Answer:

d

Explanation:

Answer 2

Statement (A) : Impulse can be calculate it from the area under force time graph in a given interval of time.

Statement (B) : Impulse is a vector quantity

Here, both the statements are TRUE.

Detailed Discussion:

Impulse actually refers to momentum change of an object such that it can be represented as the product of force and time.

So, impulse can be calculated from Force-time graph as follows:

$\therefore I=\Delta P$

$\implies I = \displaystyle \int F \times dt$

$\implies I = Area \:under\:F-t\:graph$

So, statement A is true

Now, since force is a vector quantity, impulse will also be a vector quantity. Its direction will be in the direction of the applied force

So, statement B is also true

$\bf Both\:statements\:are\:correct$
