Scientists generally agree that Earth is getting warmer due to what's called the greenhouse effect. A greenhouse used for plants stays warm because sunlight and heat coming through the glass roof are mostly trapped. The heat doesn't radiate back into the atmosphere ...

a) Determine the capacitance, in pF, of a paper-filled parallel-plate capacitor (dielectric constant=3.70) having a plate area of 5.40cm2 and plate separation of 590 µm. Use 8.85 x 10-12 F/m for εo, the permittivity of free space. For this I got 2998.53x10-2 b) ...
