Answer:
They form an ionic bond by exchanging two electrons.
Explanation:
The Balmer light series comes under the visible light.
<u>Explanation:</u>
The transition of electrons from higher to energy level with 2 as principal quantum number results in the spectral emission lines of hydrogen atom and this series of lines are known as Balmer series.
Mostly, these lines has the wavelength of more than 400 nm but lesser than 700 nm. Generally of the four categories namely, 410, 434, 486, 656 nm which comes under the type of visible light. So, it can be concluded that the Balmer series light falls under visible light.
In astronomy, Balmer lines occur in various stellar (celestial or astronomical) objects due to the higher content of hydrogen in the universe. Therefore, they are commonly seen and relatively strong when compared to other element lines.
Note: nm is nanometer (one billionth of a meter in length)
The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
<h3>What is heating and cooling?</h3>
Heating is the process by which the temperature of a place or substances or object is increased.
Cooling Is the process of lowering the temperature of a substance or object by using conditioners or by freezing .
Therefore, The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.

The distance to the water is the same for both ... call it s meters
They both take 1.6 s to reach the water ... so t = 1.6 seconds
They both step off the bridge ... so both have an initial vertical velocity is 0 m/s
Just consider the vertical motion and take DOWN as the positive direction
a = 9.8 m/s²
s = v(i)t + (1/2)at²
s = 0 + (1/2) * 9.8 * 1.6²
s = 12.5 m ←←← Edit: Forgot to say ... that's how high the bridge is above the water
Now get the time it takes the first jumper to reach 1.8 m:
s = v(i)t + (1/2)at²
1.8 = 0 + 4.9t²
t = 0.61 s
so when the 2nd person jumps it takes the first person another 1.6 - 0.61 = 0.99 s to reach the water
Now find how far the 2nd jumper falls in 0.99 s:
s = 0 + 4.9 * 0.99²
s = 4.8 m
so the separation distance between the two jumpers when the 1st jumper hits the water is 12.5 - 4.8 = 7.7 m
