For a specimen of iron weighing 15 kg the hysteresis loss is equivalent to `400 Jm^(-3)` /cycle. Calculate the loss of energy per hour at 60 cycle/ s. Take density of iron = `7,500 kg//m^3`

Explanation

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

### Step-by-Step Solution

1. **Identify Given Data**:
- Mass of iron specimen, \( m = 15 \, \text{kg} \)
- Hysteresis loss, \( q = 400 \, \text{J/m}^3/\text{cycle} \)
- Frequency of cycles, \( f = 60 \, \text{cycles/s} \)
