Two carts with masses Of 400g and 200g move towards cach other in the same straight line. At some point the carts collide. If the force exerted by the large cart on the small one is 4N calculate the force exerted by the small cart in the big. (sorry to bother if anyone could help it would be so appreciated)

(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
