Sorry for writing the incomplete question. But yeah..it is how much power do your 30, 60, 90 watt light bubls use when connected to icelandic electrical sockets?

Physics
Iceland uses a voltage of 220v instead of of the US 110v. So you fly to Iceland with a box of bulbs ,that has been assorted with 30, 60 and 90 Watt light bulbs.U connect it through icelandic electrical socket. The fact that u 'll actually be using AC current will affect ne...

An air filled parallel plate capacitor has plates of area 0.0406 m^2 and seperation of 2.5*10^-6 m. a)What is the capacitence for the setup? b)Our capacitor is connected to a 550 v battery, how much energy is stored in the capacitor? c) If -1 mJ of work is performed by the cap...

Physics
hey Mr. Bob I was just wondering why did u take the charge of nucleus +e instead of 3e which is unclear to me..also we gotto find the total force on valence electron ie from both nucleus and the two electrons..am i correct....if not can u help me out..
