Answer:
To find out which choice is not represented in the appropriate units, let's examine each one in turn:
1. Stress Strain = N/m² - Stress is measured in Newtons per square meter (N/m²), which is the unit of force per unit area. That's right.
2. Surface tension = N/m - Newtons per meter, or N/m, is the unit of force per unit length used to define surface tension. This is also accurate.
3. Energy= kg-m/sec - The unit of energy is joules (J), which is equal to kg·m²/s². The energy unit provided, kg·m/sec, is incorrect.
4. Pressure = N/m² - Newtons per square meter (N/m²) is the unit of force per unit area that represents pressure. This unit is accurate.
As a result, the following choice is not reflected in the appropriate unit:
The energy is expressed as kg-m/sec.
Energy ought to be communicated in
