15. List and define the characteristics of a wave. You should have 4 complete content related sentences (one for each part of th
forsale [732]

The characteristics of wave are amplitude, speed , frequency and wavelength.

<u>Explanation:</u>

Amplitude is defined as the distance covered by the particles or molecules moving in a wave nature. So the maximum positive and negative peak position is termed as amplitude of the wave.

Every wave forms a series of crests and trough regions. The crest region is the positive amplitude while the trough region is the negative amplitude. The distance between two successive crests and troughs are termed as wavelength.

A single crest and trough forms a complete cycle. So the number of times a cycle is repeated for a given time is known as frequency. Speed is defined as the product of frequency and wavelength of the wave. In other words, speed of a wave is the rate at which the particles are moving a given area per unit time.

Answer:

A.   it is the lowest at low temperatures

Explanation:

It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.

The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.

  • Kinetic energy is directly proportional to the temperature of a substance.
  • The higher the temperature, the more the kinetic energy of the molecules within a system.
  • At low temperature, kinetic energy is the lowest.
  • At the highest temperature, kinetic energy is the highest
