Text Solution

AI Generated Solution

To solve the problem of how much time is required to accumulate a total charge of 1 Coulomb from a body that emits \(10^9\) electrons every second, we can follow these steps: ### Step 1: Determine the charge of a single electron The charge of a single electron is given as: \[ e = 1.6 \times 10^{-19} \text{ Coulombs} \] ...
