Photonic molecules are a theoretical natural form of matter which can also be made artificially in which photons bind together to form "molecules". Photonic molecules are formed when individual (massless) photons "interact with each other so strongly that they act as though they have mass".
Answer:
The answer is 850ft.
Step-by-step explanation:
If it was originally at 800ft, and it ascended 250, then you would subtract 250 from 800 leaving you at now 550ft. then you descended 300ft, then you would add 300 to 550, currently leaving you at 850ft.

Answer:
![x^2+18=-9x : x = -3, x = -6](https://tex.z-dn.net/?f=x%5E2%2B18%3D-9x%20%3A%20x%20%3D%20-3%2C%20x%20%3D%20-6)
Step-by-step explanation:
![x^2+18=-9x](https://tex.z-dn.net/?f=x%5E2%2B18%3D-9x)
Add 9x to both sides:
![x^2+18+9x=-9x+9x](https://tex.z-dn.net/?f=x%5E2%2B18%2B9x%3D-9x%2B9x)
Simplify:
![x^2+9x+18=0](https://tex.z-dn.net/?f=x%5E2%2B9x%2B18%3D0)
Solve with the quadratic formula:
For a quadratic equation of the form
the solutions are:
![x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x_%7B1%2C%5C%3A2%7D%3D%5Cfrac%7B-b%5Cpm%20%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
For ![a=1,\:b=9,\:c=18:\quad x_{1,\:2}=\frac{-9\pm \sqrt{9^2-4\cdot \:1\cdot \:18}}{2\cdot \:1}](https://tex.z-dn.net/?f=a%3D1%2C%5C%3Ab%3D9%2C%5C%3Ac%3D18%3A%5Cquad%20x_%7B1%2C%5C%3A2%7D%3D%5Cfrac%7B-9%5Cpm%20%5Csqrt%7B9%5E2-4%5Ccdot%20%5C%3A1%5Ccdot%20%5C%3A18%7D%7D%7B2%5Ccdot%20%5C%3A1%7D)
![x =\frac{-9 + \sqrt{9^2-4\cdot \:1\cdot \:18}}{2\cdot \:1} : -3](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B-9%20%2B%20%5Csqrt%7B9%5E2-4%5Ccdot%20%5C%3A1%5Ccdot%20%5C%3A18%7D%7D%7B2%5Ccdot%20%5C%3A1%7D%20%3A%20-3)
![x =\frac{-9 - \sqrt{9^2-4\cdot \:1\cdot \:18}}{2\cdot \:1} : -6](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B-9%20-%20%5Csqrt%7B9%5E2-4%5Ccdot%20%5C%3A1%5Ccdot%20%5C%3A18%7D%7D%7B2%5Ccdot%20%5C%3A1%7D%20%3A%20-6)
The solution to the quadratic equation are:
![x=-3,\:x=-6](https://tex.z-dn.net/?f=x%3D-3%2C%5C%3Ax%3D-6)
Hope I helped. If so, may I get brainliest and a thanks?
Thank you, have a good day!

uhh as each scientific notation is 10 more, so therefore 5 x 10
