Answer:
The correct answer is (2). Among the pairs, angular acceleration and angular velocity have different units.
Explanation:
- The temporal rate at which angular velocity changes is known as angular acceleration. The standard unit of measurement is radians per second per second.
- Rotational acceleration is another name for angular acceleration. It is a numerical representation of the variation in angular velocity over time.
- It is expressed as, α = dω/dt
- Angular acceleration is used to study the motion of rotating objects like the wheel, fan, and earth.
- The rotation rate, which refers to how quickly an item rotates or circles in relation to another point, is measured vectorially by angular velocity.
- Angular velocity can be defined as the speed at which an item rotates or revolves around an axis. The Greek letter omega (occasionally ) stands for angular velocity. The SI unit for angular velocity is radians per second because it is expressed as an angle per unit of time.
- ω = dθ/dt
- On the other hand, the SI unit of Torque and Work are the same i.e. Nm, Stress and Bulk Modulus both have N/m² as SI units while Surface tension and spring constant have N/m as their SI units.
Thus, the pair that has different units is Angular acceleration and angular velocity.
