It depends on how you use it! Sometimes it changes to heat and sometimes friction use it
Answer: (B) They can be penetrated only with longer wavelengths such as radio and infrared.
Explanation:
A dark nebula is a type of interstellar cloud with such a high density that it "hides" the light of the background stars.
It should be noted that these nebulae are composed mostly of hydrogen (the star's primary fuel), and the absence of light (in the visible range of the electromagnetic spectrum) is caused by the interstellar solid dust that constitutes the cloud, which is why they are also called absorption nebulae.
However, <u>if powerful telescopes that detect at long wavelengths, such as infrared and X-rays, it is possible to observe through these nebulae and even observe the existence of young stars.</u>
Explanation:
The phenomenon of superimposing of two waves such that the resultant wave have greater, lower, or the same amplitude.
There are two conditions for the interference.
- Constructive wave interference: This type of interference occurs after adding of two maxima such that the amplitude of the resulting wave is equal to the sum of the amplitudes of individual waves.
- Destructive wave interference: In this type of interference, the amplitude of the resulting wave gets reduced as the crest of one wave meets with the trough of another wave.

This shows that a difference group of chemicals will activate different location on the olfactory bulb. The same pattern always occurs during large chain length that shows it's located also to the left</span>
If it's traveling at 1 m/s, it takes five seconds to travel five meters.
