Two identical particles, each with a mass of 2.0 g and a charge of 25 nC, are released simultaneously from rest when the two are 4.0 cm apart. What is the speed of either particle at the instant when the two are separated by 10 cm?
 a. 7.3 m/s
  b. 9.8 m/s
  c. 9.2 m/s
  d. 6.5 m/s
  e. 4.6 m/s

Question 2

A 60-C charge is held fixed at the origin and a 20-C charge is held fixed on the x axis at a point x = 1.0 m. If a 10-C charge is released from rest at a point x = 40 cm, what is its kinetic energy the instant it passes the point x = 70 cm?
 a. 9.8 J
  b. 7.8 J
  c. 8.8 J
  d. 6.9 J
  e. 2.8 J

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
