A type O star is likely to appear blue.
Answer:
Sample Response: In a vacuum, there are no atoms or particles that interfere with the path of light. However, in other media, the speed of light is lower than 3.0 × 108 m/s because the wave is continuously absorbed and re-emitted by each atom in its path. The differences in speed are due to the composition of the medium and the density of the particles in the medium.
Explanation:
Answer:
0.1143m
Explanation:
W=f×s
8=70s
make s the subject of the formula
s=8/70
=0.1143m
That depends on what you want to use them for.
As sources of light, they are somewhere around 15% - 20% efficient.
As heaters, they are somewhere around 80% - 85% efficient.
They are the physics of the world??
