6. nicholas made time measurements of waves in a wave
tank. the diagram below shows two of his timed stopwatch
readings for waves. based on the evidence, what is the
frequency of these waves? (frequency= number of
cycles/time) *
o a.25
o b.45
o c. 0.5 hz
o d. 2 hz

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Which of the following are appropriate acceleration units?
