Question

which of the following is not a scalar?​

Answer 1

Answer!!!

Answer
Impulse (I)
Force∝
Time interval
1
​

Force=I
Time interval(t)
I
​

I=Force×Time interval
I−F.I
Since force is a vector quantity and impulse is the product of the sudden force applied and the time interval to bring equivalent the system. So Impulse also a vector quantity which have same direction to the force applied.

Answer 2

Mass, distance, time, and brightness are all scalar quantities. This is to say that none of these terms can be applied in a given direction. It would be illogical to have "three grams west" or "eighteen seconds to the left." Distance is the scalar equivalent of the displacement vector.
