The current flowing through the X-ray tube which is operating at 25 kV is 1 mA. Calculate the number of electrons hitting target per second . Also, find the energy falling on the target per second.

Explanation

To solve the problem, we need to calculate two things: the number of electrons hitting the target per second and the energy falling on the target per second.

### Step-by-Step Solution:

1. **Convert Given Values:**
- Voltage (V) = 25 kV = 25 × 10^3 V
- Current (I) = 1 mA = 1 × 10^-3 A
