A particle with a charge of +4.0 C has a mass of 5.0 g. What magnitude electric field directed upward will exactly balance the weight of the particle?
 
  A) 4.1  104 N/C
  B) 8.2  104 N/C
  C) 4.4  104 N/C
  D) 1.2  104 N/C
  E) 5.1  104 N/C

Question 2

A geophysicist measures the magnetic force on a proton that is moving vertically downward at a point 1.996 km/s at the earth's equator. At that location, the earth's magnetic magnetic field is horizontal and has a strength of 0.40  10-4 T.
 
  What are the magnitude and direction of the force she will measure? (e = 1.60  10-19 C)

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
