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:
+2
Explanation:
+2 is the calcium carbonate oxidation number
K, ca, sc is the right answer. Take a look at table S of your chemistry reference table.
The final temperature (°C) of the air at this elevation is 326.3K.
<h3>How to calculate temperature?</h3>
The temperature of a gas can be calculated using the combined gas law equation as follows:
P₁V₁/T₁ = P₂V₂/T₂
Where;
- P₁ = initial pressure
- V₁ = initial volume
- T₁ = initial temperature
- P₂ = final pressure
- V₂ = final volume
- T₂ = final temperature
According to this question, 1.20L weather balloon on the ground has a temperature of 25.0°C and is at atmospheric pressure (1.00 atm). When it rises to an elevation where the pressure is 0.730 atm, then the new volume is 1.80L. The final temperature can be calculated thus:
1 × 1.2/298 = 0.730 × 1.8/T₂
0.004027T = 1.314
T = 326.3K
Therefore, 326.3K is the final temperature of the balloon.
