MCAT Question of the Day
    •

    Q:

    		 Sam and Molly are working on a science project together, observing the movement of electrons. They have found the velocity of the electron 4 seconds into the experiment. Sam believes that he can use this information to determine the electron's location. Is Sam correct? Why or why not?
    		 

    A

    		 He is incorrect because the mass of an electron is always the same.

    B

    		 Sam is mistaken and we cannot know where the electron is.

    C

    		 He is correct because the electron follows a known path.

    D

    		 He is correct because electrons exhibit wave-like properties.
