PHY 2005
Final Exam
Name (print):
April 30, 2009
Signature:
On my honor, I have neither given nor received unauthorized aid on this examination.
YOUR TEST NUMBER IS THE 5-DIGIT NUMBER AT THE TOP OF EACH PAGE.
(1) Code your test number on your pink answer sheet (use 76–80 for the 5-digit number). Code your name
on your answer sheet. Darken circles completely. Code your UF ID number on your answer sheet.
(2) Print your name on this sheet and sign it also.
(3) You will receive one point for each correct answer and zero points for an incorrect answer or no answer.
(4) Use a number 2 pencil on the answer sheet. Do not make any stray marks, or the answer sheet may not be read
properly.
(5) “X” is never the correct answer.
Useful Equations:
1 km = 103 m 1 cm = 10−2 m
1 mm = 10−3 m
1 nm = 10−9 m
1 N = 1 kg m/ s2
1 J = 1 N m = 1 kg m2 / s2
1 W = 1 J/s
1 V = 1 J/ C
1 F = 1 C/ V
1 A = 1 C/ s
k = 1/4π²0 = 9×109 N m2 / C2
²0 = 9×10−12 C2 / N m2
µ0 = 4π×10−7 T m/ A
c = 3×108 m/s
e = 1.6×10−19 C
