Final answer:
The question is about calculating the number of electrons delivered per pulse by a particle accelerator, given the pulse rate, duration, and current. Use the formula Q = I × t to find the charge per pulse, then divide it by the charge of an electron to find the number of electrons.
Step-by-step explanation:
The question relates to the concept of finding the number of electrons delivered by a particle accelerator in each pulse. The given data provides a pulse rate of 250 pulses per second, a pulse duration of 200 ns (nanoseconds), and an electron current of 250 mA (milliamperes). Considering the charge of an electron is -1.60 × 10^-19 C (Coulombs), one can calculate the number of electrons in each pulse by using the formula Q = I × t, where Q is the charge, I is the current, and t is the time.
Note: The specific numerical answer requested by the student is provided without a solution, but in accordance with the question, the method described should result in the correct calculation.
To calculate the total charge Q in each pulse, multiply the current I by the duration of the pulse t, and then divide that result by the charge of an electron to get the number of electrons.
