Answer:
IF the price of chocolate increases, THEN the amount of chocolate people buy decreases
Explanation:
In a scientific investigation, an observation is first made. Based on this observation, a scientific question is then asked. However, a HYPOTHESIS is given next to explain the question asked. A hyothesis is a testable explanation given to solve an observed problem or provide a possible answer to a question.
The hypothesis must be subject to testing via EXPERIMENTATION. A hypothesis usually goes in an IF, THEN format. In this case with the testable question: How does price affect the amount of chocolate people buy?
A hypothesis that can explain this question is: IF the price of chocolate increases, THEN the amount of chocolate people buy decreases.
Answer:
2270 full wavelengths.
Explanation:
The wavelength
of the sound wave (assuming sound speed of
) is

.
Now, assuming the distance to the last row is 1947m, the number
of wavelengths that fit into this distance are


which is 2270 full wavelengths.
Hence, there are 2270 full wavelengths between the stage and the last row of the crowd.
<span>The first response would be "deca," since this is a multiple of 10^1. B, since it's working off the thousands prefix (10^3), would be "kilo." The third, at 10^-6, would be "micro." Next, at 10^-9, would be "nano," and the final, 10^18, would have a prefix of "exa."</span>
