# Question 4

a)

The polymers look pretty globular. They all have 100 monomers and we see that they are never really further than 10 monomer units from the origin.

b)

I assumed here that when it asked how many simulations actually met the mean value you wanted us to use the mean value we calculated in 3 not the experimental ones we have above because the elements of the experimental ones are not even integers.

c) The root mean squared end to end distance is a better representation of length than the average end to end vector because of the symmetry of the end to end vectors. This causes the average to be zero even tho practically no polymer has end to end distance 0. Thus it is better to use the root mean squared end to end distance as a measure of the extent of a polymer because it will give us something similar to the length of a polymer with respect to distance from the origin. Then because the length is always positive we get a distribution of the extent of each polymer and dont get any cancelations from negative terms. We also saw above that practically no polymers actually meet the mean value so it is still quite unlikely.

d)

This answer is consistent with the scaling we calculated in 3d! because all of our values are quite close to the square root of length. The square roots of the different lengths are , 10, ~22.36, ~31.62 which are all very similar to our values.
