A sheet of mica is inserted between the plates of an isolated charged parallel-plate capaci- tor. Mica is a transparent mineral that comes naturally in thin sheets, and is an excellent dielectric. Which of the following statements is true? 1. The capacitance decreases. 2. The charge on the capacitor plates de- creases. 3. The electric field between the capacitor plates increases. 4. The energy of the capacitor does not change. 5. The potential difference across the capac- itor decreases 015 10.0 points In order to store more energy in a parallel- plate capacitor whose plates differ by a fixed voltage. what change would you make in the plates?

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
