Answer

given,

speed of the fastest runner = 6.2 m/s

speed of the slower runner = 5.5 m/s

Assume, we need to calculate  time when both the runner meet for the first time.

distance cover by the fast runner = distance cover by the slow runner

  6.2 t = 5.5 t + 200

   0.7 t = 200

      t = 285.71 s

time after which both the runner meet.

Distance they covered after starting

D = s x t

D = 6.2 x 285.71

D = 1771.43 m.

now, calculating the second time both will meet.

they will take double time to meet again

 t' = 2 x 285.71

t '= 571.42 s

The element Ne, neon, has ____ (number) complete shells having its ____ electrons in second _____.
KatRina [158]

Answer:

2, 8 and shell

Explanation:

Neon as atomic number 10. Since for each shell, electrons equal 2n².

When n = 1, 2n² = 2(1)² = 2

When n = 2, 2n² = 2(2)² = 8

So it fills both the first and second shell with 2 and 8 electrons respectively to achieve its stable atomic state. The rest of the 8 electrons go into the second shell because the first shell has achieved its stable dual configuration of two electrons. The next shell requires a maximum of 8 electrons to achieve stability so, the remaining electrons fill it up to achieve the stable octet configuration.
