A 1.5-kg mass attached to spring with a force constant of 20.0 N/m oscillates on a horizontal, frictionless track.
 
  At t= 0, the mass is released from rest at x= 10.0 cm. (That is, the spring is stretched by 10.00 cm.)
  (a) Determine the frequency of the oscillations.
  (b) Determine the maximum speed of the mass. Where does the maximum speed occur?
  (c) Determine the maximum acceleration of the mass. Where does the maximum acceleration occur?
  (d) Determine the total energy of the oscillating system.
  (e) Express the displacement as a function of time.

Question 2

If in a double-slit experiment the wavelength of light is increased, which of the following happens to the interference pattern shown on the screen?
 
  A)
 
  The maxima get further apart.
  B)
 
  The maxima stay at the same position.
  C)
 
  The minima and maxima stay at the same position.
  D)
 
  The minima get closer together.
  E)
 
  The minima stay at the same position.

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.
