Earth's atmosphere is a <em>mixture</em> of gases that have
not reacted to become chemical compounds.
Answer:
49.6°
Explanation:
= Unpolarized light
= Light after passing though second filter = 
Polarized light passing through first filter
Polarized light passing through second filter
The angle between the two filters is 49.6°
If one reverse the orientation of a permanent magnet ITS MAGNETIZATION WILL BE PERMANENTLY REVERSED. This is because, the magnetic domains inside the permanent magnet aligned with the new applied field and increase with it while those domains that are anti aligned with that field will shrink.
Work is defined to be force multiplied by distance. If one component of the equation is decreased while aiming to keep the resulting value, then the other component must be increased. In that sense, to keep the same amount of work while reducing the force, the distance where the force is exerted should be increased.
