A spring scale shows a net force of 0.8 N acting on a 1.5-kg mass. What happens to the acceleration of the object if the net force is decreased to 0.2 N?
The acceleration decreases to a quarter of its original value, or about 2 13 m/s2
The acceleration decreases to a quarter of its original value, or about 0.13 m/s2
The acceleration increases to four times its orginal value, or about 0.13 m/s2
The acceleration increases to four times its original value, or about 2.13 m/s2

(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
