From that list, only the frequency makes the difference.
Einstein won his only Nobel Prize for his explanation of this effect.
Answer:
work done would be I don't know
Answer:
44.1 m
Explanation:
<u>Given:</u>
= speed of sound in air = 343 m/s
= speed of sound in the rod = 
= times interval between the hearing the sound twice = 0.12 s
<u>Assumptions:</u>
= length of the rod
= time taken by the sound to travel through the rod 
= time taken by the sound to travel to through air to the same point = 
We know that the distance traveled by the sound in a particular medium is equal to the product of the speed of sound in that medium and the time taken.
For traveling sound through the rod, we have
..........eqn(1)
For traveling sound through the air to the women ear for traveling the same distance, we have
Hence, the length of the rod is 44.1 m.
<span>Chromium
is represented by the element Cr with an atomic number of 24 and a molar mass
of 52 gram per mole. The number of protons in the Chromium atom is the atomic
number, so it has 24 protons. And the protons of chromium atom is equal to the
number of electrons, so 24 electrons.</span>
