Question

Which quantity has both a magnitude and a

Answer 1

(2) impulse is a vector quantity. Energy has no direction, nor does power. Work is a dot product of vector quantities, which makes it a scalar.

Answer 2

Answer:

Impulse is a vector quantity.

Explanation:

The force acting for a very short interval of time is called impulse. It is also equal to the change in momentum of an object for a very short time. It is represented with letter J. Its SI unit is Newton-seconds or N-s.

Impulse is a vector quantity i.e. impulse has both magnitude as well as direction. Its direction is as same as the direction of applied force. Mathematically, it can be written as :

$J=\int\limits{F} \, dt$

Hence, the correct option is (2) "impulse ".
