Is this feeling something you would like to talk about?
Answer:
The correct answer is - Changing PRF.
Explanation:
Pulsed wave Doppler uses the principle of Doppler effect that objects that move changes the characteristic of sound waves. It is creates images by sending the short and quick pulses of the sound, it helps in the determining the velocity of blood in a exact time and location.
PRF or pulse repetition frequencies, is a Doppler sampling frequency that can affect the acoustic exposure of the scanning. PRF is measured in KHz.
Thus, the correct answer is - changing PRF.
Answer: They main causes are 1. Sewage, 2. Oil Polution 3.Radioactive waste.
Explanation: ---
Assuming the given data is normally distributed and 99.7% of the parts were accepted, the limits will be; <u><em>Between 3.085 m and 3.115 m</em></u>
We are given;
Sample mean; x' = 3.1 m
Standard deviation; σ = 0.005 m
Percentage of parts accepted = 99.7%
According to the Empirical Rule, it states that 99.7% of data observed following a normal distribution will lie within 3 standard deviations of the mean.
Thus, the limits will be;
Interval = x' ± 3σ
Interval limit = 3.1 ± (3 × 0.005)
Interval limit = 3.1 ± 0.015
Interval limit = (3.1 - 0.015), (3 + 0.015)
Interval limit = (3.085, 3.115)
