2. On Tuesday (12 June 2018), we have shown that a charge moving at velocity v generates a mag- netic field that can be written as where E is the electrostatic field generated by that point charge. Look up the values of the permit tivity constant Eo and permeability constant uo, both in SI units, and show that where c3 x 10*m/s is the speed of light. Note: You must show how you convert the units (10 points)

9. On Thursday (June 6th), we have shown that the magnetic field at the central axis of an infinitely long solenoid is simply B HoIn with / the current passing through the wire and n the coil density (number of turns per unit length). If the solenoid is of a finite length L, the result of the magnetic field is found to be B uoln(sin02- sin 01), where 0-x 01 arctan -X 02arctan a considering 0 X I Make sketches...

K-means clustering Problem 1. (10 pts) Suppose that we have the gene expression values for 5 genes (G1 to G5) under 4 time points (t1 to t4) as shown in the following table. Please use K-Means clustering to group 5 genes into 2 clusters based on Euclidean distance. Find out the final centroids and their affiliated genes. The initial centroids are c1=(1,2,3,4) and c2=c(9,8,7,6). Please write down your algorithm step by step. Result without steps won't get points. t1 t2...

**Please Show All The Steps**
As I mentioned in the class assume that we have a GaAs (Gallium
Arsenide) sample which was doped with excessive As to produce a
resistivity of 0.05 Ωm. Owing to the presence of an unknown
acceptor impurity the actual resistivity was 0.06Ωm, the sample
remaining n-type. What were the concentrations of donors and
acceptors present?
(Please take μe=0.85 m2/Vs and assume that all impurity atoms
are ionized)
