Effectus [21]

Ah hah !  That description fits things like mass, linear momentum,
energy, angular momentum, electric charge, and politicians.  They
never appear or disappear, they just move from place to place. 
We say that those quantities are conserved.

An echocardiogram uses 4.4 MHz ultrasound to measure blood flow in the aorta. The blood is moving away from the probe at 1.4 m/s
Alinara [238K]

Answer:

\Delta f=17959.2\ Hz

Explanation:

Given:

  • original frequency of  the wave, f=4.4\times 10^6\ Hz
  • velocity of the blood stream moving away, v=1.4\ m.s^{-1}

<u>Doppler shift is given as:</u>

\frac{f}{f_o} =\frac{s+v_s}{s-v_o}

where:

s = velocity of ultrasound in blood = 1570\ m.s^{-1}

v_s= velocity of sound  source towards the observer

v_o= velocity of the observer away from the source

\frac{4.4\times 10^6}{f_o} =\frac{1570+0}{1570-1.4}

f_o=4396076.43\ Hz

Therefore the shift in frequency:

\Delta f=f-f_o

\Delta f=3923.56\ Hz

Summarize the step you might use to Carry out an investigation using scientific method
Aleksandr [31]

The summary of the step you might use to carry out an investigation using scientific method include:

  • Observation
  • Hypothesis
  • Experiment
  • Conclusion

<h3>What is Scientific method?</h3>

This is defined as a systematic approach which helps to predict how several elements in the universe works.

This usually starts with observing a phenomenon and making a hypothesis. This is usually followed by conducting experiment to ascertain its authenticity before a conclusion is drawn.

An object that’s charged has more electrons than protons. An object that’s charged has fewer electrons than protons. An object t
Levart [38]
An element is neutral when the charged is equal to zero. This means that the number of electrons and protons are equal. When an object has a NEGATIVE charge, its electrons are more than its protons. Also, the object has a POSITIVE charge when the number of its electrons are fewer compared to the number of the protons.
