Physics 20.
Here are two sample calculation questions.
1. The hard disk drive in a computer spins at a rate of 7.20 E3 RPMs. If the disk has a radius of 8.26cm, what is the speed of the outer edge of the disk?
2. A 15.0 g solution in a test tube is placed in a centrifuge that spins at a rate of 2.50 E2 Hz . What is the centripetal force exerted on the solution if the radius of the circular motion is 12.0 cm?

A cell is like....
"A
cell is a ____________" This will be your main metaphor in a slideshow
that you will write. For each cell part
or organelle, you will pick another metaphor that fits within the main metaphor
and you will explain why you have chosen it. For example, If
a Cell is a City (that is the main metaphor) then the Nucleus is City Hall
because it controls everything that happens in the City.
You
may also use comparisons like a cell is like a factory, or a cell is like an
office building, or a cell is like a school.
Regardless
of what analogy you use, you need to pick one and come up with a theme, using
all 7 different cell parts or organelles.
Cell
membrane - outside
Cell
Wall – strength and structure
Cytoplasm
– what takes up the most space
Nucleus
– the brain
Chloroplast
– the fuel
Mitochondria
– the engine
Vacuoles
– storage
(Bonus
for using more than these!) If you
search the internet for cell parts or organelles, you can find several more
that are taught in higher level sciences.

A simile
for each the ____ is like the ______ because |

|
A separate slide
for each part |
The slide
should be easy to read and |
