Answer
given,
D = 50 mm = 0.05 m
d = 10 mm = 0.01 m
Force to compress the spring




F = 3160 N
stress correction factor from stress correction curve is equal to 1.1
now, calculation of corrected stress


= 442.6 Mpa
The tensile strength of the steel material of ASTM A229 is equal to 1300 Mpa
now,



since corrected stress is less than the
hence, spring will return to its original shape.

Answer:

Explanation:
The charge of a single electron is:

If a droplet contains N electrons, then its charge would be:

In this case, the droplet has
N = 6
electrons, so its total charge is

Answer:
Work function of the metal is 3.24 eV.
Explanation:
It is given that,
Wavelength, 
Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :



Since, 
So, W = 3.24 eV
So, the work function of the metal is 3.24 eV. Hence, this is the required solution.
