Based on the collision theory, which property of reactions
(collision frequency, energy, orientation, etc) do you think is the
most important? Discuss two ways by which this property can be
influenced to change the rate of reaction.
1.What is the unit for kinetic energy?
2.A collision in which kinetic energy is conserved is called
what?
3. It takes no work to hold a cheerleader in the air, as shown
here. If no work is done by the cheerleaders, why do they
eventually tire?
A.The concept of work, as it apples in physics, does not apply
to any process that involves people.
B.Their bodies expend chemical energy as their muscles
function; this is "hard work," but not the...
How do chemical reactions play a role in energy transfer?
a) Energy from the breakdown of glucose and other molecules in
animals is released as ATP, which transfer energy to other
reactions.
b) Energy from the breakdown of glucose and other molecules in
animals is released in the form of NADP, which transfers energy to
other reactions.
c) Energy is released in the form of glucose from the breakdown of
ATP molecules. These ATP molecules transfer energy from one
reaction...
Theory of enzymes:
True or False:
___ Enzymes catalyze reactions by increasing the reaction free
energy
___ Enzyme are remarkable for their substrate specificity.
___ Enzyme can convert light energy into chemical or mechanical
energy
___ Catalytic residues in enzymes can include amino acid side
chains, RNA bases, and other organic cofactors
___ Michaelis-Menten kinetic theory only applies to enzymes with
single substrates
___ Enzymes bind transition-state analogs more tightly than
substrates
___ At high substrate concentration, reactions are rare-limited...
when you would want to use collision theory over transition
state theory and when you would want to use transition state theory
over collision theory. Provide examples for both. Use literature
citations to support your information. Follow the same formatting
as requested in the group project reports.
Which property of secure hash
functions—one-way, weak collision-resitance, or strong
collision-resistance—make them useful in the context of password
security?
What is a password dictionary? Can it be used to
improve password security?
What is the motivation for limiting the password age? In
particular, why would you enforce a maximum age? Why would
you want to set a minimum age?
Psychoanalyst Erich Fromm created a theory of character
orientation, which included what he referred to as a ‘marketing
personality’. This is an example of self-objectification -
regarding the human as an object and instrument. Do you think that
increased technological complexity makes people more or less likely
to self-objectify? Why?

Pick an energy drink.( Tell us which one.) Do you think this energy
drink provides energy (calories) or stimulant(like caffeine)? If
yes, what is the source of the energy (be specific- look at the
ingredients of the energy drink).If not, why not?
What are the claims of this energy drink?Do you think they are
valid? Why or why not?
