Weighing a copper atom in an electrolysis experiment. A standard experiment involves passing a current of several amperes through a copper sulfate solution (CuSO4) for
a period of time and determining the mass of copper
plated onto the cathode. If it is found that a current of
1.00 A flowing for 3600 s deposits 1.185 g of copper,
find (a) the number of copper atoms deposited,
(b) the weight of a copper atom, and (c) the molar
mass of copper.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off
