- AImpulse only
- BImpulse and pressure only
- CImpulse, temperature and pressure
- DGravitational potential
Explanation
Impulse (change in momentum, force x time) has both magnitude and direction, so it is a vector. Energy, power, pressure, temperature, and gravitational potential are all scalar quantities with magnitude only. Hence impulse only is the vector quantity.
