Each letter of the alphabet is associated to a number (see below). Based on your name, determine the mass of the star assigned to you and answer the brief questions below. A,J,S=1 B,K,T=2 C,L,U=3 D,M,V=4 E,N,W=5 F,O,X=6 G,P,Y=7 H,Q,Z=8 I,R=9 1) Find the mass of your star (in solar units) by multiplying the number associated to FIRST letter of your first name by the number of the FIRST letter of your last name, and dividing the result by 10. (Example: if your first name starts with an M and your last name starts with a G, your star mass will be (4*7)/10 =2.8 solar masses). 2) Is your star cool, of intermediate temperature, or hot? 3) Will your star become a white dwarf, a neutron star, or a black hole? 4) Assuming that your star is in a binary system, what will happen?

A solenoid has [N] turns wound uniformly around a cylindrical core of length [L] cm and diameter [d] cm. The magnetic field inside and near the center of the solenoid is measured to be B =[B] × 10−2T. The current fowing through the solenoid = ……A. Given µ0 = 4 π X 10-7 T∙m/A {Hint: First find n=N/L, then use relation B=μ0 NI}
