The electric current in an X-ray tube (from the target to the filament) operating at `40 kV `is `10 mA`. Assume that on an average, 1% of the total kinetic energy of the electrons hitting the target are converted into X-rays(a) What is the total power emitted as X-rays and (b) how much heat is produced in the target every second?

Explanation

To solve the problem step by step, we will break it down into parts (a) and (b) as follows:

### Part (a): Total Power Emitted as X-rays

1. **Given Data**:
- Voltage (V) = 40 kV = \(40 \times 10^3\) V
- Current (I) = 10 mA = \(10 \times 10^{-3}\) A
- Conversion efficiency to X-rays = 1% = \(0.01\)
