Two bodies have the same heat capacity. If they are combined to form a single composite body, show that the equivalent specific heat of this composite body is independent of the masses of the individual bodies.

Explanation

To solve the problem of finding the equivalent specific heat of a composite body formed by two bodies with the same heat capacity, we will follow these steps:

### Step 1: Define the heat capacities of the two bodies
Let:
- Body 1 has mass \( m_1 \) and specific heat \( s_1 \).
- Body 2 has mass \( m_2 \) and specific heat \( s_2 \).

Since the heat capacities are equal, we have:
