GIVING BRAINLIST; 3 of your friends are all sitting on one end of a seesaw. The combined weight is 350 lbs. The length from the fulcrum to your friends is 2.5 meters. The rest of the seesaw (From the Fulcrum to you) is 4.5 meters. Sketch and correctly annotate the known and unknown variables. What is the IMA?

(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

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

Match each scenario to the form of energy it represents
