1a. Spheroidite steel is a good example of Metal Matrix
Composite material. What are the matrix material and the dispersed
phase acting as a reinforcing agent?
1b. Name one material that is commonly used as the fibers in
fiber reinforced composites.
2a. In metals increasing “imperfections” e.g. grain boundaries,
dislocations, vacancies in the material will increase or decrease
the resistivity of that material? Briefly explain why.
2b. Does the resistivity of a copper increase or decrease when
it is heated...

What would a comparison matrix look like between:
MySQL, MSSQL, Oracle, and SQLite
based on the following information:
current version, operating system, cost, written in, licensing,
graphical management tools, and maximum number of records
A composite of Al2O3 particles in an epoxy
matrix contains 10 wt.% Al2O3. What are the
upper and lower bounds on the elastic modulus of the composite?
Data: ρAl2O3 = 3.95 g/cm3 , EAl2O3 = 300 GPa,
ρepoxy = 2.0 g/cm3 , and Eepoxy = 500
MPa.

Put a ceramic mug and a metal pot or dish in the freezer and
wait for a half hour...
Now get the shower going as hot as it will go; really steam up
the bathroom. Keep the fan off and the bathroom door closed. After
the bathroom is good and steamy take the cold items from your
freezer into the bathroom. What do you observe in terms of
condensation? How does the condensation on the ceramic mug compare
with the...
the statement is true or false and then explain why.
In a comparison between the DNAs os related organisms such as
humans and mice, identifying the conserved DNA sequences
facilitates the search for functionally important regions.
it appears more and more ceramic and metal objects are being
replaced nowadays. These include : 1) household materials (some
ceramic bath tubs or floors are replaced with polymer materials )
2) metal pipes surrounding the house/ building become plastic pipes
3) even our lunch boxes nowdays are made of plastics instead of
metal . list one advantage for using polymers but not ceramic/
metals in each of the above mentioned 3 cases and the cited polymer
advantage in each...
