Compare and contrast the cigarette industry in the 20th century
with the vaping industry today. -Would you support ban on
advertising vaping? -Should the vaping industry undergo the same
public policy restrictions and taxations that the cigarette
industry went through in the past? -Explain how the vaping novelty
affect young people health and project effective policies to
minimize the nicotine consumption in the next 5-10 years.
In the early part of the 20th century, Niels Bohr proposed a
model for the hydrogen atom that explained the experimentally
observed emission spectrum for hydrogen.
a. List and describe two of the assumptions that Bohr made in
his model for the hydrogen atom.
b. List and describe two limitations of the Bohr mode
There was much progress in nursing during the early to middle
part of the 20th century (1900 through the late 1930s). After
reading the textbook and the lesson for this week, describe one
area of change in nursing during that time period that intrigues
you. Discuss how that area could be applied today.

One of the major developments in late 20th and early 21st
century is the IT revolution (emergence of computers and internet).
Based on your knowledge as the word citizen (which means you don’t
need to know any specific technological knowledge), describe how
you think the IT Revolution did affect the cost curves of a typical
company, in a sector you choose. Explain your view.
In the early 20th century, the French Canadian microbiologist
Félix d’Hérelle used a virus called a bacteriophage (“phage”) to
successfully treat some diseases caused by bacteria, such as
dysentery and cholera. Subsequent experiments with “phage therapy”
yielded mixed results; however, and enthusiasm quickly
waned—especially once antibiotics became available in the 1940s.
The therapy is not currently approved in the United States.
Phage therapy involves obtaining a pure culture of a
disease-causing bacterium and exposing samples of the culture to
different...
Bad Bad Benny: A True Story (Identifying Controls for a System)
In the early 20th century, there was an ambitious young man named
Arthur who started working at a company in Chicago as a mailroom
clerk. He was a hard worker and very smart, eventually ending up as
the president of the company, the James H. Rhodes Company. The firm
produced steel wool and harvested sea sponges in Tarpon Springs,
Florida for household and industrial use. The company was very...
Early 20th-century physicist Niels Bohr modeled the hydrogen
atom as an electron orbiting a proton in one or another
well-defined circular orbit. When the electron followed its
smallest possible orbit, the atom was said to be in its ground
state. (a) When the hydrogen atom is in its ground state, what
orbital speed (in m/s) does the Bohr model predict for the
electron? m/s (b) When the hydrogen atom is in its ground state,
what kinetic energy (in eV) does...
Compare and contrast the second industrial revolution (late nineteenth century to the early twentieth century) to the first industrial revolution (late eighteenth century to the early nineteenth century).
