A charge of 1.0  10-6 C is located inside a sphere, 1.25 cm from its center. What is the electric flux through the sphere due to this charge? (0 = 8.85  10-12 C2/N  m2)
 
  A) 0.028 N  m2/C
  B) 0.11 N  m2/C
  C) 8.9 N  m2/C
  D) It cannot be determined without knowing the radius of the sphere.

Question 2

Consider the motion of a 1.00-kg particle that moves with potential energy given by
  U(x) = (-2.00 Jm)/x + (4.00 Jm2)/x2. Suppose the particle is moving with a speed of 3.00 m/s when it is located at x = 1.00 m.
 
  What is the speed of the object when it is located at x = 5.00 m?
  A) 2.13 m/s B) 4.68 m/s C) 3.00 m/s D) 3.67 m/s

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
