My process, which was incorrect, is as follows:

Isphere = 2/5(14)(0.120)^2
= 0.0806 kg*m^2


L = (I)(Omega)
= (0.0806kg*m^2)(0.600rad/s)
= 0.0484 kg*m^2/s

I even tried using Isphere is m(s/2)^2, and that was incorrect. What am I doing wrong? Thanks!

It says to fill in the following table, and says C=\v ( \ = wavelength symbol on here) where c = 10^8 m/sec and wants me to give my answers using scientific notation( how would i figure these out what would i have to do)? please help
also the website shows the ws Fill in the blank i tried to do this but was to hard please help this is the worksheet (www.chemadventure.com/5ws5.3.planckscon... (wont let me put the whole URL but add stantworksheet.doc to the end of con)

Example: wave = 3.9x10^-7m, v = 7.7x 10^14 s^1, e = 5.1x10^-19j (idk how to get those here r the problems

1. Fill wave and e given: v = 1.0x10^13 s^-1
2. fill in v and e given: 3.0x10^-4 m = wave
3. fill in wave and e given v= 2.0 x 10^22 s^-1
4. fill in v and e given wave = 2.0 x 10^ -2 m
5. fill in wave and e given: v = 1x 10^7 s^-1
6. fill in v and e given wave = 2.0x10^-10 m
7. fill in wave and e given v= 1.005 x 10^6 s^-1
8. fill in v and e given: wave = 9.052x 10^-6m

please help with this

A capacitor balance has on one side a mass M, while on the other side is a capacitor whose two plates are separated by a be a gap of variable width. When the capacitor is charged to a voltage V, the attractive force between the plates balances the weight of the hanging mass. Calculate the voltage neccesary to balance a mass of 20mg if the plate area is 40 cm^2 & the plate separation d is 1 mm. can someone help me out..

Please find a counterexample to the following:
note: S and T are subsets of R (set of all real numbers)

1. if set S is closed, then the closure of the interior of S = S

2. bd ( cl S ) = bd S

3. bd ( S union T ) = ( bd S ) union (bd T)

thanks so much
