The assume that goes with the inquiry demonstrates the wavelenghts of the photons transmitted by Balmer arrangement change , from vitality levels (n) 3, 4, 5, and 6 to the vitality level (n) 2, in hydrogen particles.
These are the values shown in the figure
Transition wavelength of the photon emitted
nm
from n=3 to n=2 656<------ this is the value requested
from n=4 to n=2 486
from n=5 to n=2 434
from n=6 to n=2 410
The wavelength of a photon discharged from the n = 3 shell in hydrogen is the primary information of the table, i.e 656 nm.
Using the conversion factor from nm to m that results is :
656 nm * 1 m / (10^9 nm) = 656 * 10 ^ -9 m.
Hope this helps
Answer:
We need to perform a condition of balance along a rod in which we can measure distances. Finally, find the weight ratio and measure the weight of one of the masses in order to find the weight of the second.
Explanation:
We need to see this problem using a sketch with a class 1 lever. And some numerical values to understand and how to make the proper calculations.
Let's say that we have a body in the form of a beam 1 meter long, then we put the two masses in each of the ends of the beam under the beam, we place the fulcrum and move up to the beam to obtain a horizontal position when horizontal position is reached the beam will be in balance.
Then we perform a sum of moments around the pivot point or fulcrum since we know the distances, we can find the mass relation in the condition of balance. For this example the ratio corresponds to M1 is 2.33 times heavier than M2.
The ultimate fate of a star depends on its mass.
A massive star ends with a violent explosion called a supernova.
The matter ejected in a supernova explosion becomes a glowing supernova remnant.
Toward the end of its life, a massive supergiant star
has a central iron core, surrounded by a shell where
silicon is being fused to iron, surrounded by a shell
where oxygen is being fused, surrounded by a shell where
carbon is being fused, surrounded by a shell where helium is
being fused, surrounded by a shell where hydrogen is
being fused.
