So we can know what is in space maybe weird or interesting stuff
Answer: 500 s
Explanation:
Speed
is defined as a relation between the distance
and time
:
![v=\frac{d}{t}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7Bt%7D)
Where:
is the speed of light in vacuum
is the distance between the Earth and Sun
is the time it takes to the light to travel the distance
Isolating
:
![t=\frac{d}{v}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bd%7D%7Bv%7D)
![t=\frac{1.5(10)^{11}m}{3(10)^{8}m/s}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B1.5%2810%29%5E%7B11%7Dm%7D%7B3%2810%29%5E%7B8%7Dm%2Fs%7D)
Finally:
![t=500 s](https://tex.z-dn.net/?f=t%3D500%20s)
Answer:
you absolute buffoon Use Ohms' Law: V = RI
V = (1x10^3)(5x10^-3) = 5 volts
Yes, this is in the range of normal household voltages.
Explanation:
The relationship between the number of visible spectral lines are identical for atoms .However they have unique wavelengths.
Option B
<u>
Explanation:</u>
A spectrum is a range of frequencies or a range of wavelengths. The photon energy of the emitted photon is equal to the difference between two states. For every atom there are quite many electron transitions and each has a energy difference.
This difference in wavelength causes spectrum .As each element emission spectrum is unique because each atom has different energy and causes uniqueness in the emission spectrum . Hence, due to the difference in energy it emits different wavelengths.
