. Periodic motion

  2. Random motion

  3. Oscillatory motion

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Periodic motion - The bodies occupy a particular position at regular intervals, e.g. position of minute hand in a clock once in every 60 minutes, hour hand in a clock once in every 12 hours, position of planets in their orbits around the sun.

Directions: Pick the odd one out.

  1. Repulse

  2. Ensnare

  3. Captivate

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Repulse is the odd one out because it means to drive away or cause aversion, while ensnare, captivate, and mesmerize all mean to attract, capture attention, or hold fascination. Repulse is the opposite in meaning - it pushes away rather than drawing in.

Multiple choice

Which of the following erroneous readings is an attitude indicator that may indicate while deaccelarating?

  1. Pitch up attitude

  2. Pitch down attitude

  3. Turn towards right

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When an aircraft decelerates rapidly, the attitude indicator's gyro exhibits precession error, temporarily showing a false pitch-down indication. This occurs because the gyro mechanism responds to acceleration forces. The pilot must recognize this as an instrument error and cross-check with other instruments like the VSI and altimeter to maintain proper attitude.

Multiple choice

  2. Thermotropism

  3. Electrotropism

  4. Thigmotropism
Reveal answer Fill a bubble to check yourself
