Write the derived units of the following :
(a) Speed , (b) Force , (c )Work , (d) Pressure

Explanation

To find the derived units of speed, force, work, and pressure, we will use the definitions and relationships between fundamental and derived units. Let's go through each one step by step.

### Step 1: Speed
- **Definition**: Speed is defined as the distance traveled per unit time.
- **Fundamental Units**:
- Distance is measured in meters (m).
- Time is measured in seconds (s).
- **Derived Unit**:
