A beam of electrons is accelerated from rest and then passes through a pair of identical thin slits that are 1.35 nm apart. You observe that the first double-slit interference dark fringe occurs at ±15.0 ∘ from the original direction of the beam when viewed on a distant screen. Through what potential difference were the electrons accelerated?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
