By the end of the Paleozoic era, the continents started to split up into
the places that we know them today. At the end of the Paleozoic era,
there was mass extinction on Pangaea, and it took almost 30 million
years for the Earth to recover. When the mass-exitinction occurred, the
Earth was in the Permian-Triassic period of the Paleozoic Era.
13.5 g ---> 1 cm3
50.0 g ---> ?? cm3
?? = (50.0 * 1 ) / 13.5 = 3.704 cm3
The mercury would occupy 3.704 cm3
I think the answer would be that mirrors reflect and lenses transmit. i hope this was helpful!
Answer:
0.57 m
Explanation:
The wavelength of a wave is given by:
where
is the wavelength
v is the speed of the wave
f is its frequency
In this problem, we have
v = 343 m/s is the speed of a sound wave through air
is the frequency of the wave
Substituting into the formula, we find the wavelength
