fuck this shit, havent had a science class since high school, but have to take this gen ed physics class in order to graduate this semester. BULLSHIT m8s! i really doubt anyone wants to do these for me, but i figured id just throw it out there since i know we got some smart junkies in here (even though a 12 yr old could probably do half of these)


Problems

Note: Show all you work CLEARLY including all equations, conversion factors, and units.

1. (1 pt) Use powers of ten notation and proper units to rewrite the following quantities: (a) 0.05 micrometer (b) 8 gigabytes (c) 1200 nanoseconds (d) size of a virus = 0.0000001 m.


2.  (1 pt) The world’s highest waterfall is Angel Falls in Venezuela at 979 meters. Express its height in feet and in miles.


3.  (1 pt) density=mass/volume. Mercury is a liquid metal with a density of 13.6 g/cm3. What is the mass of 10.0 cm3 of mercury?


4.  (1.5 pts) density=mass/volume. What volume of aluminum (density = 2.10 g/cm3) would be needed to balance a 5.00 cm3 sample of lead (density = 11.4 g/cm3) on a two-pan laboratory scale? If the aluminum is shaped into a cube, what is the length of each side of the cube (volume = (side)3)?
