Answer:

2\ \text{minutes}

Explanation:

d = Distance traveled = 40.8 km

s = Speed of jet = 340 m/s

Time is given by

t=\dfrac{d}{s}

\Rightarrow t=\dfrac{40.8\times 10^3}{340}

\Rightarrow t=120\ \text{s}

\Rightarrow t=\dfrac{120}{60}=2\ \text{minutes}

The time taken to complete the journey is 2\ \text{minutes}.

Ten students stand in a circle and are told to make a transverse wave. What best describes the motion of the students? Each stud
Bond [772]

Lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students. Option D is correct.

<h3>What is a Transverse wave?</h3>
  • The wave in which the oscillation of particles is is perpendicular to the direction of energy transfer.

  • The students can make a transverse wave by raising their hands up and then down, one student at a time.

  • The raised hand represents the oscillation of particles while the sequence of the raising hand represents the direction of energy transfer.

Therefore, lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students.
