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.
Answer:
a) HNO3
b) 26.8g (3 s.f.)
c) 1.29g (3 s.f.)
Please see the attached pictures for full solution.
To balance an equation, ensure that the number of atoms for each element is the same on both sides.
