A parallel-plate capacitor that has air between the plates is initially charged by being connected to a battery. With the battery still connected, one of the following changes is made. 1: The distance between the plates is doubled. 2: A dielectric with a dielectric constant 3 times that of air is inserted, completely filling the space between the plates. 3: Another identical, but initially uncharged, capacitor is placed next to the first so they are touching, effectively doubling the area of each plate.
(a) Rank these changes, from largest to smallest, based on the final potential difference across the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(b) Rank these changes, from largest to smallest, based on the final charge stored on the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(c) Rank these changes, from largest to smallest, based on the magnitude of the final electric field within the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(d) Rank these changes, from largest to smallest, based on the final energy stored by the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)

You throw a small rock straight up from the edge of a highway bridge that crosses a river. the rock passes you on its way down, 7.00 s after it was thrown. what is the speed of the rock just before it reaches the water 28.0 m below the point where the rock left your hand? ignore air resistance.
