Body A is at `30^(@)C` and a similar body B is at `70^(@)C`. Find the equilibrium temperature.

Explanation

To find the equilibrium temperature when two bodies at different temperatures come into contact, we can use the formula for equilibrium temperature. Here’s a step-by-step solution:

### Step 1: Identify the temperatures of the bodies
- Body A is at \( T_A = 30^\circ C \)
- Body B is at \( T_B = 70^\circ C \)

### Step 2: Use the formula for equilibrium temperature
For two bodies with the same mass and specific heat, the equilibrium temperature \( T_{eq} \) can be calculated using the formula:
