You throw a Frisbee of mass m and radius r so that it is spinning about a horizontal axis perpendicular to the plane of the Frisbee. Ignoring air resistance, the torque exerted about its center of mass by gravity is
   
  a.
  0.
   
  b.
  mgr.
   
  c.
  2mgr.
   
  d.
  a function of the angular velocity.
   
  e.
  small at first, then increasing as the Frisbee loses the torque given it by your hand.

Question 2

The graphs below show angular velocity as a function of time. In which one is the magnitude of the angular acceleration constantly decreasing?
   
  a.
 
  b.
 
  c.
 
  d.
 
  e.

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
