Consider the quantities pressure, power, energy, impulse gravitational potential, electric charge, temperature, area. Out of these, the only vector quantities are a) impulse, pressure, and area b) impulse and area c) area and gravitational potential d) impulse and pressure

Answer: The correct answer is b) impulse and area

We know that impulse is defined as $J = F \cdot \Delta t =\Delta p$, where $F$ is force, At is time length, and $\Delta p$ represents momentum change. Impulse is a vector quantity because $Delta p$ is a vector quantity. The area can alternatively be thought of as a vector whose direction is perpendicular to its plane.
