That's <em>false.</em> According to current atomic theory and quantum mechanics, an electron is always PROBABLY SOMEWHERE in a fuzzy foggy area around the nucleus of the atom, and that's all we can <u>ever</u> say about it. There's no way to even TELL where the electron is, even if we <u>had</u> the technology to see things that small.

Answer:
2.80N/m
Explanation:
Given data
mass m= 56kg
perios T= 11.2s
The expression for the period is given as
T=2π√m/k
Substitute
11.2= 2*3.142*√56/k
square both sides
11.2^2= 2*3.142*56/k
125.44= 351.904/k
k=351.904/125.44
k= 2.80N/m
Hence the spring constant is 2.80N/m
