Light travels in electromagnetic waves in the form of photons. What do photons travel in? Can a frequency have weight? Carry weight? According to Einstien a photon with energy proportional to its frequency basically explains ultraviolet light(among other things), so does that mean light travels within a "larger" version of itself?
We know that light doesn't need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.
Light contrasts with sound, which travels through the air (or some other material medium). If you're stationary with respect to the air, then the speed of sound is the same in all directions. But if you're moving with respect to the air, the speed of sound will be the same in all directions relative to the air---which means that sound coming up in front of you will seem faster and sound catching up to you from behind will seem slower.
If light were a disturbance in a medium, it would exhibit the same behaviour. But light never does---its speed is the same under all circumstances. So it does you no good to postulate an aether. You can still do it, but it makes the theory more complicated than necessary. The only reason to postulate an aether is that you're uncomfortable with the idea of waves not needing a medium. But our modern understanding of quantum mechanics is that all kinds of particles have a wavelike nature, so, if you accept that matter can travel through empty space, you should have no problem accepting the same for light.
so it's true
Answer: Decreased risk of heart attack
Explanation:
thats the answer because it actually
increase rish of heart attack
Hope this helps :)
A is the answer to what your asking
Ok so I think you would first subtract
156 - 50 = 106
Since atomic number is based on the number of protons, you should subtract the 50 from 156
106 should be your answer
Hope this helps!
The area of the sprinkles can be determined through the area of a circle that is pi * r^2 in which the given dimensions above are the radii, r. The second scenarios radius is only half of the original, that is 4 ft. In this case, we can compute the area of the second again. We calculate next the difference of two areas of circles.
