Mitch holds a pumpkin at waist level. How can he add potential energy to the pumpkin?

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present

What is the equation for electrical work?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
