consider an air-filled parallel plate capacitor with plate area A and gap width d. the plate charge is Q. After the capacitor has been fully charged to Q, the battery is disconnected. Then the gap is filled with a dielectric with dielectric constant k. what is the voltage within the gap in the presence of the dielectric

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

You are a sales representative for a company that makes a new alternate fuel for vehicles. you have prepared a presentation for the environmental engineers to sell your new product. what question do you expect the audience to ask regarding whether the new fuel will cause less damage to the environment? a. do we have to change any parts of the vehicle to use this alternate fuel? b. will the vehicles get better fuel mileage with the alternate fuel? c. how much greenhouse gas does your fuel produce compared with current fuel sources? d. is the alternate fuel more expensive than fossil fuel?
