Sure, I'd be happy to help with your homework. To calculate the number of electrons passing a point in the wire in 10 minutes when the current is 5A, we can use the formula I = Q/t, where I is the current, Q is the charge, and t is the time. Rearranging the formula to solve for Q, we get Q = I*t. Plugging in the given values, we get Q = (5A)(10min) = 50C.

For the second part, we can use the formula Q = I*t to calculate the charge flowing along the beam each minute. Plugging in the given values, we get Q = (1.2mA)(1min) = 0.0012C. To calculate the number of electrons passing along the beam each minute, we can use the fact that 1C of charge is equivalent to 1.6x10^19 electrons. Therefore, the number of electrons passing along the beam each minute would be (0.0012C)(1.6x10^19 electrons/C) = 1.92x10^16 electrons. I hope this helps!
