What is the increase of current when 15 V is applied to 10000 ohm. rheostat, which is adjusted to 1000-ohm value?

The plum pudding model of the atom state that ?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

(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
