Observe the details of these three images. What inferences can you make about the changes in the logs? The law of conservation of mass applies to ALL physical and
chemical changes. How are these three images different? What happens to the matter stored within
the logs as the fire burns?

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

(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

Apair of 10μf capacitors in a high-power laser are charged to 1.7 kv.a. what charge is stored in each capacitor? b. how much energy is stored in each capacitor?
