The square plates of a 3000-pF parallel-plate capacitor measure 40 mm by 40 mm and are separated by a dielectric that is 0.29 mm thick and completely fills the region between the plates.
 
  What is the dielectric constant of the dielectric? (0 = 8.85  10-12 C2/N  m2)
  A) 61
  B) 56
  C) 50
  D) 45
  E) 67

Question 2

A 15-F capacitor is connected to a 50-V battery and becomes fully charged. The battery is removed and a slab of dielectric,
 
  having a dielectric constant of 5.0, is inserted between the plates and completely fills the space between them.
  (a) What is the capacitance of the capacitor after the slab is inserted?
  (b) What is the potential difference across the capacitor with the dielectric inserted.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.
