The carbon dioxide laser is one of the most powerful developed. The energy difference between the two laser levels is 0.117 eV. Determine the frequency and wave- length of the radiation emitted by this laser. In what portion of the electromagnetic spectrum is this radiation?
How much energy is stored in an 8.00 - $\mu$ F capacitor whose plates are at a potential difference of $6.00 \mathrm{V}$ ?
If the potential due to a point charge is $5.00 \times 10^{2} \mathrm{V}$ at a distance of $15.0 \mathrm{m},$ what are the sign and magnitude of the charge?
The voltage across a membrane forming a cell wall is $80.0 \mathrm{mV}$ and the membrane is $9.00 \mathrm{nm}$ thick. What is the electric field strength? (The value is surprisingly large, but correct.) You may assume a uniform electric field.
