Answer:

Explanation:
Given:
- original frequency of the wave,

- velocity of the blood stream moving away,

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

where:
s = velocity of ultrasound in blood = 
velocity of sound source towards the observer
velocity of the observer away from the source


Therefore the shift in frequency:


B the goose with most mass
this is because momentum=mass x acceleration
so a larger mass will give a larger momentum ( acceleration stays constant)
Answer: At several different levels, scientific awareness will enhance the quality of life, from the routine functioning of our daily lives to global issues. In energy, conservation, agriculture, health, transportation, communication, security, economics, recreation, and discovery, science informs public policy and personal decisions.

If its atomic number is 48, then it has 48 protons in the nucleus
of each atom. Any more mass than that is supplied by the neutrons
that are mixed in there with the protons.
If the mass is 167, and 48 of those are protons, then there are
(167 - 48) = 119 neutrons
in each nucleus.
