A moving electron has `4.55 xx 10^(-25)` joules of kinetic energy. Calculate its wavelength (mass `= 9.1 xx 10^(-31) kg and h = 6.6 xx 10^(-34) kg m^(2) s^(-1)`)

Explanation

To solve the problem of calculating the wavelength of a moving electron with a given kinetic energy, we can follow these steps:

### Step 1: Identify the given values
- Kinetic Energy (KE) = \( 4.55 \times 10^{-25} \) joules
- Mass of the electron (m) = \( 9.1 \times 10^{-31} \) kg
- Planck's constant (h) = \( 6.6 \times 10^{-34} \) kg m²/s

### Step 2: Use the kinetic energy formula to find the velocity
