Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:
where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as
Therefore, this means that the energy of the wave increases by a factor:
Therefore, the energy of the wave increases by a factor 1.21.
Compound 1 = Carbon 1 atom & Hydrogen 1 atom
Compound 2 = Nitrogen 1 atom & Hydrogen 1 atom
Compound 3 = Magnesium 1 atom
Compound 4 = Sodium 1 atom
This should be the answers because the compounds after the example don’t have any numbers
B)hydrogen ...................
Answer: D. Insects
Fossils that are preserved in the Burgess Shale are mostly the remains of soft-bodied organisms.
So the answer is D because insects don’t really have bones like the rest of the other options. They have exoskeletons which protects their organs and gives them support for moving around.
