Answer:
300 nm
Explanation:
R = Gas constant = 8.314 J/molK
r = Atomic radii =
d = Atomic diameter =
At STP
T = Temperature = 273.15 K
P = Pressure = 100 kPa
= Avogadro's number =
The mean free path is given by
The answer that best represents the mean free path for gas molecules is 300 nm
The length by which the spring got stretched will be 0.08 m. The force is directly propotional to the distance by which the spring stretched.
<h3>What is spring force?</h3>The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is
F = kx
The given data in the problem is;
F is the spring force =200
K is the spring constant= 2500 N/m
x is the length by which spring got stretched =?
The stretch of the spring is found as;
Hence the length by which the spring got stretched will be 0.08 m.
