If a sound with frequency fs is produced by a source traveling along a line with speed vs. If an observer is traveling with spee
Alexus [3.1K]

Answer:

457.81 Hz

Explanation:

From the question, it is stated that it is a question under Doppler effect.

As a result, we use this form

fo = (c + vo) / (c - vs) × fs

fo = observed frequency by observer =?

c = speed of sound = 332 m/s

vo = velocity of observer relative to source = 45 m/s

vs = velocity of source relative to observer = - 46 m/s ( it is taking a negative sign because the velocity of the source is in opposite direction to the observer).

fs = frequency of sound wave by source = 459 Hz

By substituting the the values to the equation, we have

fo = (332 + 45) / (332 - (-46)) × 459

fo = (377/ 332 + 46) × 459

fo = (377/ 378) × 459

fo = 0.9974 × 459

fo = 457.81 Hz

After measuring a sample of individuals, a researcher finds that one participant's score is three times bigger than another part
Strike441 [17]

Answer:

<u>Ratio</u> scale.

Explanation:

  • Ratio scale is a quantitative scale used for variable measurement which allows any researcher to compare the intervals of the measured parameter.
  • Ratio scale is the 4th level of measurement having a zero point or character of origin.
  • Ratio scale possesses most of the features of the other three variable measurement scale i.e ordinal, nominal and interval scales.
  • Nominal variables are used to name, or label a series of values.
  • Ordinal scales provide a sufficient amount of information about the order of choices, such as one would be able to understand from using a customer satisfaction survey, while the interval scales give us the order of values and also about the ability to quantify the difference between each one.
