Answer:
Wavelength
Explanation:
Electromagnetic Waves have different wavelengths.
They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.
The answer is C. Flammability because if you were to test flammability of an object, you would e making a chemical change to the object.
Answer:


is the photon energy of an x-ray
Explanation:
Given:
Energy of photon, 
Then according to given:


is the wavelength
Again,
Energy of photon, 
wavelength of the light, 


<u>Now, photon energy for an x-ray:</u>
wavelength, 

is the photon energy of an x-ray
Answer:
Explanation:
Unknown fork frequency is either
335 + 5.3 = 340.3 Hz
or
335 - 5.3 = 329.7 Hz
After we modify the known fork, the unknown fork frequency equation becomes either
(335 - x) + 8 = 340.3
(335 - x) = 332.3
x = 2.7 Hz
or
(335 - x) + 8 = 329.7
(335 - x) = 321.7
x = 13.3 Hz
IF the unknown fork frequency was 340.3 Hz,
THEN the 335 Hz fork was detuned to 335 - 2.7 = 332.3 Hz
IF the unknown fork frequency was 329.7 Hz,
THEN the 335 Hz fork was detuned to 335 - 13.3 = 321.7 Hz
