Answer:
0.625 c
Explanation:
Relative speed of a body may be defined as the speed of one body with respect to some other or the speed of one body in comparison to the speed of second body.
In the context,
The relative speed of body 2 with respect to body 1 can be expressed as :
![$u'=\frac{u-v}{1-\frac{uv}{c^2}}$](https://tex.z-dn.net/?f=%24u%27%3D%5Cfrac%7Bu-v%7D%7B1-%5Cfrac%7Buv%7D%7Bc%5E2%7D%7D%24)
Speed of rocket 1 with respect to rocket 2 :
![$u' = \frac{0.4 c- (-0.3 c)}{1-\frac{(0.4 c)(-0.3 c)}{c^2}}$](https://tex.z-dn.net/?f=%24u%27%20%3D%20%5Cfrac%7B0.4%20c-%20%28-0.3%20c%29%7D%7B1-%5Cfrac%7B%280.4%20c%29%28-0.3%20c%29%7D%7Bc%5E2%7D%7D%24)
![$u' = \frac{0.7 c}{1.12}$](https://tex.z-dn.net/?f=%24u%27%20%3D%20%5Cfrac%7B0.7%20c%7D%7B1.12%7D%24)
![u'=0.625 c](https://tex.z-dn.net/?f=u%27%3D0.625%20c)
Therefore, the speed of rocket 1 according to an observer on rocket 2 is 0.625 c
Answer:
a luminous ball of plasma
Answer:
0.22 km/h
Explanation:
72 hours in 3 days
16/72 = 0.222222222
round to 0.22 km/h
For future reference, Distance/Time= Speed
Answer:
From the previous explanation Student No. 1 has the correct explanation
Explanation:
When the fluorescent lamp emits a light it has the shape of its emission spectrum, this light collides with the atoms of Nitrogen and excites it, so these wavelengths disappear, lacking in the spectrum seen by the observed, for which we would see an absorption spectrum
The nitrogen that was exited after a short time is given away in its emission lines, in general there are many lines, so the excitation energy is divided between the different emission lines, which must be weak
From the previous explanation Student No. 1 has the correct explanation
