A very long wire carries a uniform linear charge density of 7.0 nC/m. What is the electric field strength 16.0 m from the center of the wire at a point on the wire's perpendicular bisector? (0 = 8.85  10-12 C2/N  m2)
 
  A) 7.9 N/C
  B) 3.9 N/C
  C) 0.49 N/C
  D) 0.031 N/C

Question 2

The coefficient of volume expansion of olive oil is 0.68  10-3 K-1. A 1.00-L glass beaker is filled to the brim with olive oil at room temperature. The beaker is placed on a range and the temperature of the oil and beaker increases by 25 C.
 
  As a result, 0.0167 L of olive oil spill over the top of the beaker. What is the coefficient of linear expansion of the glass?
  A) 1.0  10-6 K-1
  B) 2.0  10-5 K-1
  C) 4.0  10-6 K-1
  D) 3.0  10-5 K-1
  E) 1.0  10-5 K-1
