For the first part of your question:
For the second part of your question:
This still needs to be converted to m/h:
It is D. X rays have a shorter wavelength than microwaves.
Unscrambling
1. resting heart rate
2. overload

4. specificity
5. cool-down
6. progression
7. warm-up
8. the last one can only be instance, but there was a typo on the paper.
Because of how it's worded the answer would most likely be number four
Answer:
The intensity of sound (I) = 3.16 x 10⁻⁶ W/m²
Explanation:
We have expression for sound intensity level (SIL),
Here we need to find the intensity of sound (I).
Substituting
L = 67 dB and I₀ = 10⁻¹² W/m² in the equation
The intensity of sound (I) = 3.16 x 10⁻⁶ W/m²
