Q. A parallel-plate capacitor is formed from two 2.20 2.20 electrodes spaced 2.30 apart. The electric field strength inside the capacitor is 1.00 . What is the charge (in nC) on each electrode?
Q. Consider a 70-kg woman who has a total foot imprint area of 400 cm2. She wishes to walk on the snow, but the snow cannot withstand pressures greater than 0.5 kPa. Determine the minimum size of the snowshoes needed (imprint area per shoe) to enable her to walk on the snow without sinking.
