The hysteresis loss for a specimen of iron weighing 15kg is equivalent at `300Jm^(-3)cycle^(-1)` Find the loss of energy per hour at 25 cycle `s^(-1)`. Density of iron is `7500kg m^(-3)`

Explanation

To solve the problem of calculating the hysteresis loss per hour for a specimen of iron, we can follow these steps:

### Step 1: Understand the given data
- Weight of the iron specimen (m) = 15 kg
- Hysteresis loss per unit volume (H) = 300 J/m³/cycle
- Frequency (f) = 25 cycles/s
- Density of iron (ρ) = 7500 kg/m³
