If the work function of a metal surface is 2.20 eV, what frequency of incident light would give a maximum kinetic energy of 0.25 eV to the photoelectrons ejected from this surface? (1 eV = 1.60  10-19 J, h = 6.626  10-34 J  s)
 
  A) 2.50  1014 Hz
  B) 3.53  1014 Hz
  C) 5.92  1014 Hz
  D) 2.05  1014 Hz
  E) 1.02  1014 Hz

Question 2

A 6.0-F air-filled capacitor is connected across a 100-V potential source (a battery). After the battery fully charges the capacitor, it is left connected and the capacitor is immersed in transformer oil, which has a dielectric constant of 4.5.
 
  How much additional charge flows from the battery onto the capacitor during this process?
  A) 1.2 mC B) 2.1 mC C) 2.5 mC D) 1.7 mC

Malaria was not eliminated in the United States until 1951. The term eliminated means that no new cases arise in a country for 3 years.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

The most dangerous mercury compound, dimethyl mercury, is so toxic that even a few microliters spilled on the skin can cause death. Mercury has been shown to accumulate in higher amounts in the following types of fish than other types: swordfish, shark, mackerel, tilefish, crab, and tuna.

The average human gut is home to perhaps 500 to 1,000 different species of bacteria.

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.
