Question

Which of the following is a vector?
a. pressure
b. surface tension
c. moment of inertia
d. none of these

Answer 1

Answer:

Surface tension is a scalar insofar as it is always oriented parallel to the surface.

In higher classes we say moment of inertia is a tensor quantity but in 11th class it is given that moment of inertia is a scalar quantity.

We can put the walls of our container anywhere inside the gas, and the force per unit area (the pressure) is the same. Therefore, pressure is a scalar quantity.

hence option D is correct.

Answer 2

Answer:

quantity has both magnitude and direction for example distance speed,time,temperature, work,energy,charge etc voltage are all scalar quantity displacement,force etc....

hope it helps you.. thank you

(d) none of them..
