The correct answer is option 4, linear momentum.

Impulse is defined as the change in momentum, and momentum is a vector quantity that depends on both an object`s mass and its velocity. The formula for momentum is given by the product of mass and velocity. In SI units, momentum is measured in kilogram-meters per second (kg·m/s), which represents the quantity of motion or inertia an object possesses.

Option 1, pressure, is defined as the force per unit area and is measured in pascals (Pa) or newtons per square meter (N/m²). The dimension of pressure is force divided by area, not the same as impulse.

Option 2, angular momentum, is a vector quantity that depends on an object`s moment of inertia and its angular velocity. Angular momentum is measured in kilogram-meters squared per second (kg·m²/s), which represents the rotational equivalent of linear momentum. The dimension of angular momentum is not the same as impulse.

Option 3, work, is defined as the product of force and displacement and is measured in joules (J). The dimension of work is not the same as impulse.

Therefore, the dimension of impulse is the same as that of linear momentum,
