Identify the vector quantity from the following a) Heat b) Angular momentum c) Time d) Work

To identify the vector quantity from the given options, we need to understand the definitions of vector and scalar quantities.

Vector quantities have both magnitude and direction, while scalar quantities only have magnitude.

1. Heat - Scalar quantity (it has magnitude but no direction).
2. Angular Momentum - Vector quantity (it has both magnitude and direction).
3. Time - Scalar quantity (it has only magnitude and no direction).
4. Work - Scalar quantity (it has magnitude but no direction).

Final Answer

The vector quantity from the options provided is b) Angular momentum.
